Surface Mining Methods and Equipment - EOLSS

Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden. A continuous miner with single or multiple augers/cutting heads is operated underground and controlled remotely by crew located outside. Augering can be regarded as a supplementary method for open cast mining in cases when coalCHAPTER 11 Mining Technology - Princeton University,derground coal mining technologies in the West, including:1) capital require- ments, 2) resource recovery, 3) labor, 4) production and productivity, 5) envi-ronmental impacts, and 6) health and safety.

Introduction to Longwall Mining and Subsidence ver2

In longwall mining, a panel of coal, typically around 150 to 300 metres wide, 1000 to 3500 metres long and 2 to 5 metres thick, is totally removed by longwall shearing machinery, which travels back and forth across the coalface. A typical section through a coal face is shown in Fig. 1.2 and a photograph of typical longwall face equipment is shown in Fig. 1.3. The shearer cuts a slice of coal,CHAPTER 11 Mining Technology - Princeton University,derground coal mining technologies in the West, including:1) capital require- ments, 2) resource recovery, 3) labor, 4) production and productivity, 5) envi-ronmental impacts, and 6) health and safety.
