EPANET在煤矿井下消防、洒水设计中的应用

Application of EPANET to Design of the fire protecting, sprinkling system in underground coalmine

将EPANET模型应用于煤矿井下消防、洒水计算中,用EPANET模拟井下管网布置,依据采煤方法和井下装备等确定初始节点流量,依据初始节点水量确定初始管径,运行后可直观显示出井下管网各节点水压,确定减压装置,简化手工计算,最后达到优化设计的目的。

EPANET nlodel was used in the fire protecting, sprinkling system iu underground coahnine, and imitate to arrange pipe network by EPANET. For purpose of simplify calculation and optimized design, the tollowing method will he used： initial node volumes measured by mine equipment and coal mining method, and initial pipe size determined by initial node volumes, each node water pressure will be measured after whole technology operation, then pressure reducing device will he determined.
