Risk Assessment of Rockburst with a LS-FAHP-CRITIC Method: A Case in Gaojiapu Coal Mine, North of China

Rockburst is one of the main dynamic disasters in coal mines; it great significance to accurately evaluate risk zoning rockburst for mine safety construction and pressure relief design. Taking Gaojiapu Bingchang mining area Shaanxi Province as study area, this paper quantifies complex geological structure based on fractal theory establishes evaluation model index by LS-FAHP-CRITIC method combination with distribution characteristics field stress field, structure, sedimentary environment seam overburden. A new proposed, was evaluated. The results show that dangerous areas are widely distributed, mainly near high maximum horizontal principal stress. On basis actual mine, where occurs all located which verifies accuracy rationality method. This can be used guide production similar mines or adjacent coalfaces.
