摘要
为进一步提升煤矿生产效率和安全性,要求岩巷掘进效率与煤巷的开采效率相匹配。以324岩巷为例,在研究其岩层特性及断面基本结构的基础上,对当前325岩巷所采用的掘进工艺下的掘进问题进行总结分析,并结合理论计算初步确定两种优化掘进方案,结合数值模拟最终确定掘进工艺中对应爆破方案的掏槽眼的具体参数。
In order to further improve the production efficiency and safety of coal mine,it is necessary to match the driving efficiency of rock roadway with the mining efficiency of coal roadway.Taking 324 rock roadway as an example,on the basis of studying its rock stratum characteristics and the basic structure of section,this paper summarizes and analyzes the tunneling problems with the current 325 rock roadway driving technology.Combined with theoretical calculation,two optimized tunneling schemes are preliminarily determined.
