The conventional single-liquid cement grouting adopted by Gushan Mining Co.，Ltd.，An⁃
hui Masteel Mining Resources Group to block the water-conducting channel of complex water-rich strata
has problems such as poor injectability and slurry diffusion effect. In this regard，Gushan Mining Company
has carried out a high-efficiency inorganic solid water material instead of cement grouting water plugging
test. The results show that the injection of high efficiency inorganic solid water material will form ettringite.
The cost of grouting material is 156.98～228.81 yuan/m3 ，and the cost of grouting stone material is only half
of that of conventional single liquid cement slurry. Compared with the single liquid cement slurry，the high⁃
efficiency inorganic solid water material slurry has the advantages of strong transportability and injectabili⁃
ty，fast consolidation speed，small volume shrinkage after consolidation，and low production cost. The high⁃
efficiency inorganic solid water material has a good promotion and application prospect.
