摘　　要：本文以漳村煤矿瓦斯抽采工作为研究对象,通过分析钻孔布置方式对应的抽采瓦斯浓度变化,提出了高位钻孔布置参数优化方案。试验结果表明,采用高位钻孔布置参数优化方案在仅增加73%的钻孔工程量的情况下,抽采瓦斯总量就能够增加3~7倍,更加有效地降低了工作面的风排瓦斯涌出量。This paper takes Zhangcun Coal Mine gas drainage work as the research object,through the analysis of borehole layout corresponding to the change of gas concentration,put forward a high-level borehole layout parameter optimization program.The test results show that the total amount of gas drainage can be increased by 3~7 times,and the amount of gas emission can be reduced more effectively when only 73%of the total amount of drilling work is increased.
