针对古书院矿西二盘区变电所巷道围岩受采动影响存在底鼓变形的问题，对巷道底板及侧帮围岩状况进行了分析，窥视结果显示巷道围岩裂隙较多，原有的锚杆、锚索支护难以达到预期的支护效果。提出了高压注浆配合高强锚索支护的加固方案，并进行了实际工程实践，经巷道围岩表面位移监测检验，表明高预应力锚索、注浆联合支护是动压底鼓巷道安全、有效、经济的支护方式。

In order to solve the floor heave deformation by the surrounding rock of roadway mining influence in the west two panel substation of GushuyuanMine ,with the surrounding rocks analysis of the roadway floor and side, the peeped result showed that surrounding rocks had lots of fractures , original anchored cable and rod supporting system had performed worse on the support effects.The treatment scheme was permanent support with high pressure grouting and high strength anchor cable ,through monitoring the displacement of surrounding rocks by the engineering practice , it was the final conclusion that the high pre -stressed anchor cable and grouting support is safe ,effective and economic way of supporting of kinetic pressure floor heave roadway.
