Book excerpt: This chapter of the study describes cut-and-fill stoping as it is practiced in Manitoba and examines the potential for improvements, especially of the procedure used at Inco's Thompson Mine in those areas where vertical block mine stoping is not appropriate. Cost and productivity applicable to Manitoba cut-and-fill operations are developed and compared with experience elsewhere. Cut-and-fill operations are described at the Thompson Mine and the Trout Lake Mine, representing the application of the method to narrow and wide orebodies respectively.

Book excerpt: Optimization of blast designs can be a rigorous exercise which involve numerous calculations using parameters that change from workplace to workplace. In addition, the results of any particular blast will have large effects on the production rates, mining cost, and dilution of the blasted ore. This project was initiated to provide a rational blast design tool for underground mines and their blasting personnel. The primary objective was to develop a user-friendly software package giving a good first estimate of a suitable blast design and capable of meeting day-to-day production requirements. The result was the BOULDER (blast optimization using locally determined engineering results) blast design optimization software. This report describes the data collection, design methods, and calibration, as well as the features of the software.

Book excerpt: A user friendly geotechnical database retrieval was set up to aid in the evaluation of mine stability and design. This system provides storage for pertinent mine data and allows the use of software grid manipulation or contour overlays to determine structural trends to aid in predicting potential ground problems. Contour plots of the mining geometry, and selected geological plots are constructed to determine if any relationships exist between wall slough or poor ground conditions and different geological parameters.
