摘　　要：通过鸡西杏花矿生产实践,研究了基于地面立井结合井下钻孔综合抽采回采工作面瓦斯的立体式综合治理技术,给出了合理的抽采技术参数;对地面井的"一井三用"效果进行了考察。项目的成功,解决了鸡西杏花矿低透气性薄煤层瓦斯抽采困难的难题。Based on the production practice of Xinghua mine in Jixi, the three-dimensional comprehensive gas control technology based on the surface shaft combined with the underground borehole is studied, and the reasonable technical parameters of gas extraction are given. The effect of "one well and three applications" in surface well is investigated. The success of the project has solved the difficult problem of gas extraction in the low permeability thin coal seam of Xinghua mine in Jixi.
