[Abstract] 
Key Conclusions:
fiogf49gjkf0d
In the new ARMPS-LAM output, the stability factors (SF) of the Active Mining Zone (AMZ) from both programs along with the SFs for the barrier pillars, and other loading and strength data are all presented for comparison. Results from the new ARMPS-LAM are presented and explained. Also, the difference in the calculated output values from the two component programs are presented and analyzed.
Key Findings:
fiogf49gjkf0d
The new distribution version of the ARMPS-LAM program takes the typical ARMPS geometric and empirical parameters input for defining the mining plan and loading condition, and then automatically conducts both a traditional ARMPS analysis and a complete LaModel analysis of the given mine plan. From the user perspective, only the traditional ARMPS input is required; however, for the LaModel part of the analysis, the program automatically develops parameters and grids, and then runs and analyzes a full LaModel analysis, all without further user input. The user can run ARMPS-LAM in ARMPS 2010 mode and receive just the ARMPS 2010 output including all the ARMPS 2010 warnings or just run a complete LaModel analysis. In the latter case, no warnings will be generated and only LaModel related output will be generated. In addition, the user can specify a comparison analysis where results will be calculated for both formulations and compared side by side or in a graphical form.
Objective of the Paper:
fiogf49gjkf0d
The objective of this paper is to detail the development and methodology of the newly implemented laminated overburden code in the ARMPS program known as ARMPS-LAM. Using the basic geometric input parameters for defining the mine plan and loading conditions in ARMPS, ARMPS-LAM allows users to develop, run and analyze a full LaModel analysis of the mining geometry to output the stability factor on the AMZ. Utilizing the new laminated overburden feature of ARMPS, users are able to more accurately classify the stability of a given mine design.
Problem Statement:
fiogf49gjkf0d
A couple of years ago, a laboratory version of the computer code, ARMPS-LAM, was introduced at the ground control conference. This program integrated the LaModel laminated overburden model into an ARMPS-type analysis program. This ARMPS-LAM analysis has now been fully integrated into the ARMPS program.
