摘要
庞庞塔煤矿5-105工作面正巷在开掘过程中,依据巷道断面大、煤层倾角大、局部顶板破碎及围岩松软的实际情况,优化支护设计,改进施工工艺,采用锚网梁+锚索联合支护,确保了围岩体的稳定可靠和工程的经济合理性。
In digging of 5-105 working face of Pangpangta Mine,the laneway section and coal seam obliquity is bigger,local top is cracked,and surrounding rock is floppier.To insure stabilization of surrounding rock and economics of engineering,bolt supporting design must be optimized and improve construction technology by applying anchor and cable combined-support.
