Study Notes
Diamond Drilling
- In diamond drilling, the method of recovering cores by pulling the core barrel to the surface using a thin steel cable passing through the drill rods is called wireline drilling.
Mineral Deposits
- In evaluating mineral deposits, a positive ore reserve is sometimes referred to as probable ore reserve.
- The best and most widely used exploration method in developing an established area of mineralization or anomaly is core drilling.
Coal Deposition
- In coal deposition, strata refer to beds or layers.
Exploration Methods
- The exploration method highly applicable in locating and determining the thickness of wet shears, clays, or gravels is called resistivity.
- Geochemical prospecting is used to trace metals usually contained in water or stream sediment samples.
Diamond Drilling Samples
- In diamond drilling, the very fine and slimey samples collected are called sludge samples.
Coal Quality
- The most important quality specification of coal is its heating value.
- The measure of coal is expressed in terms of BTU (British Thermal Units).
Cement Production
- Aside from limestone, silica is another raw material necessary in the production of cement.
Core Logging
- For accurate logging of diamond drill cores, the core must first be wetted with clean water.
Coal Bed
- A stratum of coal or coal bed is called a coal seam.
Ferrogenous Outcrop
- A gossan indicates a ferrogenous outcrop.
Exploration Methods
- Core drilling is the best and widely used method in establishing area, depth, and thickness of mineralization, and is also used to gather data for ore reserves estimation.
- Diamond drilling is the most effective, detailed, and widely used method of exploration applied in developing or delineating an ore-body for the purpose of defining ore reserves.
Reconnaissance Exploration
- Initial reconnaissance exploration is usually conducted on drainage systems and tributaries.
Core Barrel
- A cylindrical chamber for receiving and retaining rock samples as diamond drilling progresses is called a core barrel.
