DETERMINING THE PATTERNS OF STABILITY OF MINE WORKINGS FOR CALCULATION ROOF BOLTING PARAMETERS

Purpose. The published studies are aimed at determining the mechanism of deformation rocks contour around workings in terms parameters emerging fracturing and their dependence on indicators strength depth occurrence massif. tasks study include installation fracture indicators, determination development process working, including effect longwall mining taking into account possibility reuse workings.
 Methodology. To solve set tasks, method field observations was used together with use regression dependencies to determine dependences influencing factors. In addition, full-scale pull-out tests anchor support used, which made it possible clamping forces anchors.
 Originality. course research, stresses along K7 coal seam conditions mine named after Kuzembaev CD JSC "ArcelorMittal Temirtau" for massif fastening. Rational roof bolting preparatory have been established. This type fastening provides direct contact between lining. Analysis results calculating showed that maintain workings, is necessary take bolting. main length anchors, total resistance density anchors. Anchor forms laminated rock beams rocks, ensure stability Conclusions practical significance. devoted establishment influence mining-geological mining-technical factors formation zones inelastic host were considered. Significant processes obtained, parabolic zone destruction determined. significance research consists actual required bearing capacity anchorage two levels k7 mine.
