On the possibility of reducing the solution of the doubly connected problem of mutual influence of two mine workings to a singly connected one
Authors:
Abstract
In the practice of maintaining mine workings there are often cases of their mutual influence. Especially significant is the impact of extraction operations on the stress state in the vicinity of development openings. The solutions of these problems are complicated and cumbersome, and therefore they are mainly available for cases of mutual influence of openings of the same shape. Only some solutions for different shapes are known. However, these solutions due to the complexity of the final formulas have not become widely used to determine the stresses in the vicinity of openings. It is necessary to create simpler calculation methods.
