STRAIN DISTRIBUTION AROUND UNDERGROUND OPENINGS. STATISTICAL METHODS TO COMPILE AND CORRELATE ROCK PROPERTIES - COMPUTER TECHNIQUES.

Abstract

A data tape is necessary for the storage of a systematized collection of physico-mechanical properties of rocks. Specific programs permit the obtaining of descriptive information on the data - ranges, means, and counts. Statistical routines yield histograms, scattergrams, and least squares equations. One objective is to provide information that can form the basis for some degree of uniformity in such research. Experience with the programs yielded certain principles and changes that would improve efficiency. It is recommended that one choose an efficient means of data storage, maintain a back-up data source and precise records, run all descriptive programs first, process as many cases per run as possible, determine common scales where necessary for later interpretation, and label output meaningfully.
