摘要
经对阳煤五矿83201工作面施工浅孔高压注水措施,有效降低了工作面割煤期间的粉尘量,使回采期间各工序的瓦斯涌出量相对均匀,增加了各工序的有效作业时间,有效提高了工作面的循环进度。
High-pressure water injection with shallow holes used in 83201 working face in No.5 Mine of Yangquan Coal Group effectively reduces dust during coal cutting,makes relatively even gas emission in each procedure during caving,increases effective operation time,and improves cycle progress of the working face.
