AI Technical Summary
Technical Problem
In traditional in-situ leaching uranium mining processes, the pumping system, injection system, and well washing system operate independently, leading to frequent string operations that increase labor costs and switching time.
Method used
An intelligent device integrating pumping and injection in in-situ immersion wells was designed, which has pumping mode, injection mode and well washing mode. The three modes are compatible through pump head short section device, composite pipe and sealing device, reducing the frequency of tubing operation and switching time.
Benefits of technology
It enables seamless switching between different modes, reduces the frequency and time of pipe string operations, lowers labor costs, and improves mine work efficiency and safety.
