What is the purpose of the mine drainage system diagram?

The purpose of the mine drainage system diagram: Intelligent strong drainage system drainage can transform post-disaster relief into prevention in advance. The drainage system always runs in a non-accident state, moving the accident node forward to ensure the safety of human life and property. . Practice has proved that this system has played a key role in the rescue work of many major water damage accidents, achieved the expected purpose, and received good results.

With the rapid development of economy. As the country's basic energy source, coal mine construction has rapidly entered into large-scale and intensive processes. A new phase of automation. According to the "Coal Mine Safety Regulations", in order to ensure the safety of life and property in mining areas, in view of the special and complex geological conditions and production environment of typical mining areas or mines with the risk of water inrush and flooding, a drainage system with matching scale and independent characteristics compared with other normal drainage systems should be constructed. Intelligent and integrated safe and strong drainage system.

Mine water leakage accidents are catastrophic accidents with the greatest harm, widest impact, longest period, and difficulty in rescue. Coal mines, iron ores and non-ferrous metal ores. Non-metallic mines are areas with a high incidence of water penetration accidents. The national safety supervision and coal departments attach great importance to the prevention and control of mine floods. After years of fighting against mine floods, they have summarized and vigorously changed the strategies for disaster prevention, water control and disaster relief. Changing the post-processing strategy of emergency and disaster relief to a strategy based on prevention and control, drainage and drainage to improve the ability to prevent and control floods and increase the opportunities for people to escape in flood situations fully embodies the people-oriented concept. Achieve a combination of prevention and treatment, focusing on prevention. Even in the event of a water penetration incident, there is enough time to evacuate personnel and save critical equipment. At the same time, it is required to actively promote the intelligent safe drainage system of unattended and remote monitoring and centralized control of underground pump rooms.

Design basis:

System design principles:

1) To meet drainage needs in the event of danger. There is enough time for evacuating personnel to save critical equipment. The water pump can be started on the ground and the status of the water pump can be monitored. It has an independent power supply system and does not interfere with other equipment.

2) Automatic drainage monitoring and alarming of water tanks are realized through optical cable transmission. The water storage warehouse implements automatic control and automatic detection of operating parameters, remote control, dynamic local display and transmits data information to the ground production dispatch center and production equipment control center for real-time monitoring, alarm display, fault history query and report printing.

3) The system detects parameters such as motor current and motor voltage. Monitor the working status of the water pump, intuitively and vividly reflect the working status of the system in real time and control it.

4) Realize the access to parameter interfaces such as water tank water level, water pump temperature, and drainage pipe flow, as well as the control interface output of the electric gate valve.
