摘要:
受扰动的岩体力学参数是大型岩土工程设计和稳定性分析的基础与关键.本文采用地质力学分类法（RMR）、经验强度准则（GSI）、现场承压板试验与室内结构面强度试验等方法，综合确定金山店铁矿崩落法开采上覆岩层力学参数.并依据西Ⅰ采区工程地质、开采技术条件和岩体力学参数建立3DFLAC计算模型，验证岩层力学参数的可靠性.当开采到-141.5 m水平时，地表测点变形观测值与计算值在变化规律上一致，误差在允许范围内.因此，采用上述方法确定的岩体力学参数可以用于金山店铁矿东区地下开采的地表变形规律研究.
Abstract:
 Mechanics parameters of the excavationdisturbed strata are the basis and key factor in largescale rock and soil project design and its stability analysis. Using geological mechanics sorting method(RMR), experience strength criterion(GSI), onspot supporting plate test and indoor structural face strength test method, etc, this paper determines the mechanics parameters of the covering strata in mining with sublevel caving method. A 3DFLAC computing modality is also established according to the engineering geological and mining technological situation as well as strata mechanics parameters of the west I mining zone in order to verify the reliability of the strata mechanics parameters. The surface deformation pattern acquired from calculation is in accord with the pattern acquired from the surveying result on the surface observation spots as mining activities proceed to the -141.5 m level, and the error is in the allowable scale. Therefore, the strata mechanics parameters determined with the abovementioned method can be applied in the study of the surface deformation pattern of mining in the east zone of Jinshandian Iron Ore Mine.
