当前,在煤矿企业的巷道掘进工序中,煤巷锚杆支护是采准巷道支护有效的一种方式,得到广泛了应用。其技术相对先进、不但能够强化巷道围岩强度,支护成本经济合理,而且能大大减少工人的劳动强度、安全稳定。本文从实际出发,首先阐述了推广煤巷锚杆支护快速掘进技术的重要性,然后分析了制约锚杆支护技术因素,最后提出提高锚杆支护安全可靠性的相关措施。
At present, in the tunneling process of coal mining enterprises, coal roadway bolting support is an effective way to adopt quasi laneways and is widely used. Its technology is relatively advanced, not only to strengthen the surrounding rock strength, supporting the cost of economic and reasonable, but also greatly reduce the labor intensity of workers, security and stability. Based on the actual situation, this paper firstly expounds the importance of popularizing bolting technology in coal roadway, and then analyzes the factors that restrict the bolting technology. Finally, it puts forward some measures to improve the safety and reliability of bolting.
