Gravity flow, which pertains to the study of the flow characteristics of caved ore and rock, is a fundamental issue in the investigation of draw in caving mines. This chapter presents a series of research findings, including the flow characteristics of caved ore and rock under both near-field and far-field conditions, the flow characteristics of caved ore and rock with uneven particle size distributions, the evolution characteristics of the movement zone influenced by a single coarse particle, the flow characteristics of caved ore and rock under the influence of multiple coarse particles, and the uniform flow and stress evolution laws of caved ore and rock across multiple drawpoints. These studies were conducted using both physical tests and numerical simulations.
