由兖州矿务局和徐州煤矿采掘机械厂共同研制的ZSP型湿式混凝土喷射机最近通过煤炭部鉴定。该机是1986年研制成功,并于同年4月在修建大秦铁路某一隧道施工中进行了工业性能试验。经对使用的各项指标进行测定后,认为该机工作煤尘浓度已接近国家标准,回弹率低于国家标准,水泥消耗比老式喷射装置大幅度降低,而质量好,强度高,经济效益比较显著,并适用于煤矿井下主巷道的水泥喷凝施工,在煤炭行业很有推广前途。87年8月末,
The ZSP wet concrete jet developed by Yanzhou Mining Bureau and Xuzhou Coal Mining Equipment Factory has recently been identified by the Ministry of Coal Industry. The aircraft was successfully developed in 1986, and in April of the same year in the construction of a tunnel construction Daqin conducted industrial performance tests. After the use of the various indicators were measured, that the work of coal dust concentration is close to the national standard, rebound rate lower than the national standard, cement consumption significantly lower than the old jet, and good quality, high strength, economic benefits More obvious, and suitable for the main roadway in coal mine cement spraying construction, the coal industry is very promising. At the end of August 1987,
