Abstract
Under the stability of rocks is understood their property to form stable outcrops during the sinking of mine workings. Stable is considered to be such a state of the exposed unfastened section of the rock massif, in which during the necessary period of time under the conditions of production rocks do not collapse and do not slide, and the exposed surface or its part is displaced within the permissible limits. ...
