摘要
对矿井基本信息和地质条件的表现特征进行分析,并且针对巷道断面的应力情况和位移情况进行模拟试验,讨论不同断面形状的优缺点,结合断面形状提出提高采掘效率的方案,以期望可以通过合理、安全的采掘方案,满足煤矿企业的采掘需求。
This paper analyzes the basic information of the mine and the characteristics of the geological conditions,and carries out simulation tests for the stress and displacement of the roadway section,discusses the advantages and disadvantages of different section shapes,and then proposes a plan to improve the mining efficiency in combination with the section shape,in order to meet the mining needs of coal enterprises through a reasonable and safe mining plan.
