摘要
针对断层等复杂地质条件数值模拟软件选取及命令程序语言存在的问题,采用通用离散元程序UDEC4.0并嵌入CRACK断层命令程序语言,模拟了1801首采工作面冒落带和裂隙带及覆岩随采动的变化规律,结合经验公式和仰孔注水测漏现场实测法掌握冒落带和裂隙带的高度,得出存在断层区域冒落带与裂隙带的高度大于非断层区域。
In view of existing problems to numerical simulation software selection and command language in fault of complex geological conditions,using the universal distinct element code UDEC4. 0 and the CRACK command language in the light of considering the existence's fault,the UDEC4. 0 simulated the two zone's height and the change laws of overlying strata,combining the empirical formula and upward hole injection water leak method to master the heights of caving zone and fractured zone,the result show that the existence of fault zone height greater than the zone fault zone to the two zone's height of caving and fractured zone.
