开滦集团钱家营矿自主研发的“煤矿巷道粉尘冲刷装置”近日获得国家实用新型专利。该专利技术有效地解决了井巷粉尘冲刷效率低下、效果不好的问题,具有很强的实用性。开滦集团钱家营矿巷道冲刷以往一直采用传统的“灭尘水嘴+胶管”方式,存在着管路水压低、冲刷速度慢、冲刷周期长、工人劳动强度大等弊端;特别是冬春季节, Kailuan Mining Group camp independently developed “Coal Mine Road dust scouring device ” recently won the national utility model patents. The patented technology effectively solves the problem of low efficiency of dust suppression in the well lane and has poor practicability. Kailuan Group Qianjiaying mine roadway erosion in the past has been using the traditional “Dust Faucet + hose ” way, there is a low water pressure pipe, flushing slow, long erosion cycle, workers and other labor-intensive shortcomings; especially Winter season
