Abstract
The ore drawing procedure of the synchronous filling shrinkage mining method is simulated using PFC software. Isolation layer thickness \(A\) , isolation layer interface friction factor \(B\) , ore particle friction factor \(C\) , particle radius \(D\) and wall friction factor \(E\) are chosen as the five influencing factors of the orthogonal test, along with the characteristics of the orthogonal test and force chain parameters. The findings demonstrate that the primary and secondary order of each factor impact on the orthogonal test index is \(D>C>A>E>B\) The best test configuration was \(A_{1}B_{2}C_{3}D_{3}E_{3}\) , with the relevant factors being thickness 0.003 m, isolation layer interface friction factor 0.5, particle friction factor 0.8, particle radius 0.008 m and wall friction factor 0.8.
