highwall mining cost

Highwall mining is an efficient, proven and durable method for mining coal from exposed horizontal seams producing an average of 110 000 tonnes 120,000 tons of coal per month in coal seams up to 300 m 1,000 ft in seams dipping up to 8 degrees recovering up to 70 percent of in place coal. Cost effective extraction: The HW300 is a

Highwall mining. High wall mining is another form of surface mining that evolved from auger mining. In high wall mining, the coal seam is penetrated by a continuous miner propelled by a hydraulic Push beam Transfer Mechanism PTM Attachments 1. Highwall Mining . Related Courses. Exam System Safety

Highwall mining is a hybrid form of mining that accesses coal reserves from the base of an exposed highwall. It is typically used when the surface mining operation reaches the economic limitation imposed by the stripping ratio. Highwall mining can extract the remaining ore at low capital cost than underground mining and uses different equipment

The HW300 produces high volumes of coal at very low costs. More importantly, it is safer than traditional underground mining, as it sends no one underground, and it works economically

2015 7 3   The highwall miner can advance 1200' under the highwall compared to a typical 300' for an auger. Recovery rates improve from roughly 30% for an auger to near 50% for a highwall miner. The highwall miner can adapt more
