1. Способ крепления горных выработок со слабыми породами кровли анкерной крепью, включающий бурение скважин в кровлю, при проведении выработок, формирование грузонесущей потолочины, закрепление в ней анкеров, отличающийся тем, что скважины в породах кровли бурят с опережением забоя на две заходки, из них скважины у боков выработки бурят наклонно с выходом их за контур отжима и опасных деформаций пород в боках на величину, равную 0,25-0,3 ширины выработки, нагнетают в скважины раствор твердеющей смеси и формируют грузонесущую потолочину по ширине выработки с выходом концов ее за контур отжима и опасных деформаций пород в боках на величину, составляющую 0,25-0,3 ширины выработки.1. The method of attaching mine workings with weak rocks of the roof with an anchor support, including drilling wells into the roof, during the workings, forming a load-bearing ceiling, fixing anchors in it, characterized in that the wells in the roof rocks are drilled ahead of the bottom by two entries, of which wells at the production sides are drilled obliquely with their exit beyond the extraction circuit and dangerous rock deformations in the sides by an amount equal to 0.25-0.3 of the production width, a solution of the hardening mixture is injected into the wells and a load-bearing ceiling is formed along the width other workings with the exit of its ends beyond the contour of the spin and dangerous deformations of the rocks in the sides by an amount of 0.25-0.3 of the width of the workout.
