• Description:
  Five important mine design problems are addressed by a user-friendly finite element package. Analyses of: (i) main entries, (ii) barrier pillars defending "mains", (iii) bleeder entries, and (iv) interpanel barrier pillars, all in longwall mining, and also (v) safety of rooms and pillars in room and pillar mining are readily accomplished. Distributions of stresses, displacements and local safety factors are obtained in three simple steps: (1) preparation of a strata properties file, (2) automatic, interactive mesh generation and (3) execution of a finite element program. The last is a simple "double-click"; the second is easy, while the first step is the most difficult because the elastic moduli and strengths of strata above and below the mining horizon must be known. A website http://ut3pc.net/ makes the UT3PC software and a User Manual available at no cost. Examples from coal, trona and other mines illustrate applications and results in extension of previous work (Pariseau, et al 2017). [Description provided by NIOSH]
