 this study examined the stability of a coal pillar roadway under the influence of intense dynamic pressure from mining activities. It was found that an unreasonably wide coal pillar can lead to severe deformation of the roadway as well as subsidence at the coal pillar side of the roof. To address this issue, a six-meter wide coal pillar was determined to be the most suitable width. Additionally, a combined support system consisting of anchor cables, grouting, and single props was developed and implemented to ensure the safety of the mining operations.
