The causal mechanism of gas-coal cross-mining accidents

Abstract

The problem of overlapping mineral rights of coal and gas is common in the Ordos Basin of China.The interaction will occur when coal and gas are mined simultaneously, so it is necessary to solve the synergistic mining problem to eliminate the accident potential.Considering that there are many constraints in the simultaneous exploitation of gas and coal, this paper proposed an energy control failure model by energy abnormal release and STAMP.This model explains the applicability of information transfer cycle and the energy control failure model.Then, through the analysis of gas-coal mining process, this paper established the interaction between the energy unit, barrier unit, and disaster-bearing body, and analyzed the characteristics of energy transfer and safety barrier interaction.Finally, by analyzing 9 kinds of accidental release scenarios, this study proposed the identification behavior methods and control measures to prevent gas-coal cross-mining accidents.
