Aiming at the abnormal strata behavior in the advance entry of 1303 fully-mechanized working face in Xinglongzhuang coal mine,the movement rule,characteristic,step distance of fracturing,position and mode of fracturing of the overlying strata in mining process is analyzed by using the key strata theory.
針對興隆莊煤礦一采區1303綜放工作面超前平巷發生奇異壓力的現象,采用關鍵層理論對在采動過程中的上覆巖層運動規律進行了詳細的力學分析,研究了它們的運動特征、破斷步距、斷裂位置、斷裂方式以及對工作面及其超前平巷的來壓規律,對比分析了該工作面礦壓實測數據與理論研究成果。
