Large amounts of sample data are obtained from diamond drilling of in situ rock formations. Logged observations are normally recorded on pre-printed-forms for later analysis. Manual systems are being replaced by computer techniques for more comprehensive collection, storage and processing of data. The system described is built around a computer terminal with a cp/m operative system, and an optical encoder. A keyboard is used to communicate with the computer and a printer is connected for listing recorded information. The rockdisc code is written in OBASIC and stored on floppy-disc. Data can be converted for further processing on a minicomputer, the program plot-rockdisc is written in pascal and can be used to obtain a graphical presentation of borehole data. The graphical presentation obtained from the plot-rockdisc routine gives a top co-ordinate axis divided into 2 and 10 metre intervals. Geomechanical parameters in the first two rows are plotted in groups of three. Results of chemical analysis, texture and structure codes, rock types, core losses and crushed zones are also displayed.
