Telephone: 08-665 28 00 APPLICATION OF COMPUTER AIDED DESIGN (CADD) IN DATA DISPLAY AND INTEGRATION OF NUMERICAL AND FIELD RESULTS - STRIPA - PHASE III D. E. Press S. M. Halliday J.E. Gale Fracflow Consultants Inc. St. John's, Nfld., Canada December 1990 This report concerns a study which was conducted for the Stripa Project. The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the client. A list of other reports published in this series is attached at the end of the report. Information on previous reports are available through SKB. 11 Abstract Existing CAD/CADD systems have been reviewed and the micro-computer compatible solids modelling CADD software SilverScreen was selected for use in constructing a CADD model of the Stripa site. Maps of the Stripa mine drifts, shafts, raises and stopes were digitized and used to create three- dimensional images of the north-eastern part of the mine and the SCV site. In addition, the use of CADD sub-programs to display variation in fracture geometry and hydraulic heads have been demonstrated. The database developed in this study is available as either raw digitized files, processed data files, SilverScreen script files or in DXF or IGES formats; all of which are described in this report.
