In domestic mining companies, the existence of water hazard not only increases the cost of mine production, but also is a direct threat to the miners’safety underground, especially in the mine with complex conditions such as big depth, high water temperature, etc. Therefore, improving the running efficiency and reliability of the mine drainage system has become an important issue for mining companies. According to the actual situation of a mine, an optimal design of the mine drainage system under complex conditions, and propose solutions for the common problem of the underground drainage system such as water hammer, cavitation, etc. are given in this dissertation. On the purpose of maximizing the efficiency of the entire drainage system, pumps of the pumping station and pipelines type should be integrated designed, and the best operating point can be chosen according to the characteristics ofmain drain pumps and pipelines. In response to the section 118 provisions of “Mine Water Prevention and Control Regulations” ulated by State Administration of Work Safety Supervision, the pumping station automatic control and remote monitoring system is designed to deal with cumbersome operation, labor intensity and low efficiency of system operation, etc. The system achieves centralized control of the underground drainage pumps，related data in real-time display and alarm function with Siemens S7-300 series PLC and the associated sensor technology. The connection to Industrial Ethernet, which allows the ground-based data centerto monitor and control drain pumps underground. With modular programming techniques of PLC, the rotation of the pump system and “off-peak and valley-filling“ of electricity is achieved, which improves the efficiency of the system and reduces the running costs of the system. The main drainage system is optimized according to the specific conditions of the mine in this paper. The automatic control and remote monitoring capabilities significantly improve efficiency and reliability of the system, which laid a good foundationto the digital mines and achieved good economic and social benefits.
