Abstract
This paper presents research, conducted by the Bureau of Mines on procedural techniques for computer assisted 3-D analysis of subsidence and its potential effects on surface hydrology. The prediction of coal mine subsidence through the use of a "Type A" computer model developed by Bureau researchers has enabled production of elevation data which can be incorporated into digital terrain models (DTM'S) and animated with CAD and 3-D modeling software. Bureau researchers served as unbiased authorities in negotiations between coal companies and landowners and used these tools to encourage multiple land use. Three case studies were done to enhance the ASPP subsidence prediction model's functiona1ity and a fourth was done to verify the accuracy of the ASPP model for the Rend Lake area of southern Illinois. These case studies involved DTM creation over about 40 proposed longwall panels for a preliminary assessment of surface hydrologic impact. Our results were considered in the permitting process for each mine.
