Background technique

my country's coal mining is deeply plagued by gas disasters, and gas has become a major hidden danger to my country's coal mining safety. For the purpose of reducing gas gushing, preventing gas exceeding the limit, and reducing gas accumulation, it is necessary to drill holes in the coal seam, and then use a negative pressure drainage system to extract the gas in the coal seam. However, during the extraction process, for downward drilling, because the coal seam and the overlying strata of the coal seam often contain a large amount of water, due to the effect of the pressure gradient, the water will flow into the borehole and cause water accumulation in the hole. The accumulated water will cause negative pressure damage, affect the drainage effect, and even cause the hole to be scrapped.

Some existing drainage devices have the following problems: 1. Can not automatically drain. There are often hundreds of drainage pipes underground in coal mines, and the workload of manual drainage is very large, which easily makes the drainage untimely. 2. The amount of water in the borehole cannot be monitored, and whether to drain water depends entirely on the experience of the workers, which is highly arbitrary.
