Abstract: Hydraulic fill is often used to fill large underground voids created during mining operations. It is produced and distributed as a slurry at a pulp density (P) of 65–75% (solids content). Consequently, a substantial amount ...

Abstract: Evaluating the stresses in backfilled stopes constitutes a critical step for insuring underground mine safety and for analyzing backfill response. In recent years, the writers have presented several methods for conducting ...

Abstract: bservational analysis indicates that the East Asian jet stream consists of two separate branches: the East Asian subtropical jet (EASJ) and the East Asian polar front jet (EAPJ). The impacts of different intensity ...

Abstract: Bottom temperature time series recorded beneath the Gulf Stream at 265 and 589 m depth off the Georgia coast are compared with simultaneous time series of main thermocline depth determined from inverted echo sounder and ...

Abstract: This paper discusses the tracking speed for different types of sun tracking algorithms, particularly the latitude-oriented spinning-elevation tracking mode in the solar energy application. It is ...

Abstract: This paper studies wave propagation in strings with rigid bodies using the method of transfer matrices. The transmission property of a single rigid body is investigated. It is found that when ...

Abstract: Backfilling is commonly applied to aid pillar recovery in open stope mines. The backfill must then remain self-standing in the primary stope when mining an adjacent secondary stope. The design of exposed fill is often based ...

Abstract: Based on the knowledge of cognitive psychology, a kind of drivers’ cognition frame which combines intuition, analysis and inference was proposed, and the drivers’ cognition behavior in the process of car-following was ...

Abstract: The inelastic
