大型矿井排水设备选型计算

Calculation and selection in drainage equipment for oversize coal mine

排水设备选型的优劣不仅直接影响矿井初期投资和运转费用,而且影响安全生产。根据现代化大型煤矿-红庆梁矿井正常涌水量及最大涌水量,给出了矿井排水设备选型与计算方法。通过计算水泵排水能力、管路阻力系数、工况点参数、排水管路壁厚、电耗,确定主排水设备和应急排水系统选型结果,为大型矿井的排水设备选型提供参考。

Selection of drainage equipment not only directly affect the merits of the initial mine investment and operating costs, but also affect the safety in production. The method of calculation and selection for main mine drainage equipment is given in this paper based on a new modern coal mine such as Hong Qing Liang mine that normal water gushing and the largest water inflow. the selection results of determine the main drainage equipment and emergency drainage system provide a reference for a large mine drainage equipment selection by calculating the drainage capacity, pipeline drag coefficient, pump operating conditions parameters, drain line wall thickness and power consumption.
