FIELD: mining industry. SUBSTANCE: this relates to development of small-scale placer deposits with high incline of bed. Method implies preliminary arrangement of basin, formation of water reservoir in basin and location of float-carried platform in it. Mounted on platform are interconnected mining mechanism and benefication equipment. According to method, productive seam is mined, loosened rock is washed, rock mass is subjected to benefication, and tailings are stored in worked-out space. Float-carried platform is moved by longitudinal and lateral movements relative to placer deposit by means of hydraulic reactive jet. Mining mechanism mounted on float-carried platform is moved in parallel to front of cutting face. EFFECT: high efficiency. 3 dwg |
