摘要： 针对寺河煤矿岩巷受薄煤层瓦斯影响的问题，为提高突出矿井岩巷的掘进速度，依靠“地质先行”的理念，
以寺河煤矿回风大巷和辅运大巷岩巷为研究对象，基于煤岩层对比情况，结合支护、防突、瓦斯治理以及防治水方面的
内容进行对比分析。根据同一支队伍在不同层位掘进的实际情况，对比分析掘进效率，提出了沁水地区以寺河矿为背景
的高突矿井岩巷层位选择的最优方案，即沿K5 灰岩掘进（顶板距离突出煤层大于10 m，顶板坚硬，不易冒顶；巷道断
面为泥岩，易截割；底板为灰岩，不易窝机等），另外提出了掘进过程中层位控制方法。

Abstract: Aiming at the problem that the rock roadway in Sihe Coal Mine is affected by thin coal seam gas, in order to improve
the excavation speed of the rock roadway in outburst mines, relying on the concept of "geology first", taking the air return roadway
and auxiliary transportation roadway in Sihe Coal Mine as the research object, based on the comparison of coal and rock strata,
combined with support, outburst prevention, gas control, and water prevention, a comparative analysis was conducted. Using the
actual situation of the same team tunneling at different layers, and comparing and analyzing the tunneling efficiency, it was
proposed that the optimal scheme for selecting the rock roadway level in high outburst mines in Qinshui area, with Sihe Coal Mine
as the background, was to tunnel along K5 limestone (the distance from the roof to the outburst coal seam is greater than 10 m,
the roof is hard, and it is not easy to fall off; the roadway section is mudstone, which is easy to cut; the floor is limestone, which is
not easy to nest the machine, etc.), and a layer control method during the tunneling process was also proposed. Key words: outburst mine; rock roadway; layer control
