Establishing Mine Water Supply Network Physical Model Based on the Abnormal Similar Theory

Abstract:

It’s necessary to establish a perfect dust water supply system according to Coal mine safety regulations. In order to do researches on the reliability of mine dust water supply network, this paper deduces the similarity number of flow rate and pressure under the condition of abnormal similarity, and establish the physical model of mine water supply network according to the gravity similarity criterion at first in lin-nan mine as the background. Monitor the running status of the whole network, measure the flow rate and pressure of the monitoring stations, and then contrast the experiment result and EPANETH simulation result with the data of the original network. The results show that physical model meets gravity similarity under the condition of abnormal similarity, which provides the experimental basis for the follow-up research on mine water supply network.
