a deposit with groundwater as the main source of water

The aquifer that can cause water in the wells is called the water-filled layer of the deposit. When groundwater becomes the main source of water inrush, there are the following rules:

(1) The intensity of water inrush in mines is related to the porosity of the water-filled layer and the degree of water enrichment.

(2) The water inrush intensity of the mine is related to the thickness and distribution area of ​​the water-filled layer.

(3) The intensity of water inrush in mines and its changes are also related to the composition of water in the aquifer.
