摘要
长期以来,为了经济有效的抽采煤层中的瓦斯,顺煤层开采的研究与实践已经取得了突破。然而,在完成抽采任务后瓦斯抽放钻孔就直接废弃,造成很大的浪费。在经济、合理、高效的前提下,曙光煤矿根据具体情况对煤层注水做了相似模拟研究,并且指导了煤层注水的具体实践。结果表明,利用瓦斯抽放钻孔进行煤层注水,不仅可以很大程度上减少钻孔的浪费,而且注水效果非常理想。
To realize economical and effective gas drainage, research and practice of mining along coal seam have made some progress. However, it is wasteful if boreholes are directly discarded after the gas drainage. On the premise of economy, rationality, and efficiency, a simulation study was conducted on water injection in Shuguang mine, which have guided the practice. The results show that using boreholes of the gas drainage to inject water could greatly reduce their waste and the injection effect is ideal.
