Abstract: Gas explosion and coal spontaneous combustion disasters exhibit a complex coexistence. This paper introduces the concept of intelligent sensor, working principle and characteristics. Analysis of the status quo of gas explosion and coal spontaneous safety accident, points out that gas explosion and coal spontaneous are main hazards. Summarizes the basic problems of the basic method of coal mine gas detection and the existing gas detection equipment, put forward the research method by combining the intelligent gas sensor technology and traditional gas detection technology. Based on the implementation of an analytic hierarchy process and related investigations, constructed a hierarchical analysis model that optimizes a comprehensive prevention, high-efficiency mining technology. The result showed CO volume fraction at the rear part of the chock of less than 10-5, a gas volume in the upper corner of less than 0.5 % and a gas volume from the air return flow of less than 0.2 %.


Keywords: Intelligent sensor, Gas explosion, Spontaneous combustion, Optimization, Analytic hierarchy process.
