Study On Risk Assessment And Prevention Countermeasures Of Yangzhuang Coal Mine Water Disasters

Village and township coal mines have brought into some important effects on coal industry,but they are severity coal mine disaster areas in our country.So it is an event of significance to enhance their safety monitor and management.Yangzhuang Colliery is an emphases coal mine with an annual coal production of two million tons,its hydrogeologic condition is very complex。With the increase of mine depth,flooding injury threaten to mine production safety more and more heavy,the preventing and controlling work is very austerity.Geohydrologic characteristics are analyzed on the base of fully knowing the control theory and technology of water-inrush,this dissertation constituted the water disaster accident model,analyzed and evaluated the fatalness of water-inrush and discussed the prevention countermeasures of Yangzhuang Coal Mine.This dissertation focuses on the points below:1.Based on the analysis of the geology and hydrologic geology background, this dissertation analyzed and summarized the mining coal beds,structure and the earth'a surface hydrocele of the Yangzhuang Coal Mine and local coal mines around.2.Based on the research of coal mine water-disaster accident model and analysis of water inrush,constructed an Yangzhuang Coal Mine water-inrush accident model,presented a disaster evaluation method of coal mine water disaster, constructed a coal mine safety checklist.3.Evaluated the water disaster of the six local coal mines around Yangzhuang Coal Mine by using the above model and methods,the results validated these medhods.4.According to the different water disaster types and levels of Yangzhuang Coal Mine,some water disaster prevention and control countermeasures were put forward.
