摘要
以无煤柱作业面沿空巷道支护优化为对象开展探究。结合具体工程实际,在分析巷道原支护方案不足的基础上,对支护开展全方位优化设计。结果表明,优化后的支护实现了对巷道围岩的有效控制,提升了作业的安全性和有效性。
This paper studied the support optimization of gob-side entry in no-pillar working face.Combined with the actual engineering,on the basis of analyzing the deficiency of the original support scheme,it carried out all-round optimization design for the support.The results show that the optimized support can effectively control the surrounding rock of roadway and improve the safety and effectiveness of operation.
