Study on Mine Methane Risk's Synthetical Assessment and Application

摘要

By means of the analysis method of human-machine-environment, with plentiful safety data obtained from the investigation of mine safety condition around the country, the paper makes an in-depth study on methane risk, and confirms the basal hazard factors of methane risk. According to the theory of FTA, the logical relation of human, machine, methane and management is illuminated and the frame of assessment model is set up. The thesis studies the quantitative functions of the indices of human, machine, methane and methane accident, and analyses the relativity between methane risk and methane accident. The method that can confirm model parameters with regressive analysis of samples is present. The parameters of model are determined, and the concrete assessment model is obtained. The computer program for risk assessment is developed. By practical application, the risk assessment system is proved to be applicable and maneuverable.
