  • RAPID MINING METHOD FOR SANDSTONE-TYPE URANIUM RESOURCES IN URANIUM AND COAL SUPERPOSED AREA
    Publication number: 20240191608
    Abstract: A rapid mining method for sandstone-type uranium resources in a uranium and coal superposed area, which relates to the technical field of mining engineering is provided. The method includes: arranging a high-density adjustable well pattern in an in-situ leaching mining area; determining a length and a position of a filter located on the in-situ leaching mining area through a digital well construction technology; and in a production stage, carrying out operations such as pumping/injection centralized filtration, intensified leaching, high-intensity extraction, high-intensity injection, and change of layout of the high-density adjustable well pattern to rapidly obtain sandstone-type uranium resources in a uranium and coal superposed area. A recovery speed of the sandstone-type uranium resources can be improved, and service life of the in-situ leaching mining area can be shortened.

  • In-situ leaching mining method and system
    Patent number: 11174717
    Abstract: The present invention discloses an in-situ leaching method and system. The ISL mining method provided by the present invention includes: constructing a vertical guiding well into an ore body; constructing a horizontal well towards the vertical guiding well, where the horizontal well includes a vertical section and a horizontal section; one end of the horizontal section is connected to the vertical section, and the other end of the horizontal section is connected to the vertical guiding well; constructing a plurality of vertical extraction wells towards the horizontal section; and simultaneously injecting lixiviant into the vertical section and the vertical guiding well by means of pressurized injection, and extracting leachate through the vertical extraction well. The ISL mining method and system provided by the present invention accomplish the injection through a horizontal well.
