Jul 03, 2015 7.3.4 Highwall Mining. Highwall mining is very similar to auger mining in its concept, where the entry into the coal seam in made at the highwall of the ultimate pit limit. The difference lies in the use of a more sophisticated machine, known as a highwall miner. The highwall miner shares some common elements with a continuous mining machine. One presentation featured Pieter-Jan Kleiterp, an application specialist for Caterpillars Highwall Miner product line who presented a site evaluation tool that helps sites determine if highwall mining is technically feasible for the location. The online tool requires requires 12 different parameters to be entered Strength of immediate ... Sep 01, 2019 Highwall mining is a technique for attaining additional coal recovery after the economic strip limit is reached in surface mining. It involves remote deployment of a continuous miner in openings beneath the final highwall, with no personnel entry. Many candidate areas for highwall mining have thick and steeply dipping seams.

Jan 05, 2015 IS HIGHWALL MINING THE RIGHT CHOICE? Another common question by prospective highwall miners, according to Fairchild, is how a company knows when the highwall option is a feasible one. The response is something into which Cat has put much thought. As a result, the OEM has developed a Web-based site evaluation tool to help mining companies ... These highwalls were generated as part of normal strip mining operations and as a result were not specifically designed or engineered with highwall mining in mind. The German Creek Highwall Mining Project was carried out by CAPCOAL and commenced in 1993 to examine the geological and geotechnical feasibility of highwall mining to extract coal ... Dec 01, 2013 Highwall Mining is an important surface coal mining method in many countries such as the US, Australia and New Zealand. In the US it may account for approximately 4% of total U.S. coal production . Highwall Mining technologies originated in the USA in the mid 1970s and have seen widespread use since the early 1980s.

PreFeasibility Study for Highwall Mining at Curragh North

The primary focus for this thesis is to investigate the feasibility of highwall mining operations at the Curragh North mine. Highwall mining is best defined as the method whereby underground coal is directly extracted from the coal seam of an open cut highwall in a surface controlled operation by making repeated entries or drives into the seam. Highwall mining is a hybrid of surface mining and underground mining methods, and is often the only feasible method to recover the coal reserves in the central Appalachian coalfields due to the steep terrain and the closely spaced multiple thin coal seams. Highwall mining is an important surface coal mining method, and it may account for approximately 4% of total U.S. coal production. Highwall stability is the major ground control related safety concern. Ground control plans for highwall mining should specify hole width, web pillar width, barrier pillar width and number of holes between barriers.
