Geological Survey and Comprehensive Analysis of a Dangerous Slope in the Weibei Limestone Mine

Abstract There are abundant limestone resources in Weibei area. However, under the influence of a complex geological environment and harsh external environment, they often suffer from various types serious disasters, which seriously threaten safety people mining area development resources. Therefore, it is urgent to carry out relevant governance. Firstly, combined with field engineering data typical quarry slope Weibei, this paper makes detailed survey study Then, geometric model mine established analyze stress relationship between each block its failure mode. Finally, deep Newtonian force monitoring early-warning system set up dangerous large deformation early warning treatment reinforcement. The results show that (1) main component mine, followed by mudstone, developed joints fissures, broken rock mass, high hidden danger disasters; (2) addition bending toppling on surface slope, there three modes: along joint surface, plane, outward structural plane; (3) NPR anchor cable used strengthen real-time changes realized, has particular reference significance for similar significant mechanisms imminent slide warning.
