FIELD: mining industry; applicable in mining of sheet minerals. SUBSTANCE: pillar-and-board mining method includes mining of pillar by full advance of powered mining complex with subsequent separation of the complex into two parts with their turning through 180 deg and mining of adjacent pillars by retreating. Separated into two parts complexes are turned through 180 deg in opposite sides with respect to each other. EFFECT: higher efficiency. 3 cl
