Coal mine underground drainage system is mainly composed of water pump house sump, drainage pipeline and other parts, and needs to be supported by the power supply system. The drainage system has certain control requirements.
First of all, the mine explosion-proof pump should be replaced in time. For the drainage system, the pump wear is relatively serious, or due to damp failure and other factors, the replacement cycle of the pump is relatively short, so the mine explosion-proof water pump should be replaced in time.
Secondly, stick to the drainage work in the valley section, which can save water pump consumption. Again, strengthen the leakage, flow, and temperature protection of the drainage system to ensure that the drainage system always maintains good performance during work.
In system control, the maintenance work should be carried out through correct working methods. Finally, during the operation of the drainage system, the monitoring of the system should be strengthened, and an early warning system should be set up to ensure that the equipment of the drainage system operates well.
The main drainage mine explosion-proof pump energy-saving and control system consists of five sub-programs, which are automatic pump rotation, pump start, peak avoidance and valley filling, system protection, and work mode switching subprograms. The procedures play an active role in the drainage system to ensure the safe and reliable operation of the drainage system. The continuous influx of groundwater in underground coal mine operations may cause permeation accidents and therefore have higher requirements on the drainage system. The effective work of each subroutine is conducive to improving drainage efficiency and ensuring the safe operation of underground coal mines.
