Water collection and drainage structure of mining method tunnel and construction method of water collection and drainage structure

The invention provides a water collection and drainage structure of a mining method tunnel and a construction method of the water collection and drainage structure. The water collection and drainage structure comprises main line tunnels, a pump room and a transverse channel, the two ends of the transverse channel are connected to the lowest points of the two main line tunnels, and the pump room islocated in the middle of the transverse channel and formed by expanding excavation of the transverse channel; and a sewage collecting pool is arranged on the lower part of the pump room, a leakage water collecting pool is arranged on the lower part of the transverse channel and the lower part of an area, close to the transverse channel, of the main line tunnels, and the leakage water collecting pool, the main line tunnels and the transverse channel are jointly built. According to the water collection and drainage structure of the mining method tunnel, the transverse channel is formed betweenthe lowest points of the t
