摘　　要：将荧光检漏剂和实验紫外灯应用到物理模拟系统中,开发出新型采动覆岩固液两相运移可视化模拟系统,解决了以往固液耦合实验中开采覆岩裂隙及地下水流场演变不可视或可视程度差的难题。同时,以单轴抗压强度和渗透系数作为相似材料的关键指标,试制出新型的固液耦合相似材料,并基于SPSS软件分析了材料组分对相应指标的影响显著度。将此相似材料实验模拟系统应用于新疆伊犁一矿首采区覆岩移动规律分析中,检验了相似材料的适用性及该模拟开发系统的可靠性。This paper describes a new type of visual system for solid-liquid two-phase migration of mining-induced overburden. Fluorescence detection agent and experimental ultraviolet lamp were introduced into the physical simulation system to solve the problems existing in the previous system that the mining-induced overburden fractures and evolution of groundwater flow field were difficult to be tracked. Meanwhile, with the uniaxial compressive strength and permeability as the key indexes to assess the properties of the similar material, new-type solid-liquid coupling modeling has been developed, and the effect saliency of the composition of key materials on the both indexes were analyzed through the Statistics Package for Social Sciences. This similar material experimental system was applied in the analysis the overburden movement in the first mining area of Ili No. I mine, which proved the applicability of similar material and the reliability of the simulation system.
