Abstract

The invention provides a mine gas extraction and outburst elimination processing system. The system comprises a collection sub-system, a gas pressure monitoring sub-system, a low-flow single-pore automatic metering sub-system, a coal bed expansive deformation monitoring sub-system and a drainage amount control sub-system, wherein the collection sub-system is used for collecting a pressure value of mine gas, a drilling site flow rate of an extraction drilling site, expansive deformation of a coal bed and a water level value of a drainage device; the gas pressure monitoring sub-system is used for acquiring the extraction radius according to the pressure value of the mine gas; the low-flow single-pore automatic metering sub-system is used for acquiring the drill hole flow rate of an extraction drill hole according to the drilling site flow rate of the extraction drilling site; the coal bed expansive deformation monitoring sub-system is used for acquiring the expansive deformation rate of the coal bed according to the expansive deformation of the coal bed; and the drainage amount control sub-system is used for controlling drainage according to the water level value of the drainage device. According to the embodiment of the invention, data can be automatically collected, a gas extraction metering daily report and variation curve can be recorded and generated, and the data is continuous, so that the data variation trend can be intuitively analyzed.

Description

technical field [0001] The invention relates to the technical field of mine drainage, in particular to a mine gas drainage and outburst elimination data processing system. Background technique [0002] The key task of coal mine gas control work is the outburst prevention work. According to the "Regulations on the Prevention and Control of Coal and Gas Outburst" promulgated by the State Administration of Work Safety, the important indicators for judging the risk of coal seam outburst are coal seam gas pressure and gas content. The main purpose is to eliminate the risk of coal seam outburst (that is, outburst elimination). The main measures are protection layer mining and regional pre-drainage. The evaluation parameters of the outburst prevention effect are mainly residual gas pressure, gas content and coal seam expansion and deformation coefficient. [0003] At present, the measurement method used in China is manual measurement, which is time-consuming and labor-intensive, th...
