The Application of Analytic Hierarchy Process in Mine Gas Prevention System

AbstractIn the assessment of mine gas prevention and control system, how to determine the weight of every main influence factor is a significant problem. In order to construct the mine gas prevention and control system sufficiently and reasonably, it is necessary to study the assessment indexes of the mine gas prevention and control system with the method of analytic hierarchy process, and determine the weight of each index, in the meantime, base the assessment on the quantization result of indexes. The study result shows that the main factors in the mine gas prevention and control system are gas monitor, gas outburst, ventilation condition and gas drainage. The weight value of each factor is determined through the method of analytic hierarchy process. The analysis results calculated accord with the practical situation, thus providing the direction for the survey of the assessment of the mine gas prevention and control system
