| Abstract: | Based on the in-situ measurements of ground pressure and physical and mechanical properties of rocks in Guhanshan coal mine,and analysis of minerals composition and fissures in rock,the type of soft rock was determined to investigate the deformation and failure of surrounding rocks and floor heave happened in extremely soft rock roadway in Guhanshan coal mine, which provides the basic news for support of rock soft. |

| Keywords: | soft rock floor heave ground pressure joint |
