The Technology of Multi-Well Hydraulic Fracturing and Controlled Solution Mining for Salt Deposit and Its Application

In this paper, the advantages and shortcomings of the existing solution mining techniques for rock salt deposit are analyzed, the principle and implementing process of multi - well hydraulic fracturing and controlled solution mining technique for rock salt deposit are expounded, and the successful application of this mining technique in the mining of mirabilite in Yuncheng Salt Lake, China, is introduced in detail. The engineering practice proved that multi - well hydraulic fracturing and controlled solution mining for rock salt deposit is a technically feasible method that can effectually control the solution of rock salt and ensure the uniform expansion of dissolving cavity, and can extremely increase the rock salt recovery and the production benefits, thus lower the production cost.
