ERG Easy Slot Master Video 3
Longitudinal longhole retreat is a branch of the generic mining method known as sublevel stoping and often requires the development of a rise or slot prior to production blasting. Easy Slot eliminates thee need for raise bore or burn cut blast to create the rise or slot. Easy Slot is less expensive quicker to install and provides a bigger slot thus a better production blast.

World's Largest Zinc mines | How Zinc is mined | Where is Zinc mineral found?
Zinc is the fourth most mined metal in the world after iron, aluminum, and copper. It has strong anticorrosive properties and bonds well with other metals. Consequently, about one-half of the zinc that is produced is used in zinc galvanizing, which is the process of adding thin layers of zinc to iron or steel to prevent rusting. Large quantities of zinc are used to produce die-castings, which are important in the automobile, electrical and hardware industries. Antamina Zinc Mine, Peru: Antamina mine in the Andes Mountains of Peru is one of the largest copper/zinc mines in the world. It is operated by the consortium of leading mining companies, including BHP Billiton, Glencore and Teck, is the fifth biggest zinc producer. Antamina is one of the largest copper and zinc mine worldwide, and also a major producer of silver, lead and molybdenum. Rampura Agucha mine, India: Rampura Agucha Zinc-Lead-Silver Mine, located on a massive sulfide deposit in the Bhilwara district of Rajasthan, India. The mine has a combination of open pit mine and underground mine. The open pit operation includes drilling, blasting, loading, and hauling and Underground Mining is carried out using Long Hole Open Stoping with Paste Fill method with mined out stopes backfilled with cemented rock & with cemented tailing in paste form. Rampura Agucha mine is owned by Hindustan Zinc Limited (HZL), and has the world's largest deposits of zinc and lead. Cerro Lindo mine, Peru: Cerro Lindo Zinc Mine , Peru is the largest underground mine in Peru. Votorantim’s Cerro Lindo polymetallic mine is the sixth biggest producer of zinc and the largest underground mine in Peru McArthur River zinc mine: McArthur River open pit mine is one of the world's largest zinc, lead and silver mine in Australia. McArthur River mine will produce 383kt of zinc, 93kt of lead and 110t of silver in concentrate annually. This mine is operated by McArthur River Mining (MRM), a subsidiary of the Swiss mining company Xstrata. Red Dog Mine, Alaska, USA: Red Dog zinc mine, is the world's largest producer of zinc and has the world's largest zinc reserves. The mine site is accessible only by air or barge during the summer. Red Dog is an open-pit truck-and-loader operation, using conventional drill and blast mining methods. Red Dog is located on land owned by the NANA Regional Corporation and is operated by the commercial mining company Teck Resources in partnership with NANA Development Corporation. Mount Isa Mines: Mount Isa mine, Australia, is the largest source of zinc in concentrate of all Glencore's zinc mining businesses and third biggest mine worldwide. It is believed to have the largest resource base for zinc in the world. Both open-pit and underground mining methods are being utilized at Mount Isa.

Working Down the Mines
Pics I have scanned from my photos which have turned out quite well I thought. From when I worked underground 1968 - 1981. The first part is Windarra nickel mine, 212 miles north of Kalgoorlie Western Australia. This was a trackless decline with some pretty big gear, 35 ton Wigmore Caterpillar trucks which were a modified 631 scraper with a tipping body, and 3-boom Gardner Denver pneumatic jumbos. They had open stopes with longholes drilled with GD Airtracs and some bar-and-arm machines. From memory I think one of the big stope blasts was 100,000 tons. The mine closed in the early '80s and was gutted. There were a few deaths down there, all rockfalls, all on my shift, so R.I.P. to those guys. The second part is Lake View & Star gold mine, on Kalgoorlie-Boulder's Golden Mile. I worked there as a machine miner on airlegs doing shrink stoping and intermediate driving (drifting). We worked by ourselves with no partner which was the practise then. We used Holman's Silver 3s and Silver 900 airleg machines (jacklegs). Mucking out inter drives we used air or electric 2-drum scrapers into a raise. We used AN60 dynamite primers with ANFO and electric detonators or sometimes safety fuse. This was a "traditional" mine with rail drives leading to a vertical shaft about 3000' deep from memory. The mines on the Golden Mile no longer exist because they have been swallowed up by the Super Pit.

Bolting and Meshing an underground mine heading.
This is where the jumbo operator has finished scaling the heading to remove most of the loose rocks. He then manipulates sheets of mesh, 2.4m wide and up to 5m long, into position with the jumbo's boom(s). He then drills holes and 'bolts' (pins) the mesh onto the rock surface with a variety of 'rock bolts', measuring from 900mm long, to 3000mm long (generally about 47mm thick). My job is to train him how to do this, especially when using different and new bolts, that he might not be familiar with. This guy is an artist. No names, as we are not discussing which mine it is. I wrote him a nice report for his boss!

Juanita Mine Underground Exploration: Stoping, Inclined Shaft, and Bad Air
This is the first opportunity we've had for underground access. We were given permission to enter the mine by the landowner; he also said it was safe to enter. I'm inclined to agree, so long as one sticks to the main haulage level (documentation indicates that this is Level 4). The inclined shaft we found is clearly marked "bad air", which makes sense. It connects with workings accessed by the Traylor Shaft, which is an exhaust airway with beaucoup hydrogen sulfide coming out. Intake airflow is notable when entering or exiting Juanita; the portal is clearly an intake airway. The manway along the inclined shaft also didn't seen terribly stable. Given as we have no idea how deep the shaft went, and it appeared to have bad air, descent was quickly ruled out. We were a bit suspicious of the back the whole time through the main haulage tunnel. It was heavily-jointed, and small fragments seem to come off from time to time. Overall integrity seemed acceptable- I think that the arched design of the back binds this junk together and makes it stable. The complete lack of timbering outside of the stopes is notable. UPDATE: I've done some research, and the inclined shaft seems to be safe to enter during cooler months based on how natural-ventilation systems work. If proper ropes and anchors can be acquired, we'll be descending it this next spring.

Alimak raise climber
Raise Climber Mining Conditions This type of mining is best suited to tabular narrow vein ore bodies with enough dip for gravity ore flow. There is often considerably less waste development with raise mining than with regular open stoping. A narrow vein ore body has less ore to soak up waste development costs, making the raise mining method an obvious choice. It is better if the ore body is continuous over several hundred feet vertically. Experience has shown that raises from 75 to 150 metres length are the most economical. The method works best if the ore boundaries can be interpolated between adjacent raises. This allows the drill planning to be done before the production drill is set up in the raise. This is less important in sulphides, where the driller can tell if the bit is in ore by the colour of the cuttings. Raise Climber Mining Method Details The raise climber mining method will generally be comprised of the following steps: Development Bottom Sill: Access and haulage: These drifts are driven from the shaft or established mining areas to the new ore zone. The drifts are commonly sized to accommodate the large scooptrams used for production mucking and are often driven with jumbos. Drawpoints and Climber Nest: Drawpoints can be driven from either footwall or hangingwall, depending on how the ore zone is accessed. The climber nests are always in the hangingwall. The climbers require about 4.3 metres (14') width, 2.7 metres (9') of height and 12 metres (39') of length with extra added on for "Alicabs" and/or for low angle raises. The nest will be slashed out of the drawpoint backs if development is from the hangingwall side. Top Sill Access: These drifts are also driven from the shaft or existing development but, unless there is another lift, they often need only be large enough for the movement of supplies. Raises Raise Development: Raises must be driven big enough that a 2.4 metre (8') drill can be rotated within them, or about 2.7 x 2.7 metres (9' x 9') horizontally. Raise Rehabilitation: After the raise is driven it often must be rehabilitated, subject to ground conditions, for the safety of production crews. Hangingwall Support: Where required, the stope hangingwall can be supported with deformed strand resin-grouted cable bolts in a regular pattern along the raise. This is very cost effective as the raise is centred in the stope, which concentrates the support where it is needed most. Production Drilling: Drill holes extend to just less than half way to the next raise and are oriented slightly down from horizontal. The down dip helps the toes break to the stope wall. Hole diameters are often fairly small to avoid hangingwall / footwall damage in narrow veins. Loading & Blasting: The holes are most often mechanically loaded with either ANFO or an emulsion explosive. The blasts are timed to slash down, with the footwall holes often the last to fire. It is safest to take a few rings per blast, so that miss-holes or other blasting problems are accessible for correction. Mucking Swell: It is often best to leave ore in the stopes while blasting because of the support it gives. The broken ore often compacts slightly, resulting an effective swell of about one third its unbroken volume. Final Mucking: This step is done once the stope is completely blasted.

A Mine With Huge Stopes and Bottomless Pits - The Thompson Mine
Support us on Patreon: https://www.patreon.com/desert_dog_exploring I want to bring you quality footage and exposition of even more remote mines and mining camps. I hope I'm producing something here of sufficient quality to be worthwhile to you all. If not, your comments and suggestions for improvement are always welcome! -------------------------- Prologue - The Rant -------------------------- Do not do purposefully stupid things in mines. If you want to go up/down ladders with a rope, DO IT PROPERLY. In this video you'll see a really dumb, dangerous, and deadly way of securing a rope for an assisted descent. The physics were analyzed by our very own Engineer, and for the past 20 years, I've learned to trust him. In short, someone picked the WORST way to rig their mess. If you're going to use ropes for ascent/descent, PLEASE use proper ropes. In this video you'll see a cheap Home Depot/Lowes rope, with a dodgy knot These ropes are not rated for life safety use, they stretch a LOT, and the core is just crappy nylon. Honestly, you'd have been safer with genuine paracord for a line, and a proper rock bolt for an anchor. Not optimal, but better than the death trap someone left behind! End-O-Rant --------------------- As we wander through Nevada, Drunk Mike and I keep our eyes peeled. Despite comprehensive lists of abandoned mines, we sometimes miss things in our research. The headframe of the Thompson Mine looms in the distance, though it blends in well unless you're paying attention. We, along with The Engineer, stopped at the Thompson Mine for a look. I ended up with over an hour of footage, so this exploration is going to be split into at least 2 parts, possibly 3. This also marks the first use of the DJI Mavic Pro to capture surface footage of a mine, as well as use of the drone to do a "what's over the hill" recon. Overall, it's a very useful piece of equipment and will factor into our future explorations, as you'll soon see. In this segment we see some of the winzes, the main haulage shaft up to the headframe (more on that in part 2), and numerous drifts and crosscuts. The most impressive part of this mine was the enormous amount of cut-and-fill stoping. The use of raw logs for timbering of these stopes bears witness to the age of the mine - it began as a going concern in the 1880's, finally closing up in the 40's. Some work has been done between WWII and the modern day, but not enough to change the overall character of this place. Come along as we take a determined, but humorous, look at the Thompson Mine! As always, thank you for watching. Also, as this channel grows towards 1000 subscribers, stay alert for the 1000th subscriber giveaway!

www.imaker.ca AMERICAN PARAMOUNT GOLD - MINING IN THE US SCRIPT: Stunning desert vistas shine bright as American Paramount Gold prepares to develop its Cap Gold project. Located northwest of Las Vegas, between Tonopah and Rachel, Cap Gold borders the Nellis Air Force Base. Covering six square miles, this high-potential, under-explored property sits in a 10-mile wide by 50-mile long stretch of the celebrated Walker Lane Trend. Since 1859, more than 40 million ounces of gold and 540 million ounces of silver have been mined in Nevada– with more to come! Historic drilling at Cap Gold points to solid potential for both underground and open pit gold and silver deposits. A recent geophysical survey confirms that previous drilling represents only a very small portion of Cap Gold’s potential. Core results validate the strength of high-grade gold and silver first intersected by RC drill holes. Open pit grade intersections include 35 feet of 1.06 grams gold and 14.7 grams silver per tonne. Similar properties in Nevada and other areas of the world have produced an excess of 2 million ounces of gold. Cap Gold holds both high-grade underground, and large low-grade open pit gold and silver mine potential. American Paramount is moving forward with development, focusing on creating the greatest possible gain for shareholders in the shortest possible time. A drilling-heavy exploration and development program, budgeted at $2.5 million, is scheduled to begin in mid 2010. Join American Paramount as it captures the bounty at Cap Gold! About ImageMaker Inc.

4850 Level Dedication - June 22, 2009
On Monday, June 22, 2009, Gov. Mike Rounds and Mr. T. Denny Sanford dedicated the Sanford Underground Science and Engineering Laboratory at Homestake during an unusual ceremony 4,850 feet underground in a former gold mine. The ceremony was in a large tunnel -- 14 feet wide by 14 feet tall -- that connects the Ross and Yates shafts on the 4,850-foot level of Homestake. The guests wore hardhats and mine lamps, but the tunnel (a "drift" in mine parlance) was lit, the temperature was 70 degrees and there was a steady breeze thanks to a large exhaust fan on the surface. The "ribbon cutting" was done in the style of hard-rock mining. Former Homestake gold miners Bill Heisinger and Alvin Burns used a traditional "jackleg" drill to punch holes into the wall of a tunnel. Then Gov. Rounds and Mr. Sanford lifted into place a plaque dedicating the Sanford Underground Laboratory at Homestake.
