FIELD: mining. SUBSTANCE: mining excavation is started near one end of breakage face and stopped at a distance equal to summarized width of dynamic and stationary support pressure zones formed by the effect of coal excavation by miner and developing working at opposite face end. Then the coal miner is moved along non-worked out section up to developing working. Then coal miner excavates non-worked out band in return direction. EFFECT: higher stability of rocks. 3 dwg
