深井矿压强烈,沿空巷道围岩控制相当困难,在综放工作面掘进过程中常留一定数量的窄煤柱。通过了解沿空窄煤柱巷道围岩的破坏变形特征和锚杆与围岩相互作用机理,选择合适的锚杆支护理论和技术,可大大提高围岩稳定性。
深井礦壓彊烈,沿空巷道圍巖控製相噹睏難,在綜放工作麵掘進過程中常留一定數量的窄煤柱。通過瞭解沿空窄煤柱巷道圍巖的破壞變形特徵和錨桿與圍巖相互作用機理,選擇閤適的錨桿支護理論和技術,可大大提高圍巖穩定性。

The mine pressure of deep shaft is intense, so the surrounding rock of gob side roadway is very difficult to control and some narrow coal pillars are often leaved in tunneling process of fully mechanized caving face. By understanding the characteristics of deformation and destruction of surrounding rock of gob side roadways and the interaction mechanism between bolt and surrounding rock, the appropriate bolting theory and technology is selected, which can improve the stability of surrounding rock greatly.
