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.

How Raise Drill Works
 
06:37
Raise drilling is used to create large drill holes -- up to 7.6 meters in diameter. The holes, or tunnels, are used to connect mine shafts, power plant tunnels or channels for rainwater and surplus water, as well as for ventilation between different levels in a mine. This type of drilling is performed in two stages. First you drill a smaller pilot hole and then you swap the smaller drill bit with a reamer. The reamer is equipped with reels made of hardened metal which have the same diameter as the final hole. The hole is expanded as the reamer crushes the rock using both pressure and rotation. Raise drilling can be used for holes and tunnels of up to 1100 meters in length, which makes this method very practical for many applications. https://engineers-channel.blogspot.com/p/raise-drill.html

Raising the bar
 
01:31
Raise boring was developed to meet underground mining demands, but new applications continue to arise due to its inherent safety benefits and other advantages over conventional drilling and blasting. Raise boring can be used for a variety of mining applications, from ore shafts to shafts for ventilation, water or cable installations. The raise boring method enables construction of circular mechanized shafts between two mine levels without the use of explosives. A borer is set up on the upper level and drills a narrow pilot hole, typically between 23 and 35 centimeters, to accommodate a drill string. A reamer head is then attached to the drill from the lower level and raised back towards the machine. Sandvik raise boring heads optimize the performance of the boring machine through high penetration rates, great stability, low vibration and low torque demands. Together with the company's high-performance pilot bits, they enable shafts and holes from 0.66 to 6.0 meters in diameter to be bored to depths of up to 1,000 meters — quickly, economically and safely.

Working Down the Mines
 
02:32
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.

Fragmentation Analysis for Underground Drawpoints and Muckpiles for Mining
 
09:33
Listen to Principal Scientist Matthew Thurley present examples of fragmentation analysis for both underground and open-pit mining. Fragmentation sizing based on automated analysis of 3D laser scanner data. Our advanced algorithms provide a stable and reliable result because they overcome limitations of existing systems, including being fully automated, detect areas-of-fines and overlapped/non-overlapped rocks. Size results represent the reality of the visible rocks at the time of measurment

Autonomous drone flight into a mine stope
 
05:51
Autonomous flight into an underground mine stope to explore and map it in 3D. The Hovermap payload enables this by providing GPS-denied flight and collision avoidance. In this trial the drone was tasked to fly to a set of pre-defined waypoints. It descended only 5m into the stope but still obtained a dense and relatively complete map. In future the drone will autonomously explore the stope to ensure full coverage without the need for pre-defined waypoints.
