Mine Plan - an overview | ScienceDirect Topics

The goal of coal pit recovery is to obtain as close to as possible. One method to maximize pit recovery is to minimize drill and blast damage to the top of the coal. Drill and blast damage is reduced by stopping the drill holes from touching the coal seam or by placing nonexplosive material in each drill hole, called stemming.

Public Notice

The recovery of coal would require excavation of the overlying soil and rock materials, and mining through wetlands and streams as the operation advances across the 3084.6-acre site. Sediment basins would be developed as close to the mining area as possible to effectively induce sedimentation from surface runoff of the disturbed areas.
