深孔CO_2预裂爆破增透技术在突出煤层中的试验与应用

Experiment and application of deep hole CO_2 pre-splitting blast anti-reflection technology in outburst coal seam

为了解决羊东矿突出煤层因煤层透气性低、煤质松软致使的钻孔施工困难、抽采效果差等问题,研究试验液态CO_2深孔预裂爆破增透技术,实践表明,深孔CO_2预裂爆破增透技术有效缩短了工作面瓦斯治理时间,为实现工作面瓦斯抽采达标提供了可靠技术保障,为同类地质条件下瓦斯治理工程提供了借监经验。

In order to solve the low permeability, hard drilling induced by soft coal seam and poor drilling mining effect,deep hole CO2 pre-splitting blast anti-reflection technology was studied, the result showed that the technology shortened the gas control time, provided reliable reference for gas drainage demands and gas control experience under similar conditions.
