Proposal of a methodology for identifying the optimal coal seam inclination range suitable for the operation capabilities of mechanized complexes for mining gently inclined to medium inclined coal seems

Abstract

The inclination of the seam and its variations are significant adverse factors that cause instability and difficulty in controlling the slide of mining mechanized complexes in the seam dip direction (working face). The cost of time and manpower to handle sliding incidents is relatively large, even causing collapse of working faces if working stability in the seam diping direction cannot be controled. Therefore, the article introduces the method of determining the optimal coal seam inclination angle range suitable for operation abilities of mechanized complexes for mining gently inclined to medium inclined coal seam.
