Strength Characteristics and Failure Mechanism of Cemented Super-Fine Unclassified Tailings Backfill
This experimental study investigates the strength characteristics of cemented super-fine unclassified tailings backfill (CSUTB) and its failure mechanism. Physical and chemical properties of tailings from the Zhongguan Iron Mine (ZGIM) were tested. A series of uniaxial compressive strength (UCS) tests was conducted to determine the relationships between UCS of CSUTB and three factors of cement-...
متن کاملImplementation of Paste Backfill Mining Technology in Chinese Coal Mines
Implementation of clean mining technology at coal mines is crucial to protect the environment and maintain balance among energy resources, consumption, and ecology. After reviewing present coal clean mining technology, we introduce the technology principles and technological process of paste backfill mining in coal mines and discuss the components and features of backfill materials, the constit...
متن کاملBlast Simulation in Underground Mines Using the Combined Finite-Discrete Element Method
The purpose of this paper is to investigate the application of a combined finite-discrete element program, such as ELFEN, for the simulation and prediction of backfill stope failure risks due to blast loading effects in underground mines. A real size of a backfilled stope blasted in the nearby rock of the paste fill is modelled. The dynamic fracture propagation and fragmentation in rock and the...
متن کاملMultiphysics Modeling and Simulation of Strength Development and Distribution in Cemented Tailings Backfill Structures
Cemented paste backfill structures are complex underground cementitious structures. After fresh cemented paste backfill (CPB; a mix of tailings, binder and water) is poured into underground stopes (mined-out voids), its strength which is a key mechanical design criterion of CPB structures, gradually develops with time. The development of CPB strength is governed by the coupled thermo-hydro-mech...
متن کاملStudy of the Rheological Behaviors of Solder Paste
Solder paste is a homogeneous, stable suspension of solder powder particles suspended in a flux binder, and is one of the most important process materials today in surface mount technology (SMT). By varying the solder particle size, distribution and shape, as well as the other constituent materials, the rheology and printing performance of solder pastes can be controlled. Paste flow behavior is...
