Problems solved by technology
At present, the non-contact early warning methods proposed for coal and gas outburst include microseismic monitoring and early warning, acoustic emission monitoring and early warning, electromagnetic radiation monitoring and early warning, charge induction prediction, and coal infrared temperature detection. Infrared temperature detection usually uses thermometers, infrared sensors, etc. Thermal imaging detects coal body temperature, but the false alarm rate and false alarm rate are still high, which is difficult to meet the needs of coal mine safety production

The present invention provides a coal and gas outburst early warning system and method based on infrared thermal images, the system includes a monitoring host, a data server, a DLP screen, a first switch, a second switch, and a data acquisition module for a coal face The data acquisition modules of each coal mining face include a serial port server, a DAQ data acquisition unit, N thermal imaging sensors, M temperature sensors, and a methane sensor; the method is based on the gas concentration value, The temperature field gradient change matrix of the infrared thermal image, the temperature gradient value of adjacent points of the infrared thermal image, and the gray scale difference matrix of the infrared thermal image Analyze the changing state of the temperature field distribution in the image, and judge the risky state, and send out alarm signals and low early warning signals; effectively avoid gas outburst accidents and reduce casualties and economic losses.
Description
technical field [0001] The invention belongs to the technical field of mine gas monitoring safety, and in particular relates to a coal and gas outburst early warning system and method based on infrared thermal image in coal mining face. Background technique [0002] Coal plays a major role in my country's primary energy consumption. Coal and gas outbursts are one of the primary factors restricting the safe and healthy production of coal enterprises in my country. With the increase of coal mine mining depth, coal and rock outbursts and other coal-rock dynamic disasters are becoming more and more serious. The danger of outbursts is increasing, and the intensity and frequency of outbursts are gradually increasing. Therefore, it is very important to prevent coal and gas outburst dynamic disasters. [0003] Coal and gas outburst is an extremely complex dynamic disaster phenomenon of gas-containing coal bodies. With a strong sound, this phenomenon occurs in a short time (tens of s...
