采用实验室实验与定性分析相结合的方法,对混凝土材料和原煤单轴全程压缩加载破坏的微震信号规律及频谱特征进行了对比分析,初步探讨其机理。
The micro-seismic frequency spectra of coal samples and concrete samples during the uniaxial compression with full loading to destruction are expremetally studied. Results of the spectra and characteristics microseismic(MS) signals of the two different materials are compared and qualitatively analysed.
