DEVELOPMENT METHOD OF GRAVEL DEPOSITS OF MINERAL RESOURCES |
摘要 |
FIELD: mining. ^ SUBSTANCE: method involves delineation of balance and industrial reserves as per the data of exploration wells, drilling and mining activities; re-delineation of industrial reserves is performed after their delineation along the top of sands. At that, new contour at excavation of rock mass is set from cross point of exploration well with initial contour of industrial reserves at minimum elevation of balance reserves as to top of bed of sands to cross point of contour of balance sands-peat reserves at an exit angle of excavating transport vehicle of stripping equipment, and where there are no cross points of new contour with contour of balance reserves as to top of bed of sands - parallel to initial contour of industrial reserves. ^ EFFECT: reducing operating losses of useful component. ^ 1 dwg |
