[0059] (Example 1)
[0060] This embodiment implements the process of real-time analysis of the risk of coal and gas outburst for a certain heading face of a coal mine in Lu'an Group, Shanxi. The method of this embodiment for real-time analysis of the risk of coal and gas outburst includes the following steps:
[0061] ① Construct a mine safety monitoring and control system. see figure 1 , The driving face B1 of this embodiment belongs to the working face of the driving roadway B of the series-ventilated coal roadway. According to section 6.4 of the "Coal Mine Safety Monitoring System and Inspection Instrument Use Management Specification", the coal roads and semi-coal in 6.4.1 According to the design requirements of the methane sensor in the driving face of the rock and gas gushing out of the rock roadway, the first methane sensor located in the mixed air flow is set at a position less than or equal to 5m from the driving face B1 of the driving roadway B of the coal roadway T 1 ,...
