Abstract

The invention belongs to the technical field of coal mining, and provides a coal mine associated ore deposit mining method. The coal mine associated ore deposit mining method comprises the following steps that a coal mine deposit and a coal mine associated ore deposit are mined at the same time to obtain an original coal seam product; the original coal seam product is sorted for the first time to obtain a primary coal mine product; and the primary coal mine product is sorted for the second time to obtain a coal product and an associated mineral product. According to the coal mine associated ore deposit mining method, the coal mine deposit and the coal mine associated ore deposit are mined at the same time, and gangue, coal mine and associated ore are separated out by comprehensively applying impact crushing, sieving, gravity separation and other sorting hand sections; and the problem that in the prior art, after coal mining, a coal mine associated ore deposit is difficult to mine and utilize is solved, associated mineral resources are efficiently utilized, comprehensive utilization of the resources is facilitated, and the maximum benefits of economy, society and environment are obtained.

Description

technical field [0001] The application belongs to the technical field of coal mine mining, and in particular relates to a mining method of coal mine associated deposits. Background technique [0002] With the adjustment of the energy industry structure and the sustainable development of the national economy, it is imperative to do a good job in the comprehensive utilization of resources and environmental protection. [0003] There are many types of paragenetic and associated minerals in coal-bearing strata and coal seams in my country. Coal-bearing strata include kaolinite (soil), refractory clay, bauxite, bentonite, diatomite, oil shale, graphite, iron ore, gypsum, anhydrite, quartz sandstone and coal-derived gas; coal-bearing strata There are limestone, rock salt and mineral water in the basement and caprock. These minerals are widely distributed and rich in reserves. Coal-measure strata associated mineral resources mostly exist in the form of gangue in coal seam, roof,...
