An integrated system for shallow underground mining, selection and filling of lead-zinc mines

Abstract

The invention discloses an integrated system for underground mining, selection and filling in the shallow part of a lead-zinc mine, which includes an underground mining lifting and waste rock transfer system, an underground crushing system, an underground dressing plant system, a filling system and auxiliary production facilities, all of which are arranged in the shallow part In the stratum; the integrated system of underground mining, selection and filling in the shallow part of the lead-zinc mine adopts the joint development and transportation system of the mixed well and the ramp. connected, and has an independent ventilation system and a second safety exit. Only the exit of the ramp and the wellhead of the return air shaft are arranged on the surface, so there is no need to occupy new surface land for the construction of mining and dressing industrial sites, tailings ponds and other surface facilities, and the surface exit can be combined with the surface landscape design of the mining area. The system has better production Convenience, safety, and environmental protection have become a new mining development model.

Description

Technical field [0001] The present invention relates to a lead-zinc mine mining, a mineral distribution system, in particular to a leading portion of a leading part of a lead zinc mine. Background technique [0002] Lead zinc acts as an important colored metal to play a pivotal role in the development of the economy. With the continuous development and utilization of mineral resources, the development and construction conditions of lead and zinc mines are more severe, and the growing beauty of the society needs to be more and more than valuable contradiction between precious lead-zinc resources. Therefore, the pace of mineral strategy must move toward "deep" and "green mines", and the underground can be used as a new model of "mining development". [0003] As early as in the 1980s and 1990s in the United States, former Soviet, Peru, Sweden, Canada, Italy and other countries, the mining development was subject to the harsh surface environment and national defense safety, and the m...

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
