Abstract
With the development of coal industry,coal mine accidents occurred frequently,many of which were caused by hidden disaster-causing factors.In order to reduce the probability of accidents,ensure the safety of miners'lives and improve the level of coal mine safety production,it was of great significance to carry out the survey of hidden disaster-causing factors in coal mines.In this paper,Mengjiayao Coal Mine in Shanxi Province was taken as the research object.Through field investigation and data collection,the hidden disaster-causing factors of coal mines were identified,which not only strengthened the geological work of coal mines,but also provided a basis for effectively preventing coal mine accidents.The results showed that faults,fissures,folds,goaf,abandoned old kilns and poorly sealed boreholes were hidden disaster-causing factors.These were not hidden disaster-causing factor in the mine including collapse column,ancient riverbed erosion zone,skylight and other unfavorable geological bodies,and rock burst.关键词
