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。 The traditional gas drainage technology in Wandong coal mine low permeability gas coal seam in poor governance. In response to this problem, based on the analysis of the mechanism of hydraulic piercing and pressure-reducing pervious coal, the practice of hydraulic punching in soft and low permeability coal seam of Wandong coal mine was carried out, and the effect of pressure relief and permeation enhancement was preliminarily investigated.
