Operational performance data, from the BryDet 2348-72, was analysed to quantify the influence of cutter head diameter, coal type and penetration depth upon mining rates. Figure 3 shows a summary of the US Patent for Auger mining system Patent (Patent,A mining apparatus 10 to mine coal from a seam 11. The apparatus 10 includes a continuous miner 12 to form a mine road 13. Extending along the road 13 is a conveyor 15 having a forward end 20 to which the mined material from the continuous miner 12 is delivered. The apparatus 10 further includes an auger mining machine that advances an auger drill string 28 into the coal seam 11 in a direction Design of Auger highwall mining SlideShare,Auger mining consists of cutting head, auger flight, and latching mechanism. The working process of auger miner is very common. Firstly, the auger cutting head drives directly from the auger 2. machine into the coal seam and additional flights are added as the hole deepens. Once each flight is in place, a tractive effort is provided by hydraulic rams. Each auger flight is connected via a latch coal mining auger equipment sale bockelmann-coaching.de,coal mining auger equipment sale.
