特大型矿井地面防治水工程中雨水收集排放系统设计

以布尔台煤矿为例，介绍了该矿工业场地地面防治水工程中雨水收集系统、防洪沟、雨水强排泵站和雨水压力排放管道的设计和建设情况。通过分析下垫面情况及降雨参数，设计了完善的场地雨水收集排放管网。为了排除场地西南侧山坡汇水，设计了防洪沟将山坡汇水排入乌兰木伦河。由于乌兰木伦河最高洪水位高于场地最低点场平标高，设计了雨水强排泵站和雨水压力排放管，压力排放管采用套涵形式从铁路下方穿越，利于节能和列车行车安全。

Design of rainwater collection and drainage system for surface water prevention and control works in Oversize mines

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.
