摘　　要：水下煤矿开采在进行相似材料实验研究时都应进行固液两相模拟,但由于对两相实验材料的研究一直未取得突破性进展而未成功。在成功研制固液耦合实验材料的基础上制作了固液两相相似材料模拟模型,通过水体下煤矿开采渗流实验模拟,得出了水在工程破坏岩体中的渗流以及岩体在渗流场作用下的破坏规律,取得了保水开采的合理参数。实验所得的参数为现场开采实践所证实,这为水体下煤矿安全开采设计、矿区水资源保护、绿色矿区的实现提供了可靠的依据。A fluid-solid coupling simulation must be made when people do an experimental research on similar materials in a mining area coved with water, but it has been not succeeded because people have not found the long-term suitable coupling materials. The similar materials simulation model is made on the basis of researching on the solid and fluid coupling experimental materials. Through the simulation of seepage experiment in mining area covered with water, the law of water fluid in destructing rock and the law of rock＇s destruction in fluid field are drawn, and the reasonable face＇s excavating distance is definited in mining coal. The experiment＇s reliability is proved by the field observation. This provides a reliable basis for the mining design, water resources protection and the realization of environmental protection and has the important guidance meaning.
