Coal and gas outburst real-time early warning device and method based on multi-source information fusion

Abstract

The invention discloses a coal and gas highlight real-time prewarning method based on multi-source information fusion. The coal and gas highlight real-time prewarning method comprises the following steps that an advanced knowledge base is built up; judging criteria of a highlight dangerous single index are built up; various highlight dangerous prediction information is collected; multi-level fusion is conducted on the collected various information; real-time evaluation and level early prewarning of dangerousness are highlighted; and the dangerousness prevention is highlighted. According to thecoal and gas highlight real-time prewarning method, aiming at different characteristics of difference and prediction methods of highlight sensitive indexes represented by highlight dangerousness in different mines, after diagnosis evaluation is conducted on equipment monitoring and manual inspection detection information based on highlight omens from different information sources, real-time prediction of multi-source information fusion is conducted by utilizing an information fusion theory and a time-space coupling mechanism, so that precise prewarning information is provided, the wideness and real-time performance of collection of omen information before highlight happening are improved, and the accuracy of highlight dangerousness prediction is improved greatly.

Description

technical field [0001] The invention relates to the field of mine safety prevention and control, in particular to a coal and gas outburst real-time early warning device and method based on multi-source information fusion. Background technique [0002] Coal and gas outburst disasters are one of the forms of coal mine gas disasters, which not only seriously damage the underground tunnels and facilities of coal mines, but also cause heavy casualties. my country's "Regulations on the Prevention and Control of Coal and Gas Outbursts (2009)" clearly require that outburst mines be strictly controlled. Good regional and local "two four-in-one" work, and the primary task of the "two four-in-one" is the outstanding risk prediction of the area and working face. Although the coal mine has established a complete outburst prevention management system and monitoring and monitoring system, there are also early warnings such as "a real-time monitoring and early warning system for coal and gas...

AI Technical Summary

Problems solved by technology

Although the coal mine has established a complete outburst prevention management system and monitoring and monitoring system, there are also early warnings such as "a real-time monitoring and early warning system for coal and gas outbursts", "a real-time tracking and early warning equipment for coal and gas outburst dangers in mines", etc. Devices are being continuously promoted, but coal and gas outburst disasters have not been effectively curbed. In practical applications, some early warning devices are often unable to truly reflect the degree of outburst risk at each mining operation point in real time due to the small amount of predictive index information. It is impossible to make accurate predictions and early warnings
