Rockbursts have been a hazard for mining operations since underground mining first came into practice; the consequences they present to mining personnel and machinery can be fatal and costly. Underground mining in Northern Canada has presented the opportunity to study the bursting properties of kimberlite. Very little research has been
surface mine. Determining the optimum underground mining method requires careful analysis of geologic, economic, and environmental data. By using a less rigorous approach, roomandpillarmining and blasthole open stoping were chosen as the mining methods most suitable to the development and mining of the mineral resources of the Duluth Complex.
Appendix D: Description of Mining Methods Shrinkage Stoping Shrinkage stoping is applicable to ore zones that are dipping at least 55 degrees and that range in width from roughly to meters. The enclosing waste rock must be competent and not subject to failure so that when the ore is drawn from the stope, dilution is kept to a minimum.
APPENDIX C.COST MODEL EXAMPLE . Once the mining type and the equipment to be used were finalized, the costs and depreciations associated with the equipment were developed. This procedure was done for each mining thickness category using that mining method in order to develop a total cost (, rail car) for the coal for each haulage zone.
