Description
Summary:The diamond core drilling operation is very essential in the preliminary stage of mineral extraction in the mining industry. The energy required to remove a unit volume of the rock mass (specific energy) is discussed in the present investigation. Estimation of the specific energy is the essential key parameter for tunneling, excavation, and other allied industries. It helps in reducing the time-consuming and cost of the project. For that, the laboratory experimental work was carried out on a laterite rock using CNC drilling machine BMV45T20. Using a multiple regression analysis reasonable mathematical equation was established among specific energy and dominant frequencies through diamond rock core drilling operations. The established prediction model could be utilized at the preliminary stage of the excavation projects for estimation of the specific energy in tunneling, excavation and petroleum industries.
