高应力破碎巷道支护技术研究

Study on high stress crushing roadway support technology

针对曲江煤矿40106工作面高应力破碎巷道围岩变形严重、支护困难的问题,通过现场调研,找到影响巷道围岩稳定性的主要因素有地应力、围岩强度、围岩的化学组成,提出采用"锚杆、金属网、U型钢拱支架、喷浆、注浆和锚索"的联合支护技术,并在轨道巷进行试验。实践表明,该方案支护效果达到了预期的支护要求,保障了生产工作的顺利进行。

In response to the problem of severe deformation of the surrounding rocks and the difficulty of support,the main factors affecting the stability of the surrounding rocks were ground stress,the strength of the surrounding rocks and the chemical composition of the surrounding rocks,which were identified through field investigation.Practice showed that the program support effect achieved the expected support requirements,ensuring the smooth progress of mining.
