摘　　要：以地面钻井抽采上覆远距离煤层卸压瓦斯原理为基础,对淮南潘一矿地面钻井抽采上覆远距离煤层卸压瓦斯技术进行了试验研究。试验结果表明,在开采下保护层的同时配合上覆远距离被保护煤层的地面钻井瓦斯抽采,能有效降低上覆远距离被保护煤层的瓦斯含量,提高下保护层对上覆煤层的有效保护高度和保护效果。该技术对同类型矿区中低透气性、高瓦斯上覆远距离突出煤层的瓦斯抽采和突出防治具有一定的借鉴和指导意义。Based on the theory of pressure-relieved gas drainage and extraction from the overlying long-interval protected seam by surface boreholes,test study was made on the pressure-relieved gas drainage and extraction technology from the overlying long-interval protected seam by surface boreholes in Panyi Coal Mine. The test results showed that while the lower protective seam was extracted,the application of pressure-relieved gas drainage from the overlying long-interval protected seam could effectively reduce the gas content of this seam and improve its effective protective distance and effect. This technology has important guiding and reference significance for the prevention and control of gas outburst and gas drainage from the overlying high-gassy long-interval outburst seam with low gas permeability.
