Production geologists use information they obtain from sampling, testing, mapping and observation to determine the most efficient and effective mining techniques, as well as to identify the grade (amount of mineral) in the ore. In gold and silver mining, grade is reported as grams per ton. Copper grade is reported as a percentage.

Although production operations tend to be separate and cyclic in nature, the trend in modern mining and tunneling is to eliminate or combine functions and to increase continuity of extraction. For example, in coal and other soft rock mines, continuous miners break and load the mineral to eliminate drilling and blasting; boring machines perform ...

Dec 13, 2018 · It is the most common drilling technique used for mining exploration, particularly in South America and Australia. RC drilling is a form of percussion drilling, by which the rock is made to fail through the use of a piston that delivers rapid impacts to the drill stem, transferring energy to the drill bit.

The process begins by drilling a hole deep into the earth. To do this, a long bit attached to a "drilling string" is used. The bit varies in diameter from five to 50 inches. After each section is drilled, a steel pipe slightly smaller than the hole diameter is dropped in and often cement is used to fill the gap. Advertisement.
