摘　　要：为弥补矿井突(涌)水蔓延过程试验研究空白,科学揭示矿井巷道系统中水流蔓延规律,提出了矿井巷道系统突(涌)水蔓延过程物理仿真试验方法,并深入探讨了突(涌)水蔓延范围演变规律、巷道水深分布规律、水速影响特征以及巷道局部水流流动效应.基于巷道类型、布置方式、几何和结构特征,设计了矿井巷道系统试验原型,并依据重力相似准则按1∶10的比尺建立了矿井巷道系统突(涌)水蔓延过程正态试验模型.根据突(涌)水位置分布及其流量曲线演变特征分析,建立了多组试验工况,采用重力式循环供排水系统实现了不同工况下突(涌)水蔓延过程.研究结果表明:巷道水流蔓延具有以突(涌)水点为中心按高程分布的分区分级演变特性;巷道水深时变关系与突(涌)水流量呈正相关,正相关性下蔓型水深比上涨型水深显著;巷道整体水速与突(涌)水流量曲线增长幅度有关,增幅越大蔓延水速越快,累积突(涌)水量越多.单流程水速与突(涌)水量、水深和巷道坡度呈正相关,与巷道断面宽度呈负相关,其中水速对水深和巷道坡度变化最敏感;巷道局部结构突变位置下蔓水流会发生偏转效应,沿程或沿断面呈现水深和流速双值分布特性.试验结果与实际井下涌水数据相吻合,在水害智能防控与应急救援工程实践中具有广泛的应用价值.WU Qiang;ZHANG Xiaoyan;ZHAO Yingwang;LI Huiping;XU hua;WANG Xiao;College of Geoscience and Surveying Engineering, China University of Mining and Technology-Beijing;National Engineering Research Center of Coal Mine Water Hazard Controlling,China University of Mining and Technology-Beijing;School of Earth Science and Engineering, Hebei University of Engineering;State Key Laboratory of Hydraulic Engineering Intelligent Construction and Operation, Tianjin University;Information Engineering College, Beijing Instituteof Petrochemical Technology;Considering that the experimental research on the process of water inrush propagation in the mine tunnel system is still blank, a physical model test method for the flood spreading process in the mine roadway is proposed to scientifically reveal the flow law of water inrush in the mine tunnel system.At the same time, The evolution law of water inrush spread range, the distribution law of water depth in the roadway, the influence characteristics of water velocity, and the local water flow effect of roadway are discussed in depth.The prototype of the test mine roadway network system was designed by summarizing the type, layout, and structural characteristics of the mine roadway. Then, a normal test model of the 1∶10 mine roadway flood spread process was established based on the gravity similarity criterion.By analyzing the distribution characteristics of the water inrush location and the evolution characteristics of the water inrush flow curve, multiple sets of test conditions are established.Afterward, the gravity circulating water supply and drainage system is used to realize the spread process of flood under different working conditions. The boundary flow, roadway water depth, and water surface morphology during the test were monitored and observed. The research results show that the spread of water inrush in roadways has a hierarchical evolution characteristic centered on the water inrush point and distributed according to elevation;The time-varying relationship of roadway w
