Abstract:
In order to solve the problems that the evaluation factors are not considered comprehensively and the evaluation conclusion cannot be quantified in the process of carrying out the gas drainage standard evaluation in coal mine enterprises, the AHP method is used to establish the evaluation index system of the basic conditions of gas drainage.First of all, the index system of gas drainage basic conditions is determined to meet the requirements of national regulations and specifications when the gas drainage standard is evaluated; secondly, the discriminant matrix is constructed and the weight of each evaluation index is calculated by the discriminant matrix; thirdly, according to each factor, expert scoring is carried out, and the evaluation model of gas drainage basic conditions is established by combining quantitative analysis and qualitative analysis; finally, the evaluation results are classified.Based on the quantitative analysis and qualitative analysis, this paper evaluates the basic conditions of gas drainage.The results show that the basic conditions of gas drainage in the mine are good, and the drainage test, drainage process design and drainage management are the weak links of the mine.The reason is that the reserve of talents is insufficient.The main reason is the lack of professional and technical personnel with design and research ability, which is in line with the actual situation of the mine.
