| 摘 要： | 蔡园煤矿中部发育一条走向近NW向的正断层,对开采12煤层有影响,在分析断层特征及水文地质条件基础上,采用超前帷幕注浆技术对断层破碎带进行了加固,并对影响断层富水性的灰岩含水层进行了预注浆封堵,实现了对断层破碎带加固、堵水的双重效果,达到了巷道围岩加固及含水层改造的双重目的,保证了巷道的安全通过。

| Abstract: | A normal fault with the trend of approximate NW developed in the center of Caiyuan Coal Mine, which has influenced the mining of No. 12 coal layer. Based on analysis on characteristics and hydrological conditions of the faults, by using the advanced curtain grouting technique, fracture zones have been reinforced, and sealing grouting has been carried out in waterbearing limestones which will influence water abundance. Thus double goals have been realized, one is the reinforcement of fractural zoned, the other is the water shutoff. Double goals have been gained, that is oadways and aquifer transformation. Consequently, the safety of passing through the roadway can be ensured. |
