Abstract

The results of an investigation of practicable contours of horizontal underground mine workings and their safe laying depth are presented. The absence along the contour of points where the tangential normal stress exceeds the ultimate strength of the enclosing rock in tension and compression can serve as a criterion for determining the admissible depth.
