Discussion of Sandstone Outburst Mechanism by Rock Drivage in Deep Mine Coal-Bearing Strata

Abstract:

When tunneling deep sandstone roadway of-350m level in Yongrong mining area, it appears frequent occurrence of rock burst and gas dynamic phenomenon. Through discussing tectonic stress field, tunneling stress field, self-weight stress field and physico-mechanical properties of middle-fine sandstone, this paper draws sandstone outburst mechanism with rock drivage in mine coal-bearing.
