Embodiment Construction

[0016] In order to make the above objects, features and advantages of the present invention more obvious and comprehensible, the present invention will be further described in detail below in combination with relevant theories and specific implementation methods used.

[0017] 1 The establishment of the index system of coal mine safety evaluation system

[0018] The present invention cites the safety evaluation of the coal mine production system as an example, and the research object is the entire coal mine production system. The target layer is coal mine safety evaluation; the first layer of decision-making indicators consists of six indicators: geological conditions, technical equipment, personnel quality, safety education, environmental safety, and management level; the second layer of decision-making indicators includes 26 items, and the index system is as follows: figure 1 .

[0019] 2 Factor set and comment set

[0020] The top layer is the target layer A, and the...

Abstract

The invention discloses a method for coal mine safety evaluation. The method for the coal mine safety evaluation is characterized in that the coal mine safety evaluation is achieved by means of the analytic hierarchy process, the genetic algorithm is used for realizing consistency of judging matrixes and determination of a sorting weight, and the coal mine safety evaluation is achieved by combination of the genetic algorithm and the fuzzy comprehensive evaluation method. The method mainly comprises establishment of a coal mine safety evaluation system indicator system, determination of a factor set, a comment set and the degree of membership, establishment of grading results and the judging matrixes, acquisition of the weight and a coincidence indicator function computed result, and acquisition of a safety evaluation conclusion. The method for the coal mine safety evaluation is capable of acquiring the weight of an element and realizing consistency of the judging matrixes by theanalytical hierarchy process, and can be widely used for the coal mine safety evaluation based on the analytical hierarchy process.

Description

technical field [0001] The present invention relates to coal mine safety assessment research, especially involving Coal mine safety is evaluated based on the improved analytic hierarchy process using genetic algorithm. Background technique [0002] Since the reform and opening up, the demand for coal mine energy in the country has increased year by year. The price rise of coal mines has led to many coal mines increasing their mining efforts. High-intensity production and mining have also led to frequent disasters and accidents in coal mines. Coal mining is a high-risk industry. Underground operations include many unsafe factors: gas, coal dust, roof, fire, water; temperature, humidity, wind speed, etc. in the mine, which threaten the life and health of personnel at any time. The causes of accidents are different, but the factors causing accidents are interrelated, so it is particularly important to evaluate the safety of coal mines. [0003] The difficulty of coal...
