摘 要: 为研究矿井防尘供水管网的可靠性,以开滦集团林南矿仓为背景,根据重力相似准则,推导变态相似条件下流量、压强的相似数,首次在实验室建立矿井供水管网的物理模型。对整个管网运行状态进行监测,测量监测点的流量和压强,并分别将实验结果和EPANETH软件模拟结果和原管网监测点数据进行对比,结果表明:管网模型满足变态相似条件下的重力相似准则,为以后进行矿井供水管网研究提供了实验基础。
关 键 词: 矿山安全;矿井;供水管网;重力相似;变态相似;EPANETH

Abstract: In order to research the reliability of mine dustproof water supply network, this paper deduces the similarity number of flow rate and pressure under the condition of abnormal similarity, and establishes the physical model of mine water supply network according to the gravity similarity criterion for the first time in Linnan mine as the background. The running status of the whole network is monitored, the flow rate and pressure of the monitoring stations are measured, and then the experiment result and EPANETH simulation result are contrasted with the data of the original network. The results show that the physical model meets gravity similarity criterion under the condition of abnormal similarity, which provides the experimental basis for the follow-up research on mine water supply network.
Key words: mine safety; mine; water supply network; gravity similarity; abnormal similarity; EPANETH
