... ABSTRACT: A computer program WAVE has been developed in CSIR-MiningTek as part of its elastodynamic research in the Rock Mass Behaviour project. It allows efficient elastodynamic modelling of twoand threedimensional orthogonal geometries on a personal computer. Today, models with over...

... ABSTRACT ABSTRACT: The computer program introduced in this paper is based on design guidelines developed for selection of support systems used in mine roadways. The support types considered include rock bolts as well as rigid and yieldable steel arches. Using the computer program, the design...

.... The functions relating initial and steady state subsidence of a point over-lying an excavation were found to correlate to extraction through an influence function. A computer program was developed to predict subsidence using a zone area method of influence function. The results show reasonable correlation...

..., the application of hydrostatic and rock bolt forces and more. A program listing is given in the paper. The computer program is based on the one published by Hendron, et al. (1971) in their report titled "Analytical and Graphical Methods for the Analysis of Slopes in Rock Masses." 2 INTRODUCTION The stability...

... is predicted using a computer program and the results of fragment size measurements and laboratory leaching tests. BLASTING TESTS The Sierrita mine test was a nine-hole blast detonated with blasthole spacings of 15, 20, and 25 feet and powder factors of 1.13, 0.64, and 0.41 lb/ton, respectively...

..., Langefors and Kihlström /1/ have assembled a generalized basis for engineering calculations of many different rock blasting situations. Computer techniques together with a large experience in blasting techniques have made it possible to develop advanced computer program for bench and tunnel blasting...

... ABSTRACT The paper describes a computer program that can model the behavior of assemblages of rock blocks and visually display this behavior on the screen of a Cathode Ray Tube. There are no restrictions on block shapes and no limits to the magnitudes of displacements and rotations...

... water jets as the cutting tool. To obtain a better understanding of the relationships between these performance parameters, a computer program was written to serve as a model of the tunneling machine. Experimentally established data were used to select various combinations of parameters as input...
