Mining is one of the oldest industries, but it is only during the last 50 years that operations have been carried to depths where problems of temperature and ground pressure require special study. Temperature problems can be solved by increasing the now of ventilating air and or conditioning the air by refrigeration. Controls of this nature are limited only by economic factors. Pressure-increases with depth, however, present a far more complicated and difficult problem. The stress distribution can only be postulated since measurement of stresses in rock in situ is at present only in the initial stages of development.
