8.1 Surface Mining Methods. Surface mining deposits can be primarily divided as follows: Relatively horizontally stratified deposits with thick or thin overburden. Stratified and vein deposits dipping at angles; greater than the angle of repose of the spoil so that overburden cannot be deposited within the pit.

The economic analysis of the use of explosives is an important part of blasting operations in mining and construction. Explosives are energy, and the efficient use of this energy is a major factor in keeping rock blasting costs under control. High-energy explosives enhance fragmentation, which ultimately produces a positive effect on production ...

A drilling rig is a type of construction equipment used to make holes in the earth's surface. They can vary considerably in size: they can be massive structures or light enough to be moved manually by a single person. Drilling rigs can take samples from mineral deposits as well as test the physical properties of rocks, soil and groundwater.
