摘要:
开采扰动区断层采动活化是诱发动力学灾害的典型难题之一。断层采动活化诱发岩体动态变形规律研究是揭示煤岩体结构、应力与力学行为对灾害控制作用的基础前提。通过对物理相似模型实验和声发射、应力与变形指标监测,揭示开采扰动区断层下盘、断层附近及断层上盘随工作面推进覆岩运移和矿压显现规律。实验研究表明:断层存在破坏了煤层顶板及上覆岩层的整体连续性,工作面矿压及上覆岩层垮落规律表现异常,断层极易活化,滑移现象明显; 断层活化诱发上覆岩层发生整体切落,对工作面前方煤体产生很高的集中应力载荷,易诱发动力灾害。这为采动岩体动态断裂失稳和突水等灾害预报与调控提供理论依据。
Abstract:
The fault mobilization could cause the dynamical hazard in the mining disturbed zone.It is the basic premise of revealing the coal-rock structure and stress behavior in the control of hazard that research on the fault mobilization causing rock-mass dynamic deformation.Based on the physical modelling experiment and acoustic emission(AE),and stress-deformation index testing,the results showed that overlying strata migration and pressure behavior with trending around the fault.The results indicate that the fault disrupted the roof and overlying strata,which singularly broken.The fault was easily mobilized and the slippage destabilization was obviously prominent.This behavior could generate hyper-concentration loading in the coal-mass ahead of the working face and caused the dynamical hazard,these will provide the theory for the rock-mass breaking destabilization and water burst hazard prediction.
