Research On The Hidden Hazards Of Water Disaster In Hongliulin Coal Mine

In recent years,the coal mine safety production situation has continued to improve steadily,the total number of accidents and the death toll continue to decline,gradually approaching the moderately developed countries.But serious accidents have occurred from time to time especially water disaster,for example Wangjialing coal mine water seepage accident and Shandong Huayuan mining company water break accident.A comprehensive survey of hidden hazards of water disaster in coal mines can take preventive measures and reduces the occurrence of water accidents effectively.Combined with the mining situation and geological characteristics of Hongliulin coal mine,this paper research on the hidden hazards of water hazards in Hongliulin coal mine,including:the development of the water conduction fractured zone,the situation of the underground aquifer,and the status of the goaf.At the same time,it is verified by drilling and geophysical methods,a more reliable conclusion is obtained.The drilling proved that the empirical formula is not suit for the prediction of the height of the water conduction fractured zone in Hongliulin mine.This paper established an equation which can predict the height of the water conduction fractured zone of Hongliulin Coal Mine.This paper has verified the range of fire area and the water-abundance by TEM and verified the distribution range of the goaf by 3D seismic method.Preliminary hazard analysis was used to determine the hazard level of the hidden hazards of the Hongliulin coal mine,and the main hazards of water were verified by using fault tree analysis method.Aiming at the hidden hazards of water hazards which have been proved,this paper puts forward corresponding prevention measures,some of which have been put into application to provide guarantee for the safety production of Hongliulin coal mine.
