Abstract:

The characteristic of Salawusu Fm in Hang Laiwan area are introduced in detail and the water-conducting height is also given by empirical formulations in this paper. Furthermore, the flow characteristics and water level changes of Salawusu Fm aquifer are predicted by numerical simulations. Finally, a conclusion is reached that the water-conducting may be high enough to reach the Salawusu Fm aquifer, what provides a theoretical basis for prevention and control of the mine water.

Key words: Salawusu Fm, Water-conducting zone, Hang Laiwan area
