Theory and method research of geological disaster prevention on high-intensity coal exloitation in the west areas

On account of the nation basic research program of china(973 Program),theory and method research of ge- ological disaster prevention on high-intensity coal exloitation in the west areas,the total research route and related re- search prograss of western high-intensity coal exloitation geological disaster on four aspects of geological conditions, formation of geological disaster,evalution method and prevention has been formed. The stratum structure of coal rich region and characteristic of sediment dynamics had been reseached by the study of hydrogeology and structual geology research of jurassic-cretaceous in western coal rich region;And base on the behavior study of mining dynamics,the mechanism of large roof shear and sand-inrush had been found. Also the mining theory and method of major geological disaster and evironment damage also had been studied out. This paper ,which combines the geological disaster preven- ting and ecological environment protection organically,solves the key problem that had constrained western coal exploi- tation from headstream,can provide theoretical basis for safe and efficent green mining of western coal resources in long term and large scale.
