Abstract
The complex method of a substantiation of ways maintenan to stability of local development excavations in overworked layers is offered. The mark of expected displacement of breeds contour of section local preparatory developments overworked layers is executed. Recommendations about realization overworked systems of working out in the conditions of mine «Raspadsky-koksovaja» are made. Necessity carrying out of developments of 2nd layer with backlog from a clearing face of 1st layer is proved. The mark of influence of parameters of an applied way maintenan to stability of developments on level of production costs is executed.
