Fully-Mechanized Top-Coal Caving Mining Recovery Rate Analog Simulation and Numerical Simulation Study

Article Preview

Abstract:

The top-coal caving mining recovery rate is one of the important indexes of evaluating mining technical measures. This paper, by using the similar model and numerical simulation on the experimental analysis, fully integrates the advantages of numerical simulation and similarity simulation to simulate the rock mass deformation and stress rules in the two-slot mining process , and provides a strong theoretical basis for finding the technology of improving recovery rate of the comprehensive mechanized caving mining.
