声发射能量累积与煤岩损伤演化关系初探
Investigation into law of AE energy accumulation and damage evolution on coal and rock
摘要
Abstract
In order to find out the relationship beween the energy accumulation and stress-strain during the fuilure process of coal and rock.the unaxial compression and AE experiments of the coal and mudstone were conducted,and the curves between the strain and AE energy accumulation and strain-stress were obtained.Based on the law of damage mechanics and thermodynamics, the damage evolution of coal and rock was deduced through analyzing the experimental results, subsequently, the curves of damage and AE accumulation were obtained.By analyzing and fitting the curves of damage and AE energy accumulation, the relation between the AE energy accumulation and stress-sWain was obtained, and the relation was verified through the experimental data.关键词
