One-hole and one-measurement monitoring device for coal mine drill site extraction and detection method of one-hole and one-measurement monitoring device

Abstract

The invention discloses a coal mine drill site extraction one-hole one-measurement monitoring device which comprises a fixed shell, the fixed shell is of a rectangular box body structure, a busbar is arranged at the opposite position of the bottom side in the fixed shell, a plurality of air inlet quick connectors are installed at the bottom of the busbar, and the air inlet quick connectors downwards penetrate through the bottom of the fixed shell; the gas inlet quick connectors are located on the outer side of the fixed shell, a plurality of electromagnetic valves are installed on the top of the busbar, the number and the position of the electromagnetic valves correspond to the number and the position of the gas inlet quick connectors, and the gas inlet quick connectors are controlled by the electromagnetic valves to be opened and closed. A vacuum pump for providing power for gas entering the gas main pipe is arranged at the top end of the gas inlet main pipe, the vacuum pump is communicated with a gas conveying pipe, and a gas detection module is arranged at the right end of the gas conveying pipe. The beneficial effects of the invention are that the cost can be saved, and the detection precision and efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of gas mining, and in particular relates to a one-hole-one-measurement monitoring device and a detection method for coal mine drilling site drainage. Background technique [0002] The situation in the coal mine is complicated, and it is necessary to detect various gases in the coal mine. The current detection of the concentration and pressure parameters of the coal mine borehole mainly relies on manual inspection in a portable way. parameters, and then go to the next borehole to measure the data of the next borehole. Due to the large number of boreholes in the coal mine, it consumes a lot of manpower, and the real-time performance of the data is poor; if the measurement is installed near each borehole Sensors cost too much; so there are a lot of missed inspections and frauds in the actual operation process, which is not conducive to the safety management of coal mines; specific shortcomings include: 1.

[0002] The situation in the coal mine is complicated, and it is necessary to detect various gases in the coal mine. The current detection of the concentration and pressure parameters of the coal mine borehole mainly relies on manual inspection in a portable way. parameters, and then go to the next borehole to measure the data of the next borehole. Due to the large number of boreholes in the coal mine, it consumes a lot of manpower, and the real-time performance of the data is poor; if the measurement is installed near each borehole Sensors cost too much; so there are a lot of missed inspections and frauds in the actual operation process, which is not conducive to the safety management of coal mines; specific shortcomings include: 1. Due to the large number of drill holes in each coal mine, the manpower and material resources spent on inspections Very large; 2. The detection method is single, currently mainly based on portable methods, and the data is not continuous; 3. Due to the large number of drilling holes, it is easy to cause missed detection and fraud, which is not conducive to the safety management of coal mines; 4. The inspection cycle is long and not timely. 1. The real-time performance is poor, and the danger cannot be warned in time; 5. If concentration monitoring is installed in each borehole, the cost of equipment will be particularly huge; 6. At the same time, due to the unevenness of personnel, safety management is difficult; for this reason, people are always looking for a solution
