Description

Technical Field

[0001] The utility model relates to the technical field of pressure detection, in particular to a mine pressure detection device. Background Art

[0002] Coal has always occupied a dominant position in my country's energy consumption structure. With the increasing depth of coal mining, coal and gas outburst disasters in underground production are becoming more and more serious. Coal and gas outburst is a very complex mine gas dynamic phenomenon in underground coal mine production; the occurrence of coal and gas outburst is mainly the result of the combined action of ground stress, gas pressure and the physical and mechanical properties of coal body; because coal and gas outburst is accompanied by gas explosion, coal dust explosion and other disasters, it may destroy the entire working face and even the entire mine. Therefore, coal and gas outburst poses a serious threat to coal mine safety production.

[0003] Among them, coal seam gas pressure is one of the main parameters for identifying the danger of mine outburst. With the popularization of intelligence in the mining industry, the commonly used monitoring equipment in coal mines is developing in the direction of intelligence. At present, the pressure detection of coal mines is mainly completed by the grating module located in the coal seam and the rock formation in conjunction with the pressure signal transmitting mechanism connected thereto. During the detection process, the grating module in the coal seam and the rock formation transmits the detection data to the pressure signal transmitting mechanism, and then transmits the detection data through the pressure signal transmitting signal. This method effectively avoids the problem of a large workload caused by the need for a large number of personnel to read the display data of the pressure testing instrument. At the same time, it can display the value of the coal seam gas pressure in real time and realize the continuous monitoring of the coal seam gas pressure. However, the problems it has are:

[0004] When the real-time dynamic transmission of pressure is realized through this signal transmission system, it is difficult to achieve high adaptability for drilling positions of different depths, and it is not possible to perform real-time detection operations according to different depth positions. The sealing performance needs to be improved. During the detection process, affected by the pressure at different depths, a small amount of gas is likely to leak out along the channel of the signal transmission optical cable, which will lead to inaccurate detection results.

[0005] Therefore, the utility model proposes a mine pressure detection device. Utility Model Content
