Environment-friendly water-holding coal and uranium coordinated mining system and application method thereof

Abstract

The invention discloses an environment-friendly water-holding coal and uranium coordinated mining system. The environment-friendly water-holding coal and uranium coordinated mining system comprises a freezing mechanism, a pumping and injecting mechanism, a water storage mechanism and a mining supporting mechanism. The freezing mechanism is provided with freezing shafts. The pumping and injecting mechanism is provided with fluid injecting wells and a fluid pumping well. The water storage mechanism is provided with an underground reservoir, a security coal pillar and advance water discharge pipes. The mining supporting mechanism is provided with a road header, a coal mining machine, a scraper conveyor and a hydraulic support. The freezing shafts in the freezing mechanism conducts freezing on an aquifer on the periphery of the pumping and injecting mechanism with the pumping and injecting mechanism as the radius; the pumping and injecting mechanism conducts uranium mining by an in-situ leaching technology; the mining supporting mechanism conducts stoping on a coal seam; and the water storage mechanism stores and purifies water in the aquifer of a broken roof. Finally, under rational cooperation of the four mechanisms, coal and uranium coordinated mining is realized, underground water is recovered and purified at the same time, and the purpose of environment-friendly water-holding multi-resource coordinated mining is achieved.

Description

technical field [0001] The invention relates to a green water-retaining coal-uranium coordinated mining system and a method for applying the system. Background technique [0002] The Ordos Basin is rich in resource reserves, and a variety of precious resources are vertically stacked together. In order to coordinate the exploitation of multiple resources in time and space, various universities and scientific research units have actively discussed. However, there is still no reasonable and feasible coordinated mining plan, and the coordinated mining of coal and uranium is even more difficult to solve. The reaction liquid of uranium in-situ leaching mining will invade into the coal seam mining area, resulting in waste of coal seam. Disturb the overlying aquifer and uranium layer, resulting in waste of uranium and water resources. Based on the above situation, there is an urgent need for a green water-retaining coordinated mining system for coal and uranium, which can realize t...
