    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.
