Increasing rates of underground mining bring among the most important problem of control of stresses acting in the array.

The experience of using nuclear-geophysical methods of controlling the stressed state of the massif in solving the problems of mining production has allowed us to identify the main requirements to the measuring apparatus and equipment, non-fulfillment of which significantly limits the scope of radiometry ...

Along with the development and improvement of traditional methods of pressure determination, based on the study of elastic deformation values of rocks, various physical methods are increasingly used, including gamma methods of determining the density of rocks.
