Abstract EN
In order to reveal the occurrence mechanism of coal and gas outburst and optimize the measures to prevent the disaster, a coal mine in Henan Province was undertaken as the research background.
Based on the geological and mining conditions of the coal mine, the gas geological analysis method is applied to determine the outburst occurrence and to classify the risk levels.
A multifactor pattern recognition method is used to determine the risk probability of the dynamic disasters such as coal and gas outburst.
The relationship between geological structure, rock mass stress, and mine dynamic hazards is determined using geo-dynamic division method and FLAC3D numerical simulation.
The occurrence and manifestation characteristics of the dynamic hazards are determined.
COMSOL Multiphysics software is used to evaluate the original prevention measures and to optimize the measures.
The research results determine the main influencing factors and regional distribution law of coal and gas outburst, which is of great significance to the risk prediction and prevention of dynamic disasters such as coal and gas outburst.
