杏花煤矿现主采煤层为28＃3、0＃两层煤，下覆煤层组渗析的瓦斯导致28＃工作面产能得不到释放，为解放28＃采面生产力，在30＃煤层内打覆盖钻孔，形成瓦斯屏蔽层，对50米范围内的下覆煤层组30＃、31＃、34＃、35＃、36＃的瓦斯进行屏蔽，此技术的应用试验在杏花煤矿取得了良好的效果。

The main coal seams of Xinghua Coal Mine is 28#,30#layers of coal mine .Gas emission from overlying coal seams limits the capacity of production in the seam 28#.In order to improve the productivity in the seam 28#, it is necessary to arrange e-nough gas drainage boreholes in the seam 30#to form a gas shield.The gas from coal seams 30#,31#,34#,35#,36#within 50 me-ters would be shielded .The application of this technique in Xinghua Coal Mine has achieved good results in solving the percolation of gas.
