Natural water channel

First, the fractures and fracture zones of the formation. In a deposit in a hard rock formation, the jointed fissures may form a fissure water passage when the joints are connected to each other. Based on exploration and mining data, we divide the fault zones into two categories, namely the water-blocking fault zone and the water-permeable fault zone.

Second, karst channels. The karst space is extremely uneven and can range from tiny dissolved pores to huge caves. They can communicate with each other, serve as a conduit for communicating various water sources, and can also form isolated water-filled pipes. Many of our metal and nonmetal mines, are deeply hurt. The key to knowing this channel is to know exactly the karst development law and the characteristics of karst water in the mining area.

Third, the pore channel. The pore channel mainly refers to pore water transport between loose layers. It can be encountered when mining mining beds and mining deep bedrock deposits overlying loose layers. The former is mostly uniform water, which can only cause water inrush in large grain areas and mines with abundant water sources; the latter mostly cause damage during the construction period. Such channels can transport the aquifers in the aquifer and can also serve as a conduit for communicating surface water.
