为了研究井下工作面水压受供水管网中水量变化的影响,找出工作面水压变化的大致范围,以便在水压降到正常供水临界点前采取措施,通过变态相似理论并结合试验场地情况,推导出防尘供水管网相似准则数,以此搭建相似试验模型,并通过试验数据验证了模型的相似性。然后在此模型上通过试验来进行管网水量水压相关性的研究,并通过函数拟合的方式来对试验结果进行拟合。结果表明,与选定工作面共用管段越多,水量变化时,对该工作面水压的影响越大。
In order to study the water pressure in downhole face affected by the change of water volume in the water supply pipe network, find out the approximate range of hydraulic pressure changes in the face to take measures before the water pressure drops to the critical point of normal water supply. Through the metamorphosis similarity theory and the test site And deduced the number of similar criteria for dust-proof water supply network, in order to build a similar test model, and verify the similarity of the model by experimental data. Then on this model, the relationship between water pressure and pressure in pipe network is studied through experiment, and the test results are fitted through the function fitting method. The results show that the more common pipe sections with the selected working face, the greater the influence on water pressure of the working face when the water quantity changes.
