Surface Deformation Prediction System (SDPS) Software

Description

SDPS is an integrated approach to the problem of calculating and predicting ground deformations above undermined areas. Based on empirical or site-specific regional parameters, the model quantifies a variety of ground deformation indices for both longwall and high extraction room-and-pillar mines, including subsidence profile, angle of draw, strain, slope, and curvature, to name a few. The application includes a graphing program as well as a pillar stability program that can help evaluate the stability of pillars in room-and-pillar mines.

Factsheet: SDPS Fact Sheet 2018

  • Users: Engineers and Geologists.
  • Training: An online course is available via the TIPS Virtual Campus.
  • Vendor Information: SDPS is provided via the TIPS program to OSMRE, State and Tribal partners who work in the SMCRA community.  If you would like to purchase the software for your commercial use, please visit the Carlson Software website http://www.carlsonsw.com/
