充填矸石物理力学性能实验研究

Experimental study on physical and mechanical properties of filling gangue

以充填矸石为研究对象,针对其力学性能开展实验探究。首先通过物理化学构成分析、电镜扫描、碎胀性分析三方面对充填矸石基本力学性能进行研究,并在此基础上借助单轴压缩实验机对充填矸石的压实特性开展实验分析,以对其实际应用进行有效指导。

The mechanical properties of the coal gangue which was taken as research object were studied in this paper. Firstly, the basic mechanical properties of filling gangue were studied from aspects of physical and chemical composition analysis, electron microscope scanning and swelling analysis. Then, the experimental analysis was carried out on the compaction characteristics of filling gangue with the aid of uniaxial compression test machine, so as to effectively guide its practical application.
