The Water-Disaster Characteristic Of Shandong Coal Mines And The Study On Its Aprroach To Water Prevention And Cure Technology

The hydrogeological condition of Shandong Province is comparely complex, andFeicheng, Xinwen, Zibo are all the famous water-rich mining areas in China. Thepaper studies the water-disaster type, water-disaster characteristic and coalmine water-disaster mechanism and discusses the approach to water- disasterprevention and cure in Shandong province. At the basis of the background analysisof regional geological and hydrogeological characteristic of Shandong coal mines,The paper summarizes the mining-coMbed and water-filled property;the paperclassifies the type of the water-disaster and its characteristic through thestatistics of the water-inrush material of Shandong coal mines; At the basis ofthe up "three zones" and down "three zones" theory, coalbed top layer andfloor water-inrush mechanism are studied;The water-disaster approach toprevention and cure of Shandong coal mine is presented from the aspect ofdifferent water-disaster type, regional, major, human-control, environmentprevention and cure.
