THE MUTLI-PARAMETERS MEASURING METHOD FORECASTING WATER INRUSH FROM WORKING-FACES

Making use of the changes of inferior parameters of floor rocks with coal mining, the possibility of water inrush is analyzed and forecasted, which include numerical simulation and in-situ measurement. The double are combined to give comprehensive evaluation of water inrush possiblity. The paper emphasizes the fundamentals, device and work method of the means.
