Ground pressure behavior law at fully-mechanized face in Fenxi-ShuGuang coal mine

Procedia Earth and Planetary Science, 2009
AbstractIn this paper, based on field observations and theoretical analysis, we discussed the ground pressure behavior law and its characteristic at fully-mechanized face and the material roadway of 10# seam in Fenxi-Shuguang coal mine. The analysis results indicates that ground pressure at material roadway increased sharply when the working face ...
