摘要/Abstract

摘要： 为了解决深部开采造成的冲击地压、大变形和常规锚杆/索破断失效等问题，本文以某煤矿釆区为研究试验段，基于高地应力软岩大变形破坏机理，采用FLAC3D-PFC3D耦合建模方法首次开展NPR锚杆/索动力学数值模拟研究，建立PR和NPR锚杆/索两种支护方案的数值模型，对比分析动荷载下硐室围岩以及锚杆的受力、位移情况.结果表明:25MPa冲击荷载下，25根PR支护锚杆/索中21根已失效，围岩大面积失稳，耦合墙出现严重变形，硐室呈现内凸弧形变形破坏.而相同条件下，NPR锚杆/索均未失效，硐室围岩稳定性保持良好.

关键词: 冲击地压；NPR锚杆/索；围岩支护；FLAC3D；硐室稳定性

Abstract: In this paper， a coal mine is used as the research region to study the problems caused by deep mining， such as rock burst， large deformation and failure of conventional bolt/cable. Based on the large deformation failure mechanism of high in-situ stress soft rock， the FLAC3D-PFC3D coupling modeling method was used to carry out the dynamic numerical simulation study of NPR (negative Poisson’s ratio) bolt/cable for the first time. Numerical models of two support schemes of PR and NPR bolt/cable were established， and the stress and displacement of the surrounding rock of the chamber and the bolt/cable under dynamic loads were compared and analyzed. The results show that under the impact load of 25MPa， 21 of the 25 PR support bolts/cables failed， the surrounding rock was damaged in a large area， the coupling wall was severely deformed， and the chamber presented inner convex arc-shaped deformation and failure. Under the same conditions， none of the NPR bolts/cables failed， and the stability of the surrounding rock of the chamber remained good.

Key words: rock burst; NPR bolt/cable; surrounding rock support; FLAC3D; chamber stability
