ABSTRACT
On results mine researches dependence of stability index of the main and development workings is got on their general extent. Influence of the generalized index of workings’ stability is set on the relative monthly longwall’s power. Nonlinear dependence of relative prime price of coal is set on general length of the supported workings.
