摘要： 为了解决玉溪煤矿煤层瓦斯抽采过程中遇到的问题，结合煤层瓦斯赋存条件，采用水力压裂增透技术进行相
关处理。处理效果显示，瓦斯压力、瓦斯含量降到临界值以下，实现了区域消突；抽采半径显著增大，钻孔工程量减少
50%以上；掘进期间，各项防突指标未出现超限等异常情况，瓦斯浓度大幅度降低，掘进速度大幅度提高。

Abstract: In order to solve the problems encountered in the gas drainage of Yuxi Coal Mine, combined with the gas storage
conditions of the coal seam, the hydrofracturing technology for enhancing permeability was used for the relevant treatment. The
results showed that the gas pressure and gas content were below the critical value, and the regional outburst control was realized;
the extraction radius increased significantly, and the amount of drilling work reduced by more than 50%; during the excavation,
the outburst prevention indexes did not exceed the limit and other abnormal conditions, the gas concentration was greatly reduced,
and the excavation speed was greatly increased.

Key words: gas extraction; hydrofracturing technology for enhancing permeability; fracturing borehole; gas concentration
