摘要
传统的瓦斯抽采技术在糯东煤矿低透气性软煤层中治理瓦斯效果不佳。针对这一问题,在分析水力冲孔卸压增透煤体机理的基础上,在糯东煤矿松软低透煤层进行了水力冲孔现场实践,并初步考察了卸压增透效果。
Traditional gas drainage technology is ineffective in low permeability soft coal seam at Nuodong coal mine. To solve this problem, on the basis of analyzing the pressure relief and permeability incensement for coal by hydraulic flushing, we conducted hydraulic punching field practice in Nuodong coal mine, and preliminary studied the pressure relief and permeability incensement effect.
