FIELD: mining.
SUBSTANCE: claimed process comprises the division of the bed into on-dip plies and development of every ply with division into mining slabs. Every mining slab is confined over the bed width by interslab airtight bridges and the boundary of the on-dip bed plies division into plies into levels. Coal muck is delivered to coal shoot and, further, via bottom gate to the mine loading complex. At division of on-dip ply into levels interlevel coal pillars are left on-dip height of which H (m) is defined from the expression: H≥(2.1-3.5)M, where M is the mining height (m). Interlevel pillars are erected artificially at preparation of mining slabs for development.
EFFECT: higher safety of development.
