A multi-parameter and multi-measuring point monitoring device for coal mine gas disasters

Abstract

The invention relates to a coal mine gas disaster multi-parameter and multipoint monitoring device. The device is characterized by comprising a gas pressure monitoring device, a drill hole stress monitoring device, a gas concentration monitoring device, a plurality of monitoring sub stations, a monitoring branch station and a ground terminal. The gas pressure monitoring device is arranged in a first drill hole of one side of a roadway, the drill hole stress monitoring device is arranged in a second drill hole of the other side of the roadway, and the gas concentration monitoring device is suspended on the top plate of the roadway; the gas pressure monitoring device monitors the gas pressure signals in real time and transmits to a first monitoring substation; the drill hole stress monitoring device monitors the drill hole stress signals and transmits to a second monitoring sub station; the gas concentration monitoring device monitors the gas concentration signals of an operation space in real time and transmits to a third monitoring sub station; the first, second and third monitoring sub stations transmit the signals to the monitoring branch substation by the wireless communication technology, and the monitoring branch substation transmits all monitoring signals to the ground terminal through an optical fiber. The device can be widely applied to predication of coal and gas outburst and rockburst of coal mine.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a multi-parameter and multi-measuring point monitoring device for coal mine gas disasters. Background technique [0002] In recent years, my country's gas disaster accident control has achieved remarkable results, but with the increase of mining depth, the number of high gas outburst mines has increased significantly, and the difficulty of gas control has become more and more difficult. Coal mine gas outburst disaster monitoring and early warning has become an important research direction for coal mine safety production . [0003] The existing methods for preventing gas disasters are mainly through manual determination of parameters, establishment of judgment models, manual implementation of preventive measures and effect testing. Since this method mainly relies on manual extensive supervision and supervision, it has the following disadvantages: less monitoring parameters, less information ...

Problems solved by technology

[0003] The existing methods for preventing gas disasters are mainly through manual determination of parameters, establishment of judgment models, manual implementation of preventive measures and effect testing. Since this method mainly relies on manual extensive supervision and supervision, it has the following disadvantages: less monitoring parameters, less information Small quantity, low accuracy of information, poor timeliness, lag in judging hazards, reliability of judging is highly dependent on the technical management level of the judging person, and dangers rely on manual emergency response, improper handling can easily lead to major accidents, etc.

Therefore, the current methods of preventing gas disasters are difficult to achieve the expected goals in terms of procedures, methods and effects
