复杂条件下巷道围岩加固技术研究

Study on the technology of reinforcing roadways under complex conditions

针对牛儿庄矿高应力环境下松散破碎围岩巷道存在的支护问题,采用壁后充填和锚杆锚固与注浆联合支护技术加固巷道围岩,较好地解决了巷道支护问题,取得了较好的技术经济效果。

To solve the problems in supporting roadways with bulky and broken surrounding rocks under high ground pressure in Niuerzhuang Coal Mine, the combined supporting method with backfilling, bolting and grouting is adopted to reinforce the roadways, and the satisfactory technical economic effect is gained.
