A numerical simulation on mining pressure law of mechanized mining face in Chang Gou yu Mine

The article took Chang Gou yu coal mine for example. Based on the scene investigation and the ore presses monitor, According to the geological conditions of Chang Gou yu coal mine,we made the numerical simulation of mining face. After analyzed the abutment pressure and it's coverage of the first caving, the old roof first weighting and the old roof periodic weighting, Combined with the mine pressure monitoring data and the mine pressure appear law of the mining face, the article can take some reference for safety, high production, and efficiency exploitation.
