摘　　要：针对平煤股份一矿丁5-32080突出工作面回采期间防突及过地质构造问题,采用本煤层顺层钻孔预抽区段煤层瓦斯作为区域防突措施,生产过程中采用了本煤层卸压注水钻孔措施并在过地质构造期间严格执行防突措施。现场实践表明:本煤层顺层钻孔预抽区段煤层瓦斯及本煤层卸压注水钻孔有效地解决了瓦斯异常涌出问题,实现了突出工作面连续6个月安全、稳产、高产。In view of the problem of outburst prevention and geologic structure during the mining of the Ⅳ 5-32080 outburst working face in Pingdingshan No. 1 Coal Mine, the coal seam methane was used as the regional outburst prevention measure in the coal seam predrilling section, and the production process adopted the measures for drilling and pressure-relief of coal seams by using water injection,and outburst prevention countermeasures were strictly implemented when passing through the geological construction. The field practice showed that the coal bed methane gas in the pre-drainage section of the coal bed and the pressure relief and water injection hole in the coal bed effectively solved the problem of gas outflow, and realizes the safety, stable production and high output of the working face with outburst danger for 6 consecutive months.
