| 摘 要： | 采用平面物理模拟实验,运用数字化声发射( Acoustic Emission,AE)技术对构造应力复杂煤层顶板在开采扰动中的局部损伤、变形及破裂过程进行了实时监测分析,对微裂隙结构及其与之对应的声发射动态参数进行了深入研究定量揭示了工作面不同开采技术条件下构造复杂顶板覆岩介质局部化损伤-破裂-失稳规律,为类似地质环境下工作面开采过程中矿山压力预警与围岩动力灾害控制提供有益借鉴

| Abstract: | By plane physical simulation,digital Acoustic Emission technology(AE) is applied to monitor and analyse in situ partial damage disturbance and deformation process from tectonic stress in complex coal seam and used to study the dynamic parameters corresponding Acoustic Emission.Also it is quantitative to reveal localized mechanism of damage,rupture and instability in complex roof strata.The result provides valid rules for underground pressure warming and surrounding rock dynamics disaster control in similar ... |
