Abstract: The ending point of leaching is related to the economic benefits of in-situ leaching, as well as the automation and digital construction of mines.Firstly, the limitations of the conventional method of the ending point are discussed.The reasons why the pumping units in the same mining area cannot achieve the best production status at the same time are analyzed.The variation law of the investment income of in-situ leaching with time is summarized.The pumping unit and the shortest production period is the basis for calculating the ending point of in-situ leaching.Then, the various indicators affecting the production cost of in-situ mining are analyzed, and a new method for calculating the ending point is established.Finally, taking the mining test area of in-situ uranium leaching as an example, the data of production cost is counted, the economic benefit of each pumping unit is judged by the new method, and the countermeasure analysis of the production is proposed.
