Nowadays, the solid backfilling mining technology has been valued as an important technical mean of green mining. However, due to the complicated geological conditions, effective and efficient methods to monitor the deformation of the solid backfilling baby, are lacking in solid backfilling mining. Among various methods proposed by different scholars, an electrical resistivity (ER) method is one of the non-destructive monitoring methods that can be successfully applied in intelligent health monitoring of civil engineering structures such as roads. It is undeniable that there are obvious structure and mechanics differences between the solid backfilling mining and the conventional civil engineering. Therefore, the physical and mechanical characteristics of the coal waste rock backfilling material were studied, and the uniaxial compressive test, along with ER monitoring of material, were conducted in this paper. The relationships between the deformation characterizations and the ER of the waste rock backfilling material under various pressures were also analyzed. The test results suggest that the changed trend of stress is consistent with the ER in the process of compression, followed by the ER value increased with the increase of particle size ratio in a later stage of loading. This study provides insightful validation in monitoring the deformation characteristics of the waste rock backfilling material by ER method.

如今，固体回填开采技术已被视为绿色开采的重要技术手段。然而，由于地质条件复杂，固体充填开采缺乏有效、高效的固体充填体变形监测方法。在不同学者提出的各种方法中，电阻率（ER）法是一种可以成功应用于道路等土木工程结构智能健康监测的无损监测方法。不可否认，固体回填采矿与常规土木工程在结构和力学上存在明显差异。为此，对煤矸石回填材料的物理力学特性进行了研究，并进行了单轴抗压试验，在本文中进行了材料的 ER 监测。分析了废石充填材料在不同压力下的变形特征与ER之间的关系。试验结果表明，应力的变化趋势与压缩过程中的ER值一致，随后在加载后期，ER值随着粒径比的增加而增加。本研究为通过 ER 方法监测废石回填材料的变形特性提供了深刻的验证。试验结果表明，应力的变化趋势与压缩过程中的ER值一致，随后在加载后期，ER值随着粒径比的增加而增加。本研究为通过 ER 方法监测废石回填材料的变形特性提供了深刻的验证。试验结果表明，应力的变化趋势与压缩过程中的ER值一致，随后在加载后期，ER值随着粒径比的增加而增加。本研究为通过 ER 方法监测废石回填材料的变形特性提供了深刻的验证。
