摘要
软岩具有前期阶段来压快、时间短、变形大、自稳能力差等特点,软岩巷道支护也成为一个不易攻克的难题。根据刘桥一矿二水平六采区-380m运输石门外段巷道的工程性质,设计三种支护方案,采用数值模拟方法,对不同支护形式进行比较分析,优化选择最佳的支护方案,以确保巷道能够安全可靠、经济合理地进行开挖。
Soft rock in early stage has the characteristics of rapid pressure, short time, large deformation and poor stability etc, thus the soft rock roadway support has become a difficult challenge. According to the engineering properties of roadway in Liuqiao Mine, three kinds of supporting schemes are presented. By using numerical simulation method, different support forms are analyzed and the optimum supporting scheme is selected, which ensure that the roadway excavation is safe, reliable, economic and reasonable.
