Strata Behaviors of Fully-Mechanized Sublevel Caving Face Based on Similar Simulation Test

Advanced Materials Research, 2013
in view of research situations of the fully mechanized sublevel caving, the similar simulation test model for fully mechanized sublevel caving was presented. During the top-coal caving process, variation of top-coal subsidence and abutment pressure were measured.

Numerical Simulation of Distribution Regularities of Dust Concentration in Fully Mechanized Top-Coal Caving Face

2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010
According to characteristics of fully mechanized top-coal caving face and related survey date, a mathematical model of dust movement was derived from gas-solid two-phase flow theory. Numerical simulation of the dust concentration was made with CFD software FLUENT. The result matches well with the related survey date and shows that most of the dust move

Study on Abutment Pressure Distribution Law of Fully-Mechanized Sublevel Caving Face in Extra-Thickness

Advanced Materials Research, 2015
Based on field observation, analogy simulation and theoretical analysis, the abutment pressure distribution law of fully-mechanized sublevel caving face with extra-thickness was studied. The results showed that: Different instability type of the structure ‘Combined cantilever beam-articulated rock beam’ in fully-mechanized sublevel caving roof led to ...

Statistic constitutive equation of top-coal damage for fully mechanized coal face with sublevel caving

Journal of Coal Science and Engineering (China), 2008
Under the action of abutment pressure in front of fully mechanized coal face with sublevel caving (CFSC), top-coal over CFSC deformed. In the process of whole deformation of top-coal, it changed from continuum elastic mass to non-continuum plastic mass contained fissures, become a loose body.
