MULTI-SCALE ANALYSIS ON THE CHARACTERISTICS OF COAL INTENSITY DISTRIBUTION

摘要：

In order to study the discipline of the coal damage,the intensity distribution model of coal microcell is established.The research comes up with the characteristics of coal intensity which is based on the result of uniaxial compression experiment.The research indicates that the disorder distribution of the coal microcell determines the damage thresholds randomness in the system.The coals brittle fracture strength mainly meets the normal distribution,which is abie to explain the status of the stress concentration and the stress fluctuation.
