摘要
通过对煤层裂隙井下实地观测和统计分析,总结了古汉山煤矿二1煤层宏观裂隙的发育特征和分布规律。根据裂隙发育优势方位,优化布设钻孔,有助于提高瓦斯抽采效果。
Through observation and statistical analysis of underground coal seam underground fissure, summarizes the development features and distribution rules of Guhanshan coal mine two coal seam 1 macro crack. According to the position of fracture development, optimized layout drilling, improve gas drainage effect.
