Considerations for Underground Coal Mines That Operate Near

Mines in the late 1960' s were based on horizontal dril holes in the coal seam that were driled from a shaft sunk into a coal seam (Fields, H.H., et. aI, 1973). Several underground coal mines currently use horizontal in-seam techniques to extract CBM from locations inside the mine. A cross-panel horizontal hole system is shown in Figure 5.
