Mine Design Relating to Dimensions and ... -

Mine Design Relating to Dimensions and Shape The aim of this aspect of strata control is to make the strata self supporting as far as possible, or if not, to minimize the extra support work required. With regard to opening size, this involves designing minimum practical widths for whatever operations are carried out and could involve modifying the design of equipment to fit into smaller openings.

Development Overview Introduction underground

Development in most mines is carried out by a number of separate development "units" each consisting of a full set of equipment (coal cutting machine, face transport equipment for coal and materials, roof support equipment and ventilation equipment) usually manned by more or less fixed crews on each shift. It is common for several such units to be operating more or less independently at several locations to
