Several kinds of in-situ tests on groundwater were carried out in order to know the characteristics of groundwater flow in old coal field. The following results were obtained. The coal mining caused a loosened zone in the ground, an increase of permeability, and change in groundwater flow. The coefficient of permeability of ground in loosened zone was about 10-2 ∼ 10-4 cm / s, and it was about 100 ∼ 1,000 times that of non-loosened zone. It was found that the faults in ground sometimes behave like a permeable zone or impermeable zone. Therefore, we have to properly estimate the properties of fault in ground.
