Zusammenfassung:FIELD: mining industry; applicable in mining of medium-thick moderate and medium-dipping coal seams. SUBSTANCE: method of mining of medium thick bedded deposits includes preparation of inclined mining field for mining by long pillars along the strike, driving of vent and haulage drifts. Formed below haulage drift through coal pillar with lead and incline towards opening workings is chamber whose width shall accommodate working member of mining complex. EFFECT: higher intensity of preparation and mining of inclined mining fields, normal water drainage in driving of haulage drift. 3 dwg
