为解决潮喷工艺中粉尘浓度大、回弹率高和目前湿喷技术存在配套系统复杂、工人劳动强度大等难题,介绍了一种可以实现煤矿巷道喷浆支护安全高效、绿色环保生产的新型湿喷装备,分析了机组可以取得每米喷浆进尺共节约375.9元的经济效益。结果表明:该技术满足煤矿井下巷道湿式喷浆要求。
In order to solve the problems of large concentration of dust, high rebound rate and the complex system of wet spraying technology, and the labor intensity of workers in the tidal spraying process, a method that can realize the safe and efficient green production of coal mine shotcrete supporting is introduced. New wet spray equipment, analysis of the unit can be achieved per meter shot into a total cost savings of 375.9 yuan economic benefits. The results show that the technology meets the requirements of wet shotcrete in coal mine tunnel.
