基于UDEC的岩层与地表移动动态模拟研究

Dynamical Simulation of Rock Strata and Surface Movement Based on UDEC

以UDEC为研究平台,讨论了数值计算时的开挖模拟和迭代运算问题。通过计算实验,提出并建立了以开采充分性和推进速度为变量的单元开采迭代次数的计算方法,分析了岩层性质及工作面推进速度等因素对岩层及地表移动变形的影响规律,为岩层及地表动态移动变形的模拟计算提供了参考。

Mining simulation and iteration calculation in numerical simulation was discussed based on UDEC software. A calculation method of zone mining iterations was put forward which took mining sufficiency and mining speed as variables. By this method,the influence rule of rock properties and mining speed on rock and surface movement and deformation were analyzed,which provided reference for simulation and calculation of rock and surface dynamic movement and deformation.
