Production rates At full production, the reserves will be mined at a rate of 1, 788, 554 tons per year for open cast mining, and 1, 211, 446 tons per year for Underground mining, allowing 12 months ramping period for underground.
open pit and two underground mines. The deposit extends approximately 1,200 m SW-NE (along strike), 700 m NW-SE, and 700 m vertically. It is understood that the deposit remains open at depth. Open pit mining methods were used to evaluate the mining potential of this deposit as part of an update to a PFS published in 2011.

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 (f.o.b., rail car) for the coal for each haulage zone.

Appendix C: Selected additional readings on mine subsidence; Appendix D: Glossary; Introduction. The dictionary defines subsidence as the action of sinking and settling. The earth's surface can subside because of underground mining. Subsidence or the sinking of the ground surface due to mining starts with the removal of coal from underground
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 1.2 to 4.5 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.

open cut methods. Coal has been mined on the site for approximately 170 years. Underground mining commenced in 1937 to the west and north-west of current open cut mining (Figure 2), and the last coal extracted from underground operations was in 1992. Bloomfield produces mainly thermal coal with some semi-soft coking coal, principally for the
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
