Technical Field
The utility model belongs to the technical field of colliery gas drainage, concretely relates to automatic sediment device of arranging of gas drainage pipeline hydraulic drive.
Background
The geological structure and coal bed occurrence conditions of coal mines in China are relatively complex, more than 50% of the currently mined mines are high-gas or coal and gas outburst mines, wherein the coal and gas outburst mines are 757 and the high-gas mines are 1024. Eighty-five rules of coal mine safety (2016) specify: the gas emission quantity of the outburst mine is more than 3m before the outburst coal seam is exposed and on any tunneling working face during the well building process3And min, solving the unreasonable gas problem by using a ventilation method, and establishing a gas extraction system. Meanwhile, the eighteenth regulation of the Fine rules for preventing coal and gas outburst (2019): the outburst mine must establish a ground permanent gas extraction system. According to the specified requirements, all the existing high-gas and coal and gas outburst mines in China establish gas extraction systems, but the research finds that the actual average gas extraction rate of most of the high-gas and coal and gas outburst mines in China is only 23%.
At present, the low gas extraction rate of a mine is mainly influenced by various factors: coal bed permeability, system grid connection, hole sealing quality and cinder blockage. The blockage of the coal cinder is caused by the fact that a large amount of coal cinder from a coal rock layer enters a gas extraction pipeline under the combined action of gravity and negative pressure in the actual extraction process of mine gas and is mixed in a negative pressure gas flow to move forwards along with the coal cinder, and the coal cinder stays at the lower part of the pipeline due to the mutual friction effect with the inner wall of the extraction pipeline in the transportation process, so that the effective extraction section of the pipeline is sharply reduced, and the gas extraction effect is seriously influenced. Therefore, the sixteenth and seventeenth provisions of the provisional provisions for meeting the standard of coal mine gas extraction are as follows: a deslagging device is arranged in the gas extraction pipe network when necessary, so that the coal slime is prevented from blocking the section of the pipeline.
Therefore, aiming at the technical problem that the average extraction rate of actual gas is caused by the blockage of coal slag in high-gas mines and coal and gas outburst mines at present, the deslagging device suitable for the negative pressure environment of the gas extraction pipeline under the coal mines is developed, the coal slag is rapidly removed, the gas extraction efficiency of the mines is improved, and the deslagging device has very important significance.
