Abstract:

Abstract: Based on the engineering geological exploration, using the exploration results and experimental data, the article analyzed the  stability coefficient of residual coal slope and obtained that the residual coal had great effect on slope stability. From the feasibility of the program, long-term benefits, economic benefits and other aspects, the author comprehensively analyzed the residual coal reserves, all clean, part of the clean-up and other programs. Through the analysis and comparison of different schemes, the author suggested adopting full clean-up program.
