Publisher Summary This chapter focuses on planning mass mining operations. The selection of mass-mining methods is the situation facing planners of new and current underground operations and those involved with the change-over from open pit to underground mining. Before a mining method can be selected, the potential mining environment must be defined in suitable terms so that the engineering ...
