Problems solved by technology

The model is feasible and reasonable in predicting the risk of coal and gas outburst, but the calculation complexity is increased by the accumulation of connection entropy
[0005] Through the above analysis, the main problems in the current risk assessment of gas explosion disasters are: (1) The commonly used assessment method is still the linear assessment method; (2) The model calculation is complicated and the operability is relatively weak

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 It is a flow chart of a WMNT gas explosion disaster risk assessment method of the present invention, and the method comprises the following steps:

[0022] Step 1: From the four aspects of "man-machine-environment-management", determine the index system of gas explosion disaster risk, and divide the risk level of gas explosion disaster risk;

[0023] The determined gas explosion disaster risk index system is shown in Table 1.

[0024] According to the characteristics of the coal mine production system, expert experience and the grading standards stipulated in the "National General Emergency Plan for Public Emergencies", the risk level of gas explosion disasters is divided into 5 levels: V={v 1 - safe, v 2 - safer, v 3 - general security, v 4 - less secure, v 5 -unsafe}.

Abstract

The invention discloses a WMNT gas explosion disaster risk evaluation method and belongs to the technical field of coal mine safety. The WMNT gas explosion disaster risk evaluation method includes the following steps that 1, a gas explosion disaster risk index system is determined, the levels of gas explosion disaster risks are divided; 2, weight vectors of all the indexes in the index system are determined; 3, a cost-oriented membership function or a benefit-oriented membership function are determined, and an index membership matrix is obtained; 4, target membership vectors of the risk levels are calculated; 5, the risk levels of gas explosion disasters are judged. The WMNT gas explosion disaster risk evaluation method is simple in calculation and good in operability, evaluation results are reliable, and a nonlinear gas explosion disaster risk level evaluation model is provided.

Description

technical field [0001] The invention relates to a method for evaluating gas explosion disasters in coal mine safety production, in particular to a gas explosion disaster risk evaluation method, which belongs to the technical field of coal mine safety production. Background technique [0002] Coal mine production system is a typical nonlinear system, which has the characteristics of complexity, dynamics and fuzziness. Currently, coal mine safety has become one of the main issues restricting the development of the coal industry. The frequent occurrence of gas explosion disasters has seriously affected the life safety of coal mine workers and the sustainable development of the coal industry. Since there are a large number of high-gas mines in my country, and with the increase of mining depth and the degree of mechanization, the amount of gas gushing out gradually increases; and the risk factors of gas explosion have nonlinear dynamic characteristics, so the risk assessment of ...
