Arthur J. Hoskin The Business of Mining

Having considered the accepted definition of a mine, let us now extend our reasoning a little and inquire just what is meant by mining. At first thought, one would say that mining is, in a broad sense, the art or practice of excavating, at a profit, the ores of metals, the beds of coal, the gravels of placers and the deposits containing precious stones. Are we justified in letting this definition stand as it is? If we do not make any change, we must exclude all quarries, sand banks, clay pits, and the numerous sorts of works that are producing the non-metallic minerals of commerce.

Mining may be said to begin whenever there is produced an output upon which there is some profit. Exploitation may be in valuable ground. If so, we may say that mining is in progress during the exploitation. The driving of levels or drifts in an ore body—or of entries in a bed of coal—produces the valuable products of the mine, and we may, therefore, consider that mining is taking place.
The driving of a crosscut through barren rock to reach an ore body is dead work; but the driving of a drift or level in a vein is either exploitation or mining. Dead work produces no ore.

As stated above, the qualities that make a good manager are inherent; hence, to a certain extent, we may hold the deduction that good mining engineers, also, must possess innate qualities. Yet there may be pointed out this distinction between the make-up of a good man for manager and that of a good mining engineer: one, as said, cannot learn his business except through his own experience, while the other can receive vast benefit by study of a theoretical nature and by practice.
