赵城水库下煤炭开采安全性研究
|
摘要
针对永华能源一矿水库下采煤,不但要确保井下安全生产,而且还要保证水库的正常运行运用。首先对该矿22采区赵城水库下压煤工作面回采后上覆岩层破坏高度的分析;然后以采动可能引起的堤体变形破坏、坝体裂缝、动态移动变形这3个方面分析水库下压煤开采对水库安全的影响。结果表明:水库范围内各计算点的导水裂隙带未波及到赵城水库水体,赵城水库下采煤对于井下安全生产是安全的;通过对坝体的移动和变形预计,22采区各工作面回采不会对坝体产生变形破坏;然后计算得出水库下采煤可能引起堤坝裂缝,提出了相应的处理方法。最后针对该采区的地质和采矿条件,提出了工作面合理的回采速度。
Aiming at mining of Yonghua Energy NO.1 coal mine under reservoir,it not only needs to ensure the safety in production,but also needs to ensure the normal operation of the reservoir.First,the damaged height of the overlaying strata was analyzed after coal working face mined under ZhaoCheng reservoir area.And then influence of the mining under reservoir on the reservoir safety was analyzed through the dam deformation failure,dam cracks,dynamic movement and deformation which caused by mining.The results showed that water flowing fractured zone of each calculation point in area of the reservoir did not spread to the Zhaocheng reservoir,so the mining under reservoir was safe.Mining in No.22 mining area would not damage the dam,but might cause dam cracks and the corresponding processing methods was put forward.Finally,according to the geological and mining conditions,reasonable mining speed was proposed.
