Abstract: Mine water prevention and control is very important for mine safety production. Mine water prevention and control is mainly divided into two aspects: roadway water control and surface water control. Surface water prevention and control is the first line of defense to prevent mine flood, and it is very important to protect industrial sites and underground from the threat of floods. Taking Buertai Coal Mine, the one with the world's largest design and production capacity, as an example, it introduces design and construction of rainwater collection system, flood control ditch, rainwater strong drainage pumping station and rainwater pressure drainage pipeline in surface water control project of the mine industrial site. By analyzing the underlying surface conditions and rainfall parameters, a perfect site rainwater collection and drainage pipe network is designed. In order to exclude the catchment of hillside in the southwest of the site, a flood control ditch was designed to drain the catchment of hillside into the Ulan Mulun River. A rainwater pumping station and a rainwater pressure drainage pipe are designed, because the highest flood level of the Ulanmulun River is higher than the lowest level of the site,. A pressure drainage pipe is designed to cross the railway in a sleeve form, which is conducive to energy saving and train safety.
