Abstract

The invention provides an in-situ leaching instantaneous high-pressure gas pulse fracture forming system and a using method thereof, and belongs to the technical field of leaching mining. The in-situleaching instantaneous high-pressure gas pulse fracture forming system comprises an air storage tank, an air compressor, a pressure gauge, a one-way valve, sealants, a pulse controller, a steel pipe,a pressure sensing optical fiber instrument and a data collection system. The air storage tank is connected with the air compressor, air in the air storage tank is input into the air compressor to becompressed, the one-way valve is located at the joint of the air storage tank and the air compressor to prevent air backflow, the pressure gauge is located on the outer side of the device and connected with the air compressor, the pulse controller is connected with the air compressor to generate physical shock waves and control air pulses to impact an ore body, and the sealants are located at thejoint of the pulse controller and the pressure sensing optical fiber instrument to prevent gas leakage. The in-situ leaching instantaneous high-pressure gas pulse fracture forming system is reasonablein structure, convenient to use and capable of effectively increasing gap channels in the in-situ leaching mining process, so that ore leaching liquid makes more sufficient contact with ore, and helpis provided for improving the in-situ leaching efficiency.

Description

technical field [0001] The invention relates to the technical field of leaching mining, in particular to an in-situ leaching instantaneous high-pressure gas pulse fracture-making system and a use method thereof. Background technique [0002] In-situ leaching refers to injecting the solution from the surface into the deep ore body through the liquid injection drilling. During the flow of the solution in the ore body, the leaching reaction with the target mineral occurs, and the obtained soluble metal ions enter the solution, and the solution is discharged through the pumping hole. Elevate to the surface, and finally obtain metal products through extraction-electrowinning process. This technology can realize unmanned underground operation, avoid environmental damage caused by ore body excavation, and has the characteristics of high safety, low pollution and low cost. Among them, the flow process of solution in the ore body is the core of the whole leaching process, and the st...
