摘要
Abstract
In order to solve the problem of high dust concentration in 3308 working face of Guozhuang Coal Industry of Lu'an Group,based on the technology of coal seam water injection and dust reduction,the experimental study of dynamic and static pressure combined water injection and dust reduction in gas extraction hole of working face was carried out.The experimental results show that in the process of coal seam water injection,the closer the distance from the borehole,the greater the water increase,the average water increase rate is 55.6％,and the maximum decrease of dust mass concentration before and after coal seam water injection can reach 78％.The'one-hole dual-purpose'borehole layout and water injection mode can reduce the secondary drilling cycle and investment of coal seam water injection,and achieve certain economic benefits.关键词
