摘要
介绍了一号煤矿603采煤工作面进行高位裂隙钻孔瓦斯抽放的机理及抽放钻场、钻孔的布置,并利用近水平煤层单层开采时采厚与两带高度关系图参考和分析钻孔的抽放效率及抽放效果,为提高和优化瓦斯抽放参数提供依据,有效消除了设计中的盲目性和人为失误。
The paper introduced the layout of drilling field and borehole which for gas drainage by high level fracture borehole, analyzed the relationship between mining height and ＂two zones＂ height in near horizontal seam mining. The research can provide basis for optimizing gas drainage parameter design, improving drainage emciency and drainage effect and eliminating blindness and human error in design.
