摘要
巨野煤田彭庄煤矿首采工作面回采巷道胶结性极差、易离层,岩性不稳定,根据围岩岩性和矿压观测结果,计算出了合理的支护参数,验证了支护方式的有效性,为巨野煤田同类井田的地质条件的巷道支护提供依据。
the gleyness of mining gateway in the first coalface in Pengzhuang Coal Mine,Juye coalfidd is worst, and it is easy to form abscission layer.The lithology is unstable. According to the results of surrounding rock' s lithology and the observation of mine pressure, the reasonable support parameter is calculated and the effectiveness of support pattern is verified,which provides the basis for roadway support on the geological conditions of the similar well fields in Juye coalfield.
