GIS和FLAC~(3D)耦合下的采场上覆岩层破坏空间分布
|
摘要
在分析GIS空间数据模型和FLAC3D初始单元模型的基础上,通过GIS栅格数据模型与FLAC3D的六面体单元(Brick)模型的数据耦合,提出了两者耦合下的煤矿采场三维空间构模方法。利用该方法在数值模拟计算结果的基础上建立了GIS时空数据库,以"三带"的断裂带上限值定义了上覆岩层破坏高度函数。结合汝箕沟煤矿32211工作面的开采实际,计算了工作面上覆岩层破坏空间分布,给出了终采线附近上覆岩层破坏高度。
Based on the analysis of GIS spatial data model and the primitive cell model of FLAC3D,the methodology of 3D spatial modeling for coal mine workface by using GIS and FLAC3D was proposed and implemented by coupling the raster data model of GIS and the brick model of FLAC3D.Using this method in numerical simulation,a spatio-temporal GIS database was built,and the failure height function of overlying strata was defined by using fracture zone as a upper limit value in the "three zones".The method was used to calculate the spatial distribution of overlying strata failure in 32211 working face at Rujigou Coal Mine,and the failure height near the stop line was given.
