Abstract
Nalinhe mining area is a deep area developed by Dongsheng Coalfield in recent years,and there are widespread natural disasters of rock burst existing.Taking Yingpanhao Coal Mine as an example,this paper analyzes the rock strata,coal seam impact tendency,and geostress in the upper part of the mine.The stress changes,pressure step distance,and high-energy events in the mining and excavation working face are analyzed.The occurrence mechanism of rock burst under the combined conditions of large burial depth,thick coal seams,and upper extremely thick rock strata in the mining area is summarized.The main disaster causing factors are high stress in the original rock,failure and instability of the coal body along goaf,combined with the superimposed influence of cross points of connecting roadways,anticline structures and so on.The characteristics of rock burst in Nalinhe mining area are summarized,providing reference for the prevention and control of rock burst in this mining area.关键词
