Application Analysis of High Dip Angle Comprehensive Mining Face Passing Fault Comprehensive Mining Technology
In order to improve the safety of Huasheng Energy Group's 6134 high angle working face passing through faults,it has been decided to adopt a combined comprehensive mining operation technology of geophysical exploration,grouting reinforcement,and leaving a roof at the bottom to pass through faults underground.For the first time underground,Malisan was used as grouting material to improve the strength of fractured surrounding rock,and for the first time,the underground top crossing fault method was used to improve the stability of crossing faults.Through the analysis of practical application effects,the new comprehensive mining technology scheme can effectively ensure the safety of mining through faults,providing a certain reference for mining through faults in other mines.
