Abstract: Abstract: For effective prevention and control of mine bumps accident which happened in 73 on 29 island coal face, respectively, using the comprehensive index method and probability index method to evaluate macroscopic face impact ground pressure hazard, integrated strata movement factors and factors divided by the coal mining face impact ground pressure hazard area, finally to put forward the prevention and control of different solution, for the similar geological conditions provide certain reference prevention and control of the island coal face of impact ground pressure.
