School of Resources and Safety Engineering... City University, Yiyang 413049, China)Abstract:Acoustic emission tests were performed using a split hopkinson pressure bar system (SHPB) on 50-mm-diameter bars of granite, limestone, sandstone and skarn......
A decomposition model to analyze effect of SO2 emission density of ChinaZHANG Ping-dan(张平淡)1, DU Wen-cui(杜雯翠)2, JIAO Sheng(焦胜)3, HE Li(何理)4(1. School of Business, Beijing Normal University, Beijing... pollutant emissions (taking industrial SO2 emission as an example) in China. From the results, it is found that 38.93% and 61.07% are contributed to environment-friendly and resource-saving effects......
Rock burst proneness prediction by acoustic emission test during rock deformationZHANG Zhi-zhen(张志镇), GAO Feng(高峰), SHANG Xiao-ji(尚晓吉) (1. State Key Laboratory for Geomechanics and Deep Underground... proneness was connected with the acoustic emission (AE) parameter in this work, which contributes to predicting the rock burst risk using AE technique. Primarily, a rock burst proneness index is proposed......
