摘要
在长壁式采煤方法和全部垮落处理顶板条件下,定性分析了开采深度、煤层倾角、开采厚度、工作面斜长、底板抗破坏能力和构造对煤层底板采动导水破坏带的影响。对全国31个实测数据样本,利用灰色关联分析方法进行了定量分析,指出了煤层底板采动导水破坏带深度的主控因素为工作面倾斜长度和煤层倾角。
This paper qualitatively analyzed influence of mining depth,coal-seam dip,mining height,mining face length,anti-broken ability and tectonic on water-conductive fissure zone under long-wall roof-caving mining.Applying gray correlation analysis method to quantitatively analyzing 31 data samples from all over the country,it showed that main controlling factors of water-conductive fissure zone in floor were mining face length and coal-seam dip.
