Abstract: The rational setting of pillar size parameters is crucial for the safe and efficient development and utilization of
underground bauxite deposits. Taking the mining system of No.III bauxite deposit of the aluminium ore in Loufan of Shanxi as the
engineering context, by employing a research methodology that combines theoretical analysis and numerical simulation, the
rational design and analysis of pillar size parameters for bauxite deposits were conducted. The research findings indicate that when
using the room-and-pillar method to mine underground bauxite deposits, the rational setting of pillar size parameters enables the
simultaneous protection of the coal seam and efficient development of bauxite resources; moreover, as the pillar size parameters
and spacing parameters increase, both the pillar's bearing stress and roof displacement increase correspondingly. The results of the
study can be used for the design of bauxite pillar size, explore the relationship between pillar size and pillar stress distribution,
and can provide theoretical support for the efficient development and utilization of bauxite in Shanxi Province.
