Abstract

On the basis of study for three-dimensional flow numerical model , The author analyzed influencing factor of variation in water level at Donglutian coal industrial ground by the parameter sensitivity analysis method. The results showed that there are several factors influence the change of ground-water level by filling, there were infiltrate performance of highly weathered sandstone, filling areas of precipitation infiltration recharge ability and blind drainage ability. In response to these main factors, author studied the permeability coefficient of all kinds of soil and rock layers, provided strong basis for improvement of surface drainage system and control quality of blind ditch. All of these approaches were to control the rise of ground water lever.
