摘要
结合东曲煤矿九采区上组煤煤层赋存、分布规律、瓦斯地质特征和生产技术条件,优化选择底板岩巷穿层钻孔消突技术,配套使用水力造穴增透技术,提高了煤层的透气性和瓦斯抽采效果,有利于防治高突区域内煤与瓦斯突出难题。
Combining the occurrence and distribution of upper coal seams,gas geological characteristics and production technical conditions of the upper group of coal in the 9th mining area of Dongqu coal mine,the technology selection is optimized as floor rock drilling for the gas outburst elimination,together with the use of hydraulic cave-making to increasing permeability.The practice improves both the permeability of the coal seam and gas drainage,which is conducive to the prevention and control of coal and gas outbursts in high outburst areas.
