Drilling in mining - SlideShare

Surface mining requires drilling for different purposes that include: 1. Production drilling i.e. for making holes for placement of explosives for blasting. The objective of drilling and blasting is to prepare well-fragmented loose rock amenable to excavation with better productivity from the excavation machinery.Drilling and Blasting | Technical Aspects of Mining,,In surface mining, benches form free faces and the holes are drilled in patterns relating to this plane. In U/G stoping, the same principle applies and it is relatively easy to retain a free face. Generally, holes are drilled parallel to each other.Working principle of drilling machine,Drilling is a cutting process that uses a drill bit to cut or enlarge a hole of circular,. The main principle consists in generating axial vibrations or oscillations in,be moved simultaneously in an axial direction to drill or machine a hole – and/or... More details » Get Price

Drilling Machine: Definition, Types, Parts, Working,

Working Principle of Drilling Machine: When the power is given to the motor, the spindle rotates, and thereby the stepped pulley attached to it also rotates. On the other end, one more stepped pulley is attached and that is inverted to increase or decrease the speed of the rotational motion.How Oil Drilling Works | HowStuffWorks,Oil drilling a complex process that involves the drilling and pumping of oil from underground wells.
