本文从自然因素和开采因素方面,对石洞沟煤矿急斜临界角近距离薄及中厚煤层群分组联合开采巷道矿压显现进行了研究。通过现场数据的搜集、整理与分析,得出了上下煤组、上下区段及同组煤内上下煤层间同时开采的合理错距和相互影响范围,为矿井生产提供了可靠的科学依据。
In this paper, from the aspects of natural factors and mining factors, the strata pressure of coal mine in Shidonggou coal mine is studied. Through the collection, sorting and analysis of the field data, the reasonable error distance and mutual influence range of simultaneous mining between the upper and lower coal seam in the upper and lower coal group, upper and lower sections and the same group of coal are obtained, which provides a reliable scientific basis for mine production.
