Research of Mining Sequence in Deep Mining at Jinshandian Iron Ore based on Three-dimensional

Abstract

Abstract: In order to solve the high ground stress problem of deep mining faced by Jinshandian iron mine of Wusteel Group，and based on the analysis of occurrence characteristics of deep deposit and physical-mechanical properties of ores，4 kinds of mining sequence schemes were put forward，and the three-dimensional Elastoplastic FEM software was adopted to make numerical simulation on these four schemes.The sublevel stress distribution and safety factor for each scheme were analyzed，and the results showed that the downward and eastward mining sequence is conducive to realize the safe and highly efficient mining for deep ore body.

Key words: Deep mining, Mining sequence, Stress distribution, Safety factor, FEM simulation
