ALPS (Analysis of Longwall Pillar Stability) is software for designing pillars for longwall mines.The ALPS method, which is embodied in the program, consists of three basic steps:Estimating the loading that will be applied to the pillars during all the phases ...

AMSS is a software program that helps to identify the location and likely severity of multiple seam interactions. Multiple seam interactions are a major ground control hazard in many US underground coal mines. The two most common types of interactions are:<ul><li>Undermining, ...

Analysis of Roof Bolt Systems (ARBS) is software to aid in the selection of roof bolts for primary support in underground coal mines.

ARMPS (Analysis of Retreat Mining Pillar Stability) is software for designing pillars for room-and-pillar retreat mining. ARMPS calculates stability factors based on estimates of the loads applied to, and the load-bearing capacities of, pillars during retreat ...

<p>ARMPS-HWM is a modification of Analysis of Retreat Mining Pillar Stability (ARMPS) software for designing web and barrier pillars for Highwall Mining (HWM).</p>

<p>Program AXILTR, AXIal Load-TRansfeR, consists of a main routine and two subroutines. The main routine feeds in the input data, calculates the effective overburden stress, and determines whether the load is axial down-directed, pullout, or if uplift/downdrag ...
