箭竹坪矿区构造特征及其对煤炭开采技术的影响

本文在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了简要分析。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,煤层中的后期小构造被视为影响煤炭开采的主要控制因素。

Structural Features of Jianzhuping Mining Area and Influence on Coal Mining Technology

On basis of collecting and collating Jianzhupings mining area materials makes a study of stratum,structure,roof and floor lithology combination est.aspects of mining area,a brief analysis of the main coal mining area roof and floor geological conditions is made.The results show that the stability of the main coal mine roof and floor have relatively large differences.The late small tectonine are regarded as the main factors of effecting the stability of coal mining.
