Different characteristic of movement and deformation of overlying strata and surface include periodic caving of bed separation interspaced along with work face mining. Conglomerate rock layer movement is the main power fountain of rock burst on the basis of locale observation. And rock burst moves periodically adapted to movement of deep conglomerate rock layer which had similar characteristic with main roof. Practice indicates this method that forecasting and prediction using correlation information of movement of strata and surface is feasible and has reference meaning for similar stope.展开更多

It is accomplished by providing the software of controlling, interface and internal dose estimation programs to the original iron cabin shielding whole-body counter. The preliminary application shows that its data processing is rapid and correct, and can meet the requirement of rapid internal radioactive contamination monitoring and diagnosing in case of lots of internal contamination subjects happened innuclear accident.展开更多
