摘要
针对目前"干式"钻孔的问题,提出并研制了旋转磨料射流钻孔装置。它能有效提高钻孔速度,降低钻孔过程中出现的着火、喷火等现象的几率,降低煤尘浓度,从而改善工人的工作环境,解决"干式"钻孔出现的问题。
In view of the present ＂dry＂ drilling＇s problems, developed a rotary abrasive jet drilling device. It can effectively improve the speed of drilling,reduce the probability of fire,spray fire appeared in drilling, reduce dust concentration and improve workers＇ working environment,and solve the problems of ＂dry＇drilling.
