Zusammenfassung:FIELD: mining industry. SUBSTANCE: this method relates to mining minerals when deposits are lying deep or in hill sides. According to method, opening of mineral deposit is effected by underground workings with application of vertical ore chute which is located in center of ore field. Mining is performed by inclined layers at incline which is not less than incline angle at which ore is moving towards ore chute by gravity. Layers are worked successively from top to bottom in circular passes. Aforesaid method of mining allows for intensification of mining operation at reduced cost due to wider use of gravitation force. EFFECT: higher efficiency. 1 dwgg
