为了贯彻执行《煤矿安全规程》的有关规定,搞好综合降尘,我矿建立了防尘静压水管路系统,工作面实行煤层注水、水炮泥、喷雾洒水、通风巷道喷雾净化风流等措施、然而煤巷掘进工作面和回采工作面的煤尘浓度仍然达不到国家卫生标准。而工作面电钻打干眼是生产作业中产生煤尘最突出的一个问题。为此,我们对煤电钻湿式钻孔进行了研究和试验。主要是将麻花钻杆的结构进 In order to implement the relevant provisions of the “Coal Mine Safety Code,” and do a good job of integrated dust control, mine set up a dust-proof static pressure water pipeline system, the face of the implementation of coal seam water injection, water cannons, spray water spray, However, the coal seam excavation face and mining face of coal dust concentration is still less than the national health standards. The face drills eye drills is the most prominent issue in the production of coal dust. For this reason, we have carried on the research and the test to the coal drill wet drilling. Mainly twist the structure of the drill rod into
