为解决井下矿山干式喷射混凝土支工艺存在的强度低、物料回弹高、作业粉尘大严重危害喷锚工人身体健康等问题,于八二年四份,在玉泉岭铁矿150M水平对该局一九七八年开始研制的湿式混凝土喷浆机重新进行工业性实验。该阶段试验目的主要是通过大量的喷射,进一步揭露设备矛盾,考验箕斗上料机工作性能与湿喷机配套使用情况,熟练操作,探讨湿喷工
In order to solve the problems of low intensity, high rebound of material and serious serious damage to the safety of spray grouting workers in underground mine dry-jetting concrete branch, in four or eight years in 1982, at the level of 150M at Yuquanling Iron Mine, The wet concrete shotcrete machine started to be developed in 1978 re-run industrial experiments. The purpose of this phase of the test is mainly through a large number of jets, to further expose the contradictions of equipment, test skip skipper working performance and wet jet matching the use of equipment, skilled operation, wet spray
