Abstract
This paper evaluates methods for strata control in gate roads used in the Komsomolets Donbassa mine with 2 coal seams from 1 to 1.1 m thick at depths of 418 m and 624 m, with dip angles from 5 to 10 degrees. Long pillars are mined by a system of longwall faces with caving. The following methods for strata control in gate roads are comparatively evaluated: use of blocks made of reinforced concrete, use of timber cribbings, combined use of concrete blocks or cribbings and strips of pneumatic stowing from 8 to 12 m wide, use of thin coal support pillars (from 2 to 3 m). Investigation results are shown in 4 diagrams. Analyses show that use of blocks made of reinforced concrete or concrete blocks combined with strips of pneumatic stowing does not prevent excessive roof subsidence and support deformation. Use of coal support pillars from 2 to 3 m wide is not recommended due to considerable cost and coal losses. Use of timber cribbings combined with strips of pneumatic stowing is most expedient. Recommendations on using timber cribbings and pneumatic stowing for strata control in gate roads used by the next longwall face are made. (In Russian)
