There are two types of mine drainage: self-flow drainage and lift-up drainage.
The flat-flow self-flowing drainage is economical and reliable, and the water drains the water to the ground. The section of the ditch is inverted trapezoid, the effective area depends on the flow of water, generally 0.05-0.15 m2, the longitudinal slope of the roadway requires 3â€°-5â€°, and the flow rate of water in the ditch is 0.4-0.6 m/s.
The lift-up drain is used to drain the pump water to the ground. It is divided into fixed and mobile. The pump house is a fixed type of drainage. When digging the shaft and the inclined shaft, the water pump is suspended on the special steel wire rope and moved along with the excavation.
