摘要
结合新安煤矿的生产实际,分析了回采工作面和采区巷道顶板动压力的现象,并阐述其拄制方法。控制回采工作面和采区巷道顶板动压力显现的破坏,要做好矿压观测工作、顶板舜压的预报工作和瓦斯抽放工作。
In combination with the actual production of Xin＇an Coal Mine,the phenomenon of dynamic pressure at the coal face and the mining area roadways was analyzed.The control methods were expounded.In order to control the damage of dynamic pressure appear at the coal face and the mining area roadways,some work should be done,such as the observation work of rock pressure,the prediction work of roof instantaneous pressure,and the work of gas drainage.
