Abstract
Description
technical field
[0001] The invention belongs to the field of coal mine automation, and relates to a high-efficiency automatic water discharge device for a gas drainage pipeline, which is used for automatic discharge of water stored in the gas drainage pipeline. Background technique
[0002] There is a large temperature difference at various points in the coal mine, so a large amount of condensed water will be formed in the pipeline of the gas drainage system. In addition, because the coal seam and the rock formation inevitably contain moisture, a large amount of borehole water will also be generated during the drilling process and enter the pipeline of the gas drainage system. Condensed water and borehole water existing in gas drainage pipelines affect the normal operation of the gas extraction system, increase the extraction resistance and reduce the extraction effect. Under the condition that the other working conditions remain unchanged, the increase of pipeline accumula...
