受载煤岩力电耦合的损伤力学修正模型
Revised coal or rock under load damage mechanics model of coupled stress & electricity
摘要
Abstract
Based on the statistical distribution hypothesis of rock strength and damage mechanics, and by introducing a damage factor of δ, a statistical damage model on the coal or rock strength is established, and the meanings of the parameters α and δ are analyzed. On this basis, taking the ratio of the coal and rock material electromag netic radiation pulses cumulative number generated in a certain deformation stage and that of all damage as the damage parameter φ ( ε) which follows the Weibull distribution, The paper sets up the revised damage mechanics model of coupled stress & electricity of coal or rock under load, which not only embraces the primary model and but also can describe relationships among EMR, stress and strain. This model can provide theoretical foundation for predicting dynamical disasters of coal or rock in situ.关键词
