摘要(Abstract)：

山西太原古交矿区马兰煤矿主斜井底水仓布置在奥陶系顶部隔水关键层内,其底板为奥陶系峰峰组灰岩,隔水层厚度4.17 m,受到底板奥灰承压含水层的严重威胁。为了消除突水隐患,在水仓底板岩石变形破坏机理模拟研究的基础上,同时考虑到研究区奥灰含水层距离近、水量大的特殊情况,探索出一种新型注浆加固方法对水仓底板进行注浆加固,并取得了良好效果。设计为一钢筋混凝土盖先覆于水仓底板上,同时用加强筋与围岩连接,之后再采用浅孔低压与深孔高压交替注浆充填的方法进行加固。此方法使水仓底板与围岩成为一个整体,对浆液起到封闭作用,使底板更加稳固。
Xishan coal electricity group Malan coal mine who′s main slope bottom water warehouse layout within the Ordovician top water-resisting layer. Water warehouse floor is the Ordovician limestone Fengfeng Group and by serious threat of the Ordovician limestone aquifer. In order to eliminate the water inrush hazard, in view of water warehouse floor rock deformation characteristics and closer, high water pressure of aquifer, with large amount of water, adopt new design materials for the water warehouse floor of grouting reinforcement, which achieved good results. New design materials is a new design of reinforced concrete cover who′s covered in water warehouse floor. Using the shallow hole grouting low-voltage alternating with deep hole high pressure grouting filling way. The new method increased with the integrity of the surrounding rock and closed grout, making the floor more stable.
