Abstract
In Chap. 6, the design method for directional cutting parameters and anchoring support parameters of AFR mining method was established. The successful application of AFR mining method in different buried depths, and roof types in mines was carried out. At present, it has been successfully applied in over 100 mines. This chapter focuses on different types of mine working faces including shallow buried depth, deep buried depth, weathered roof strata, broken roof strata, near the overlying mined coal seam and other typical examples. It effectively ensures the coal mining safety, eliminates mine pillars, and reduces roadway excavation, which has certain safety and economic advantages.
