of granite to meet the demand of both domestic as well as export markets.. MINING Production of blocks of considerable size and weight is a special feature of granite mining. The process and equipment used for granite mining differ considerably from those used for mining other minerals. The mining of granite involves two important stages
Instead, granite miners use high-capacity extractors, cranes, tamb rock machines and chemicals to remove the granite slabs. Teams dig around the slabs to break them free, work that is tedious and difficult.
Bench blasting is the most widely used method of production blasting in quarrying, strip mining and construction excavation. This involves drilling inclined, vertical or horizontal blastholes in single- or multiple-row patterns to depths ranging from a few meters to 30 m or more, depending on the desired bench height.
