Analysis on Influencing Factors of Mining Subsidence under Thick Unconsolidated Layers

摘要

In this paper, FLAC 3D finite difference numerical model is established, the impact of influencing factors of mining subsidence under thick unconsolidated layers is studied, and obtain main influence factors, using orthogonal experiment method analyze the main controlling factors of mining subsidence under unconsolidated layers mining, set up the ordering of nine main factors. It lays a solid foundation of determining the input parameters for rock movement parameters prediction system.
