(1) The water source of mine water damage,
The water sources that cause mine water damage include atmospheric precipitation, surface water, and groundwater. The latter include water in the aquifer or karst forming subsidence column, and water in the old vacant area. Mine water damage can be divided into the following categories, as shown in Table lG420112.
In recent years, water damage caused by stagnant water in the old kiln or accumulated water in the old vacant area and water in the collapse column has been particularly noticeable for various reasons.
(2) Mine water inrush channel The water inrush channel can be divided into two categories:
1. Naturally formed channels such as voids and fault zones in the stratum (1) Fractures and fault zones of the strata: When the joint fissures in the stratum are connected to each other, a fissure water channel can be formed. According to the penetration of the fracture zone, the fracture zone can be divided into two types, namely the water-blocking zone and the water-permeable fault zone.
(2) Channel karst: karst space from a tiny hole until dissolved Los huge hole, can communicate with each other, become a channel of communication of various water sources, many of our metal and nonmetal mines, are deeply hurt. The large cave itself is the source of stagnant water, and some of the collapsed columns are easily missed by geological exploration of boreholes, forming an important hidden danger of water damage.
(3) Pore channel: mainly refers to the intergranular pore water transport pathway in the loose formation. Such channels can transport the aquifers in the aquifer and can also serve as a conduit for communicating surface water.
2. The channel of the gushing water channel induced by human factors such as mining activities is mainly caused by exploration or mining, including the roadway top, or the crack channel and drilling channel formed by the top and bottom plates due to construction damage. (such as the vertical well) to communicate the water-bearing rock formations, or to cause crack communication during the surface collapse process.
Water source and water inrush channel for mine water damage
   There are two conditions in the mine that cause water damage in the mine, that is, ample pressurized water source and a water flow channel into the mine. Pressurized water refers to the head pressure relative to the affected location. The water flow channel may be original or may be caused by construction or other reasons.
