摘要
对某新建矿井主排水系统和某生产中煤矿-430 m水平扩排系统进行分析,从泵房硐室高度、排水系统复杂程度和排水管路敷设难度上进行对比,得出了大涌水量矿井的排水系统适合采用双泵共管运行方式的结论,同时给出了采用双泵共管运行方式时水泵工况点的计算方法。
Analyzed the main drainage system of a new mine and the -430 m horizontal expansion drainage system of a coal mine in production, compared the height of pump room, the complexity of drainage system and the difficulty of drainage pipeline laying, and came to the conclusion that the drainage system of large water inflow mine is suitable for the double-pump common pipe operation mode. At the same time, gave the method to calculate the pump operating points when the double-pump common pipe operation mode is adopted.
