FIELD: mining. ^ SUBSTANCE: invention relates to uncovering and preparing ore zones and lifting-transport plants, and can be used in mining industry, for example, in development of ore fields with small reserves. Method incorporates construction of inclined shaft, uncovering workings of production levels, laying guiding rails over them, using lifting machines and lifting vessels at ore output. Uncovering workings of production level enter ore zone in inclined manner at an angle, which is smaller than inclination of uncovering shaft, and in the ore zone they are connected with workings of haulage levels by accumulating rise or reloading chambers. Also a lifting-transport plant is proposed, which includes a connecting platform implemented in the form of rigid frame made of curved guiding rails and gimbaled in the soil of inclined workings of production levels, while angle pulleys are installed in the roof of joints of inclined shaft and workings of production levels. ^ EFFECT: extension of operating capabilities when uncovering ore zones with inclined shafts. ^ 3 cl, 3 dwg |
