Hydrological Consideration Of Groundwater For Planning Of Mine Sealing At Japanese Mine

The most important consideration in planning the plugging and sealing of a mine for mine water control is to predict the water flow from the mine. For this purpose, a method of numerical analysis on the water behavior in the ground at the concerned mine area was developed and the mine water flows were simulated. A hydrological survey at the surface of the mine determined the recharge rate of ground- water and the apparent permeability of ground.
