Mineral aggregate mechanized continuous production method

Abstract

The invention relates to a mineral aggregate mechanized continuous production method. The method comprises the steps that the area where to-be-exploited mineral aggregate bodies are located is explored firstly to form an underground seam model, mineral aggregate grade level distributing situation data is obtained, primary parameters of mineral aggregate exploitation equipment are determined, a mine shaft is exploited, fitting exploitation equipment is arranged, and continuous exploitation is conducted; when the continuous exploitation is conducted, different seams are divided on a working surface exploitation mine wall according to the difference of mineral aggregate grade levels, or one or more working sections are transversely divided simultaneously, one-by-one seam exploitation is conducted on the working surface exploitation mine wall by using a mining machine according to the sequence from high mineral aggregate grade levels to low mineral aggregate grade level or the mining machine is used for exploiting the working sections one by one in the moving process from one end of the working surface to the other end of the working surface, and the seams are exploited one by one in each working section according to the sequence from high mineral aggregate grade level to low mineral aggregate grade level. The method has the advantages that the grade level of the mineral aggregatescan be improved, the refining cost is reduced, the exploitation economical performance is good, and the method can adapt to the exploitation of hard mineral aggregates with different hardness levels.

Description

technical field [0001] The invention relates to a method for mechanized continuous production of ore materials, which is especially suitable for underground mining of hard materials. Background technique [0002] The existing mining method of hard material ore bodies such as bauxite and alumina rock is blast mining, which has low production efficiency, high mineral material dilution rate, difficult transportation, high refining cost, and cannot guarantee safe mining, and some even seriously affect The mining economy can no longer meet the requirements of modern mines and refining systems. Contents of the invention [0003] The invention aims to provide a mechanized continuous production method of ore material, which can improve the grade of the ore material, reduce the cost of refining, and has good mining economy, and can adapt to the underground mining of hard material mine beds with changing conditions. [0004] Main technical scheme of the present invention has: [0...
