Coal transportation – a conveyor belt system is used to transport the coal from the mining section to surface silos, ready for distribution to the market. The mining method chosen is believed to have less adverse impacts on the environment and the society. Furthermore, underground mining will still give allowance to agricultural activities.

Introduction. Underground Mining Methods and Equipment is intended as both a course and a technical reference for an audience of engineers, operators, contractors, consultants, regulators, practising geoscientists and students in the mining sector.
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.

Underground Mining Methods presents the latest principles and techniques in use today. Reflecting the international and diverse nature of the industry, a series of mining case studies is presented covering the commodity range from iron ore to diamonds extracted by operations located in all corners of the world. Industry experts have contributed 77 chapters.
APPENDIX C Mining THE indexes of output, employment, and manhours in the mining segment and the five major groups of mining industries are built upon those published by Harold Barger and Sam Schurr.' Their methods have had to be modified at a number of points so as to achieve consistency with other industry measures contained in this volume.

and underground methods. The Jay kimberlite pipe is located under Lac du Sauvage approximately 30 km southeast from the main Ekati camp and processing complex. A separate study considering open pit mining options for Jay Pipe was completed (by others) in 2010. DDEC has requested that Stantec consider the alternative of underground mining and
Coal Mining. Coal is a black or brownishblack shiny rock and most of it is buried deep underground so we must "mine" or dig it out. Finding coal used to be done by people called prospectors. Today it is done by geologists. There are two types of mining methods: Surface Mining and Underground Mining.
UBC Mining Method Selection (see Appendix II Mining Method References) is a modified version of the Nicholas approach for selection of mining method based on orebody characteristice (refer Nicholas 1981). Selection involves summation and ranking of numerical values associated with orebody characteristics that reflect the suitability of a particular method.
as the potential for subsequent underground mining. Although underground mining is not currently being planned for the Project, it may be considered at a future date. Effluent composition used for the toxicity testing was based on predictions from conservative modelling whose uncertainty is highest for the underground mining.
study done by Orica (refer to Appendix A – KSMSABREX Study) show that a drill hole diameter of 311mm (12 ¼") should be used for the main production drilling. Smaller diesel drills (165mm – 6 ½" hole diameter) will be used to drill the highwall and buffer rows. Production Drilling Production drilling will be done with electric drills.
