Lead zinc ore shallow underground mining, separating and filling integrated system

Abstract

The invention discloses a lead zinc ore shallow underground mining, separating and filling integrated system. The lead zinc ore shallow underground mining, separating and filling integrated system comprises an underground mined ore lifting and waste stone transferring system, an underground crushing system, an underground separating plant system, a filling system and an auxiliary production facility which are evenly distributed in a shallow stratum. A mixed well and slope ramp combined development and transportation system is adopted in the lead zinc ore shallow underground mining, separatingand filling integrated system, the underground mined ore lifting system, the underground separating plant system, the filling system and the auxiliary production facility are connected with the groundthrough a slope ramp, and an independent ventilating system and a second emergency exit exist. Only a slope ramp outlet and an air return well mouth are distributed on the ground surface, there is noneed to occupy a new ground surface land to construct a mining and separating industrial side, a tailings pond and other ground surface facilities, a ground surface outlet can be combined with the mining area ground surface landscape design, and the system has high production convenience, safety and environmentally friendliness and realizes a new mining development mode.

Description

Technical field [0001] The invention relates to a lead-zinc mine mining and beneficiation system, in particular to a lead-zinc mine shallow underground mining, dressing and filling integrated system. Background technique [0002] As an important non-ferrous metal, lead and zinc play a pivotal role in economic development. With the continuous development and utilization of mineral resources, the development and construction conditions of lead-zinc mines have become more and more severe, and the contradiction between the growing need for a better life in society and the development of precious lead-zinc resources has become more apparent. Therefore, the strategic pace of the mining industry must move towards the fields of "deep ground" and "green mines", and the integrated underground mining, dressing and filling system must be adopted as a new model of "mining development". [0003] As early as the 1980s and 1990s, in the United States, the former Soviet Union, Peru, Sweden, Canada...

AI Technical Summary

Problems solved by technology

[0018] 1. This technology only integrates ore dressing crushing, ore grinding, gravity separation or flotation equipment, and does not integrate concentrated ore and tailings dense filtration equipment that covers a large area, nor does it integrate filling stations and water treatment facilities, so it is not considered real. An integrated system of mining, selection and charging;

[0019] 2. The technical equipment needs to be installed in the underground narrow roadway for equipment installation and beneficiation production. At present, the maximum production capacity of the equipment is 50t / h, and the scale production capacity is small

[0020] 3. This technology has no filling and water treatment equipment, and the transportation of technical slurry pipeline consumes a lot of energy and cannot realize water recycling

[0021] 4. The technology is deployed in the underground tunnel without a separate ventilation system, which makes the mining ventilation system difficult

The existing research and design of the integrated underground mining, selection and charging system is still at the research stage, and the construction difficulty and investment scale of the chamber group, the transportation and maintenance of large mineral processing equipment, and the infrastructure and production operation of the underground mining, selection and charging integrated system have not been fully considered. The convenience, safety and convenience of operators, safety and environmental protection requirements and other requirements cannot be implemented
