Description
пачки 4 разновидностей и с отставанием в пространстве вдоль линии 01чистного забо таким образом, чтобы расположение раздробленных взрывом разновидностей 5, 6 соответствовало расположению их в массиве пласта. Отбитую горную массу скрепируют по всей длине очистного забо последовательно начина с раздробленных разновидностей; 5 верхней пачки.packs of 4 varieties and with a lag in space along the line 01 of the clean-up slab so that the location of the exploded fragmented varieties 5, 6 corresponds to their location in the reservoir massif. Repulsed rock mass is fastened along the entire length of the clearing slab sequentially beginning with crushed species; 5 top packs.
Предлагаемый способ выемки позволит повысить эффективность ее за счет инсификации процессов и улучшить услови поддержани кровли.The proposed method of excavation will increase its efficiency due to the insification of processes and improve the conditions for maintaining the roof.
