Maqolada barcha qavat baladligiga o'tkazishda ikki varusda jovlashgcm burg'idab vetkazish qazilma jovi varianti ko'rib chiqilgan. Bu maqbul vo'qotish va aralashib ketish darajasida gorizontal tekislikda qazdma joylari orasidagi masofani oshirishga imkon beradi. Biryarusli variantdan farqli o'laroq markaziv o'qlar orasidag masofa oshib borishi bilan qazib olish sezilarli ravishda o'sadi.

The variant with two-storied arrangement o f drill haulage working with the release o f the full height o f the floor is reviewed in the article. This enables to increase the distance between the workings in the horizontal plane, while maintaining an acceptable level o f losses and dilution. In contrast to the single-storied variant, the extractions with an increase in axle spacing grow up significantly.
