Abstract: Abstract: Jurassic strata characteristics of Hanshuiquan No.3 Mine are introduced in this paper. On the basis of analyzing the formation conditions, rock conditions, fracture conditions and containing water conditions, discusses the groutability of Hanshuiquan mine. Ground pre-grouting design is carried out according to the formation characteristics; and according to the actual situation and grouting parameters, proved the feasibility of surface pre grouting technology in the mining area of the Hanshuiquan
