Improving safety and optimum design of ground support requires good and reliable ground characterization. While many geophysical methods have been developed for ground characterizations, their accuracy is insufficient for customized ground support design of underground workings. The actual measurements on the samples of the roof and wall strata from the exploration boring are reliable but the related holes are far apart, thus unsuitable for design purposes. The best source of information could be the geological back mapping of the roof and walls, but this is disruptive to mining operations, and provided information is only from rock surface.Interpretation of the data obtained from roof bolt drilling can offer a good and reliable source of information that can be used for ground characterization and ground support design and evaluations. This paper offers a brief review of the mine roof characterization methods, followed by introduction and discussion of the roof characterization methods by instrumented roof bolters. A brief overview of the results of the preliminary study and initial testing on an instrumented drill and summary of the suggested improvements are also discussed.展开更多

文摘为研究初始循环损伤对全级配混凝土断裂损伤特性的影响,对承受不同初始循环损伤的全级配混凝土梁进行三点弯断裂试验研究,并结合声发射(acoustic emission,AE)技术对预损伤后断裂过程进行监测。结果表明:初始循环荷载增幅越大,混凝土梁在初始循环阶段累积的损伤越大,损伤后再加载的峰值荷载越小,脆性特征更明显;对比分析多个AE损伤指数发现,在加载中后期,全级配混凝土的断裂特性受初始循环损伤的影响逐渐变小,此时试件的受损主要受到内部大骨料分布的影响;对预损伤后加载过程中RA-AF值(RA value-average frequency value)分析可知,剪切裂纹占比随加载进程的推进递增,但拉伸裂纹占比始终占主导地位,且随着初始循环增幅越大,破坏时剪切裂纹占比越大。研究成果对预测分析混凝土大坝断裂破坏具有较好的实际应用价值。
