Embodiment Construction
[0025] The invention discloses an underground mechanized continuous falling ore beneficiation method, the core of which is to divide the mining wall of the working face into different layered regions (roughly horizontal Extended strip), "layered" conforms to the natural characteristics of mineral material distribution, so the layered area is basically divided according to the natural distribution characteristics of mineral materials, and then the mining wall of the working face is artificially divided into a Or multiple working sections, each working section is exactly a small working face mining wall unit. When mining, the drum type mining machine 9 is used to cut in from the beginning of the working face, advance along the working face until it reaches the terminal, and carry out mining one by one in the process of mining. In each working section, mining is carried out area by area according to the order of mineral grades from high to low. , and then distribute the falling m...

The invention relates to an underground mechanized continuous ore drawing beneficiation method. The method comprises the following steps: detecting mineral aggregate components of a working face ore body; carrying out region and working section division on a working surface according to grade grades; using a drum-type mining machine for mining working sections one by one from the starting end to the terminal end of a working face; carrying out regional mining one by one in each working section according to the sequence of the mineral aggregate grades from high to low; only reserving mineral aggregate at a lowest level of the top and a bottom step in each working section; returning the mining machine to the starting end from the terminal end; in the process, mining the mineral aggregate atthe lowest grade at the top and the bottom step section by section at a time, before the grade of the exploited mineral aggregate is about to be switched, controlling time-sharing conveying by a conveyor and split charging by a tail end discharging split charging machine through signal coordination, and conducting split charging on the falling mineral aggregate into different stock bins accordingto different grade grades of the mineral aggregate. According to the method, respective mining of different-quality mineral aggregates in a same working face is achieved, the mining profit is greatlyincreased, and particularly, the economical efficiency of hard and graded material mining is remarkably improved.
Description
technical field [0001] The invention relates to an ore-dropping ore dressing method, which belongs to an underground continuous mining method and can be used for underground mining of hard materials. Background technique [0002] Layered and segmented mining is proposed in the field of open-pit mining, mainly for thicker ore seams. Because the quality of mineral materials in different sections of different ore layers varies greatly, unified mixed mining will lead to serious mineral material dilution rate, high cost of refining beneficial components, and low mining cost. The benefit is very low, and different layers and different sections are mined separately and put into storage for refining, which can greatly increase the benefit of the enterprise. [0003] The existing open-pit layered and segmented mining is mainly completed by buckets, scrapers and other working face equipment supporting automobile transportation, etc., which has a large space and is easy to operate.
