目前注浆堵水已成为治理煤矿地下水害行之有效的方法之一。但注浆所用的设备全系其他设备代替。除搅拌压浆是机械化施工外,其余全靠人工进行,大量水泥包要人工装卸、搬运,特别是单位时间的注浆量比较大时,要求在短时间内将几十吨至上百吨水泥制成浆液,不但劳动强度大,而且直接危害工人的身体健康。因此,研究新的造浆系统,成为注浆工作的迫切需要。我们从一九七五年开始研制风动造浆系统,用了不到一年的时
At present, grouting water blocking has become one of the effective methods to control groundwater damage in coal mines. However, grouting equipment used in the whole system instead of other equipment. In addition to mixing grouting is mechanized construction, the rest rely entirely on the manual, a large number of cementing bags to be manually handling, handling, especially when the grouting amount per unit time is relatively large, requiring a few days in the tens of tons to 100 tons of cement Into a slurry, not only labor-intensive, but also directly endanger the health of workers. Therefore, researching new slurrying systems has become an urgent need for grouting work. We started to develop the wind-driven slurrying system from 1975 and took less than a year
