箭竹坪矿区主采煤层顶底板稳定性分析

The Mine Roof and Floor Stability Analysis of Main Coal in Jianzhuping Mining Area

本文通过收集和整理箭竹坪矿区资料的基础上,对矿区的地层、构造、顶底板岩性组合等方面进行了研究,并对整个矿区主采煤层顶底板的地质条件做简要分析。分析结果表明箭竹坪矿区主采煤层顶底板的稳定性差异比较大,其中煤层中的后期小构造和顶底板岩性被视为顶底板稳定性的主要控制因素。

By collecting and collating Jianzhupings mining area in the previous census detailed investigation and survey information meeting on the basis of the mining area of stratum, structure, roof and floor lithology portfolio, and other aspects of the study, the main coal mining area and the entire roof and floor of the A brief analysis of geological conditions. The results showed that the lower bound of the main coal mine roof and floor of the stability of relatively large differences. One small seam in the late tectonic and roof and floor roof and floor lithology be regarded as the stability of the main factors control.
