摘要
为解决煤层抽放瓦斯效率低的问题,结合隆博煤矿的工程概况,采用瓦斯孔超长炮孔控制爆破技术法,配合抽放孔封孔技术的改进等措施,以提高煤层透气性。结果表明:该技术大幅度提高了煤矿瓦斯抽放率,大大改善了矿山的瓦斯状况,为矿区大幅度提高煤炭产量奠定了坚实基础。
in order to solve the problem of low efficiency of gas drainage in coal seam,combined with the general situation of Longbo coal mine,the control blasting technology method of gas hole super long blast hole is adopted,combined with the improvement of hole sealing technology of drainage hole,so as to improve the permeability of coal seam.The results show that the technology greatly improves the gas drainage rate of the coal mine,greatly improves the gas condition of the mine,and lays a solid foundation for greatly improving the coal output of the mine.
