摘    要:基于同时满足力学参数相似和稳定电场参数相似的物理模型, 应用电阻率测深法详细研究了煤层上覆岩层在采动过程中的破坏过程与视电阻率的动态变化特征, 并通过反演计算得到了覆岩裂隙带、冒落带产生的视电阻率变化的倍数关系. 现场实测结果进一步证明了这一关系的正确性.

关 键 词:覆岩破坏  视电阻率  相似材料  物理模型

Abstract:Based on the physical modelling to satisfy simultaneously the similar conditions on mechanical propertics and constant electric filed properties, the dynamic feature between the failure process of overlying strata occured for mining process with the apparent resistivity was studied in detail by using the resistivity method. The times relationship of the apparent resistivity changing caused by the fractured zone and the caving zone was obtained by the computer inversion. The results in situ exploration prove still more its correctness.
Keywords:failure of overlying strata  apparent resistivity  similar material physical modelling
