2020-4-18Process Stage 1exploration and development. Planning for the development of room and pillar mines operates in much the same way as other mining methods and begins with establishing ownership of the mine. Following this the geology of the mine must be analysed as this will determine factors like the lifespan of the mine the production requirements and the cost to develop and maintain

2015-7-28highly productive mining methods are unselective and result in an increase in unwanted dilution. Often the adoption of a more highly productive mining method is precluded by the inherent decrease in head grade delivered by the method through this increased dilution. However bulk mining methods can lower the cost of mining and hence
