Embodiment 1

[0150] Example 1: Taking the No. 1 mine of Pingdingshan Coal Co., Ltd. as an example, a comprehensive evaluation of the health index of the ventilation system of the mine was carried out.

[0151] (1) For single-indicator unascertained measurement calculation, when evaluating qualitative indicators, according to the original description of the qualitative indicators, if they meet the corresponding grades, the indicator evaluation value is 1-3-5-7-9, when When the original situation is between the two levels, the index evaluation value takes the middle value of 2-4-6-8; when the value of the quantitative index is taken, the index evaluation value takes the corresponding measured data and calculation results. According to the measured data and index grading standards, the health index of the mine ventilation system of Pingdingshan Co., Ltd. No. 1 Mine was analyzed, and the evaluation values ​​of each index were obtained, as shown in Table 1.

[0152] Table 1 Values ​​of each eva...

Abstract

The invention, which belongs to the health index evaluation method of the ventilation system, provides an integrated evaluation method of a health index of a mine ventilation system. The method comprises: (1), a health index evaluation index system of a mine ventilation system is constructed from four aspects by using thirty-five diagnosis indexes as a basis; (2), weights of all indexes in the health index evaluation index system of the mine ventilation system at all aspects are determined respectively by using an order relation analysis method; (3), unascertained functions of all indexes are constructed; (4), a integrated health index evaluation model of the mine ventilation system is established; and (5), parameter data of all indexes are inputted into the evaluation model for processing to obtain all index coefficients and an integrated health index of the mine ventilation system. According to the invention, an effective technique management tool is provide for operation effect evaluation of the mine ventilation system; and the healthy state of the mine ventilation system can be checked and an accident inducement and a potential hazard symptom can be identified rapidly and accurately. The evaluation method is comprehensive and the output result expression is visual.

Description

technical field [0001] The invention relates to a method for evaluating the health index of a ventilation system, in particular to a method for comprehensively evaluating the health index of a mine ventilation system. Background technique [0002] The health index is a comprehensive dimensionless index that has been involved in all walks of life in society, such as river health index, ocean health index, enterprise organization health index, computer health index, land resources health index and mining area ecosystem health index, etc. In the mine ventilation system, the health index is used for comprehensive evaluation to realize the real-time "physical examination" of the entire ventilation system, so as to take measures in advance according to the abnormality of the ventilation system diagnosed and the results of the health "physical examination", so as to avoid or reduce the risk of coal mine accidents occur. [0003] Timely and accurate "physical examination" of the mi...
