Abstract:

Basing on the analysis of the rock burst occurred characteristics from Qianqiu Coal Mine, we research the influence of the rock burst formation on coal mine geological factors and mining technology factors. It is the rock burst forming geological factors and internal factor，that the coal seam has the bump proneness and the mining depth arrival the critical depth of rock burst frequency, increase rock burst hazard of horizontal tectonic stress , and there are thick hard rock exist in overlying strata. It is the mining technology factors and inducing factors of incident rock burst in the lower roadway, the lower roadway is located in the middle position of high stress island area formed by coal face skip-mining and the working face supporting strength than roadway.

Key words: rock burst, coal mine geological factors, mining technology factors, island working face
