Abstract: This study is interested in executing an optimal wavelet transform (WT) to interpret the continuous leak acoustic emission signal precisely. Thus, this paper proposes detailed guidelines on how to select an optimal mother ...

Abstract: Failure characteristics of rocks under different loading and unloading conditions have been an important subject of laboratory tests. This study aims to investigate the influence of the height to diameter (H/D) ratio on ...

Abstract: Underhand cut-and-fill stoping is an efficient, sustainable mining method that is particularly applicable to complicated mining conditions in which both the peripheral rocks and the orebody are extremely unstable. Considering ...

Abstract: Cubic specimens of three rocks—granite, marble, and sandstone, representing very strong rock, moderately strong rock, and weak rock, respectively—were tested under polyaxial stress. The objective was to determine the optimal ...

Abstract: Crystalline scorodite (FeAsO4·2H2O) is a common arsenic-(As-)containing solid waste produced from nonferrous metallurgical processes. Its stability is the key factor to determine environmental risks. Scorodite is stable ...
