Description:The Bureau of Mines, U.S. Department of the Interior, has developed a program for the hewlett-packard hp-41c(V) that determines the change of position of a drill hole between two survey stations, using the radius-of-curvature calculation method. Values required to perform a single calculation are the bearings, inclinations, and measured depth at each station. The program automatically stores the most recent values of bearing, inclination, and measured depth for use in the next survey and automatically updates a set of hole position coordinate values. The program also asks for magnetic declination and project angle values upon initialization so that bearings obtained from magnetic compass data can be automatically corrected for declination and so that a cross section of the hole can be plotted. The program is friendly to the user, prompting for all required data entry and echoing the entered data and all output data with labels. It is also designed to allow correction of data entry mistakes and erasure of surveys calculated from errant data. [Description provided by NIOSH]
