摘要
本文以安居煤矿2308工作面运输巷为研究对象,通过数值模拟的方式,对比分析不同锚杆长度及间距等因素影响下的支护情况,对其进行了支护优化设计。结果表明:所设计的巷道掘进支护在保证可靠性和安全性的同时,不仅能够降低支护成本,还能加快掘进速度,实现高产高效。
This paper takes the transportation roadway of the 2308 working face in Anju Coal Mine as the research object,compares and analyzes the support situation under the influence of different bolt length and spacing and other factors by the way of numerical simulation,and carries out the support optimization design.The results show that the designed roadway driving support can not only reduce the support cost,but also accelerate the driving speed and achieve high yield and high efficiency while ensuring the reliability and safety.
