METHOD FOR MINE DEVELOPMENT OF DEPOSITS, SEPARATION OF ROCKS, FILLING OF MINED SPACE AND DRESSING OF ORE

摘要

FIELD: mining.;SUBSTANCE: present invention discloses a method of mine development of deposits, separation of rocks, filling of mined space and dressing of ore, including main sources of waste rock on working surface of small-scale development and measures to reduce level of development of waste rock; system design, equipment and separation technology for separation of coal bed empty rock; design of the system, equipment and technology for development of efficient works on a mining cavity with caving of a coal bed for simultaneous production of stowing coal; pre-treatment (enrichment) and environmental impact control measures before and after filling the waste rock into the mined-out space; as well as the principle and stages of designing "development, separation, filling and dressing" of mine development method of deposits. Method solves problem of gangue transportation over long distances, reduces costs for lifting of underground gangue and reduces pressure at mine auxiliary lifting installations and ground installations for coal benefication by washing, but also enables efficient treatment of coal mine waste, reduces the surface area of coal bed waste, reduces damage to the environment of the development site, and thereby protects the environmental medium.;EFFECT: filling of waste rock and effective extraction of working surface of coal bed have high efficiency of single process, which corresponds to requirements of modern mines to production efficiency, and also have wide application in perspective.;7 cl, 4 dwg
