摘要
针对坪上煤业23011巷构造应力场复杂、开采扰动影响强烈等情况,对巷道的初始设计进行分析改进,提出一次使用顺槽巷道锚杆支护的初始设计方案。通过现场监测数据表明,改进后的设计支护效果良好,且成本低、维护量小,有效提高了掘进效率。
In view of the complex structural stress field and the s trong influence of mining disturbance in 23011 roadway of Pingshang coal industry,the initial design of roadway is analyzed and improved,and the initial design of bolting support is put forward once.The actual monitoring data show that the improved design support effect is good,and the cost is low and the maintenance quantity is small,which effectively improves the tunneling efficiency.
