顺层长钻孔水力压裂增透技术在煤层瓦斯抽采中的应用

摘要

阳煤集团新景公司通过实施井下顺层长钻孔水力压裂增透技术，实现了对碎软煤层瓦斯远距离与区域增透抽采，有效解决了煤层透气性差、瓦斯抽采孔成孔性差、抽采距离短、抽采区域小等难题，大幅提高煤层瓦斯预抽率和抽采量，降低了3#煤层开采过程中的突出危险性，为阳煤集团安全高效开采、瓦斯治理降本增效等方面提供了可靠的技术保障。%Yangquan Coal Group XinJing Company through the implementation of the long borehole along the seam hydraulic fracturing technology to increase permeability, realized the long distance gas drainage in the broken soft coal seam, which effectively solve the problems, such as the poor coal seam permeability, the dififcult holing, the short drainage distance, the small drainage area, substantially increased the coal seam gas drainage rate and drainage quantity, and reduced the outburst danger of 3# coal seam in the process of mining, it provides reliable technical support for safe and efifcient mining, cost decreasing and beneift increasing in the gas governance of Yangquan coal.
