Problems solved by technology

In the current actual production, the commonly used ventilation system evaluation methods in mines are mainly manual judgment methods, which are mainly obtained through human subjective experience. For large-scale mine systems, this obviously cannot meet the requirements, and also wastes a lot of human resources.

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with specific embodiments, but not limited to specific examples.

[0013] The comprehensive evaluation method of mine ventilation system based on gray cluster analysis, the specific implementation steps are as follows:

[0014] 1. Collect the data value of the ventilation system in the mine.

[0015] 2. Use the gray scale evaluation method of the whitening weight function to evaluate it at the first level. The specific implementation method is:

[0016] Step 1: According to the number of categories s required to be divided according to the evaluation requirements, the value range of each evaluation index is also divided into s gray categories accordingly. For example, the value range of the j indicator [a 1 , a s+1 ] is divided into s intervals [a 1 , a 2 ],...,[a s , a s+1 ].

[0017] Step Two: Use

Abstract

The invention relates to an evaluation method for mine safety system, which is a combined evaluation method for mine ventilation system based on grey cluster analysis. The mine ventilation combined evaluation problem can be solved based on grey cluster analysis theory and by using the method of quantitative analysis. Comparing with the prior method, the method has the characteristic that the evaluation is objective, accurate and high sensitivity, which is in particular suit for the management of the large-scale mine ventilation system.

Description

1. Technical field: [0001] The invention relates to an evaluation method for a mine safety system, in particular to a comprehensive evaluation method for evaluating a mine ventilation system. 2. Background technology: [0002] The purpose of the mine ventilation system is to provide enough fresh air for each working place in the mine, so that the toxic and harmful gas and dust in it will not exceed the specified value. Mine ventilation is one of the most important technical means to ensure mine safety. Therefore, a comprehensive evaluation of mine ventilation system is an important basis for modern mines to formulate production plans and make technical plan decisions. In the current actual production, the commonly used ventilation system evaluation methods in mines are mainly manual judgment methods, which are mainly obtained through human subjective experience. For large-scale mine systems, this obviously cannot meet the requirements, and also wastes a lot of human resource...
