The level of automation in underground drainage systems of non-ferrous metal mines in China varies significantly. Most large and medium-sized mines have basically achieved automatic drainage. The automation level of some small and medium-sized mines is still relatively low, and on-site manual operations are mainly performed. Mines that have implemented automatic drainage also have problems such as low degree of automation，independent control systems and inability to share data. The paper describes the current status of the automation of drainage pump house in non-ferrous mines, and proposes the automation transformation solution of the underground drainage pump house based on the SCADA system, and explains in detail the network structure, detection and control content, water pump startup process, and control methods, etc. After the transformation of the underground drainage system, operators can centrally monitor the operation status of all underground drainage pump rooms from the surface control room. This eliminates the “information silos” between the control systems of the various drainage pump rooms, achieving unattended operation of the drainage system. The operational results after the transformation demonstrate significant cost control effects, with labor costs decreasing from $5000/t of copper to $4000/t, resulting in annual labor cost savings of approximately $700000.
