Description
The BPG could be used as a reference document by relevant South African surface coal mines to review and enhance their Standard Operating Procedures (SOPs) for the management of hot holes. Moreover, the BPG may also be used as a reference document by relevant international open cast coal mines. In both instances, efforts must be made to ensure that the different recommendations are applicable and relevant to specific site conditions. The BPG is for open cast coal mines, particularly those with hot holes and is intended to be used by mining personnel such as drilling crews, blasters, blasting assistants, blasting foremen, mine overseers and production managers.

Mapping abandoned, inaccessible bord and pillar workings comes down to two options: borehole deployed laser or sonar scanning, or sensors carried in by unmanned vehicles. Drone mounted laser scanning for air filled voids and sonar carried by small submersibles for flooded workings were judged the most promising, but intrinsic safety, deployment and the risk of losing equipment still favour borehole methods for occasional use.

R1500,00
Compares labour intensive mechanised drill and blast underground mining with capital intensive bord and pillar using continuous miners, and adds the option of substituting locally made goods for imported supplies. Input data came from two mines running both types of section under comparable geological conditions, covering worker numbers, skill profiles, cost structures and import dependence, then calibrated to industry totals to drive a socio-economic model.
