Surface Deformation Prediction System (SDPS)
Calculate ground deformations (subsidence, strain, horizontal displacements,
slope, etc) based on the mineplan, surface topo and geological characteristics.
SDPS is a niche program developed through the Virginia Polytechnic Institute and
State University (Virginia Tech) and Carlson Software is the world’s only
distributor.
SDPS version 6.x constitutes the latest update of SDPS software, developed
specifically for the Microsoft Windows® environment. In this respect, all
programs fully utilize the central management of computer resources (i.e.
memory, use of the clipboard, peripherals, etc.) provided by Microsoft Windows®.
SDPS 6.x seamlessly interfaces with Carlson Software® on an AutoCad® platform,
all versions of AutoCad® by Autodesk as well as Surfer® by Golder and Associates
Version 6.x of the Surface Deformation Prediction System (SDPS) is designed to
provide an integrated approach to the following problems:
- Calculation and prediction of ground
deformations above undermined areas. Based on empirical or site-specific
regional parameters, the operator can calculate a variety of ground
deformation indices according to the profile function method as well as the
influence function method. Results can be plotted using the graphing program
provided, or exported to other graphing programs.
- Calculation of pillar safety factors
for room-and-pillar operations using traditional pillar stability equations,
as well as calculation of pillar stability factors using the ALPS and ARMPS
programs developed by the U.S. Bureau of Mines (now NIOSH).
- In addition, the following programs
also developed by NIOSH are included for completeness:
- the Analysis of Horizontal Stress
in Mining program (AHSM)
- the Analysis of Roof Bolting
Systems program (ARBS)
- the Coal Mine Roof Rating program
(CMRR)
- the Analysis of Retreat Mining
Pillar Stability – Highwall Mining program (ARMPS-HWM)
- the Analysis of Multiple Seam
Stability program (AMSS)
All NIOSH programs are included in SDPS for completeness and do not require a
license to run.
