摘要
为进一步提升煤矿工作面的开采率和安全性,以某煤矿3号煤层工作面为例在分析其地质、水文以及煤层等条件的基础上,对切顶卸压自成巷开采技术的适用性进行研究,并对采煤高度、切顶高度、切顶角度等开采参数进行最优化求解。
In order to further improve the mining rate and safety of coal mining face,taking coal seam No.3 as an example,on the basis of analyzing its geological,hydrological and coal seam conditions,the applicability of mining technology of cutting roof pressure relief roadway is studied,and the mining parameters such as coal mining height,cutting top height and cutting top angle are optimized and solved.
