FIELD: mining.
SUBSTANCE: invention relates to the mining industry and can be used to openly develop small coal mines and to obtain by classification directly in the process of mining sorted coal, ensuring its safety and energy properties by packing fuel in containers for delivery to remote consumers located in the northern regions, including the Arctic. Method for the open development of solid mineral deposits includes the production of conditioning fractions by means of a continuous excavation and classification process with stripping by stratification in a stratified stratum of a mineral deposit, supply of rock mass from the working body of the mining complex directly to the classification unit. By means of an automatic system, the separated coarse fraction and fine fraction are periodically fed into soft containers through hopper compartments after the soft container is installed by means of an automatic packaging device equipped with a pivoting mechanism. After filling the soft container controlled by the automatic system, the automatic packaging device seals the soft container, disconnects it from the nozzle and sends a signal to the drive of the rollers of the platform to guide the soft container over the overpass under the action of gravity on the face of the face.
EFFECT: technical result of the proposed method is to increase productivity and technological efficiency by combining operations in extraction, sorting and differentiated packing of minerals in the mining complex.
