In today’s regulatory climate, proper mine planning and design to reduce the impact of subsidence is critical. Agapito Associates, Inc. (AAI) has the expertise to plan and design mines in order to reduce the impacts of subsidence at subsurface and ground surface.

AAI employs engineers whose geotechnical experience lies in projects requiring expertise in geology and soil/rock mechanics which relates to subsidence forecasting.  AAI staff have completed numerous subsidence forecastings and evaluations of planned solution mining as well as planned and active operating mines to assess potential subsidence impacts on near-surface pipelines and cables, roadways and roadway structures, and other natural gas assets.  We have used 2- and 3-Dimensional Finite Difference codes (such as FLAC2D and FLAC3D) as well as Influence Function codes (BASIN – AAI’s proprietary subsidence prediction software and Surface Deformation Prediction System (SDPS) for Windows).  AAI has been comparing measured subsidence (when available) with predicted subsidence.  A typical example is the study conducted by AAI at the SUFCO Coal Mine, Utah.  AAI also has been installing instruments for subsidence monitoring.
