Determenation of the bolting parameters under conditions of the zonal disintegration of rocks around underground workings

Recently the phenomenon of zonal disintegration of rocks had discovered at around underground workings at great depths. The main element of this fault concentric system that paralleled working profile.  The paper presents the method and formula determination of the bolted mine workings developed on stress-deformed rock massif at great depths at zonal disintegration of rocks around un-derground workings.

Aspects of coal strata mining at the mine of the elegest deposit (the republic of Tyva)

The Article considers the aspects concerning the mining of coal strata, prediction of the influence zones parameters of the primary extraction of thick seam “Ulug” on the overlying stratum. With due account of geological conditions of the seams occurrence and strength properties of rocks the recommendations are given on rational methods of the seam “Ulug” mining and on roof control in production faces as well as on support of development workings at the undermined seams.
