Abstract

The invention provides a uranium mine carbon dioxide blasting and carbon dioxide and oxygen in-situ leaching mining test device, which comprises a sample sealing unit, a blasting unit, a leaching unit, a liquid injection unit, a hydraulic regulation and control unit, an air pressure regulation and control unit and a detection unit, and is characterized in that the sample sealing unit is used for accommodating and sealing a sample of a sandstone uranium mine; the blasting unit is communicated with a sample in the sample sealing unit; the leaching unit is communicated with the sample sealing unit; the liquid injection unit is communicated with the sample sealing unit; the hydraulic regulation and control unit is communicated with the sample sealing unit; the air pressure regulation and control unit is communicated with the sample sealing unit; the detection unit is communicated with the sample sealing unit. The uranium mine carbon dioxide blasting and carbon dioxide and oxygen in-situ leaching mining test device provided by the invention aims to realize real simulation of blasting and in-situ leaching mining processes of sandstone uranium mine, and deeply study the crack initiation extension law of sandstone uranium mine blasting cracks, the permeability evolution law of blasting ore beds and the reaction flow law of fractured rock mass leaching liquid.

Description

technical field [0001] The invention belongs to the technical field of geological mining, and more specifically relates to a test device for uranium ore carbon dioxide blasting and carbon dioxide and oxygen leaching mining. Background technique [0002] Uranium is an important natural radioactive element and the most important nuclear fuel. As an important national strategic resource and energy mineral, uranium plays an important role in national defense construction and economic development. With the increasing difficulty and depth of uranium resource mining, the permeability of sandstone uranium deposits gradually decreases, and low permeability has become a key factor restricting uranium mining. [0003] Through blasting, a three-dimensional fracture network can be formed inside the uranium ore layer, which can significantly improve the overall permeability of the uranium ore layer. CO 2 +O 2 Neutral in-situ leaching has little impact on the groundwater environment, an...
