Technical Field
The invention relates to the field of comprehensive prevention and control and application of coal mine gas extraction, in particular to a mining air pressure automatic water drainage device.
Background
In the field of comprehensive control and application of coal mine gas extraction, gas and water can be mixed in a negative pressure pipeline, and a large amount of water is gathered at a low-lying position of the negative pressure pipeline to block the pipeline, so that the gas extraction work cannot be carried out. In the traditional method, a water discharger is used for playing a role of automatically discharging water. However, the water discharger has the disadvantages of complex structure, easy blockage, high cost, low efficiency, and the like, and still needs manual operation for water discharge (does not achieve the real automatic water discharge function). If water is not drained timely, the gas extraction efficiency is reduced, the comprehensive control and application of coal mine gas are affected, and huge hidden dangers are brought to coal mine safety.
