Embodiment 1
[0019] Embodiment 1. This embodiment provides an analysis and evaluation method for the integrated design of underground mining, selection and filling in coal mines. The analysis steps are as follows:
[0020] 1) Since the layout of the coal preparation chamber group, the preparation of the filling material and the specific design scheme during the mining and filling process of the coal mine all have a great influence on the coal mine area, so this embodiment chooses the coal preparation under the coal mine The three influencing factors are the layout of chamber group, the layout of filling material preparation chamber group, and the integrated design scheme of mining, selection and filling as the evaluation index of the integrated design of underground mining, selection and filling;
[0021] 2) Based on the types of separation technologies such as selective crushing, dense medium shallow groove, and dynamic screen jigging, the modular design of the underground coal preparation...

The invention belongs to the technical field of coal mine filling mining, and relates to an analytical evaluation method of underground coal mine mining, separating and filling integrated design. Dueto the great influence of the arrangement condition of coal separation chamber groups, the condition of filling material preparation chamber groups, a specific design scheme and the like in the miningand filling process of a coal mine shaft on a coal mining area, the embodiment of the invention selects three influence factors including the arrangement of the underground coal mine coal separationchamber groups, the arrangement of the underground coal mine filling material preparation chamber groups, and the mining, selecting and filling integration design as evaluation indexes of the underground coal mine mining, selecting and filling integration design. According to the analytical evaluation method of the underground coal mine mining, separating and filling integrated design, the evaluation is carried out from three aspects of the arrangement of the coal separation chamber groups, the arrangement of the filling material preparation chamber groups, and the mining, selecting and filling integration design theme, the weight of each aspect can be adjusted according to the actual situation, and the analytical evaluation method of the underground coal mine mining, separating and filling integrated design is suitable for wide popularization and application.
Description
technical field [0001] The invention belongs to the technical field of coal mine filling and mining, and relates to an analysis and evaluation method for the integrated design of underground mining, selection and filling in coal mines. Background technique [0002] The "three-down" coal pressure is serious in the central and eastern regions of my country. Filling mining can safely and efficiently extract a large amount of "three-down" coal pressure, improve the resource recovery rate, extend the mine service life, and promote the sustainable development of the coal industry. . At present, more and more attention has been paid to the integrated filling mining technology of underground mining, selection and filling under the premise that the gangue does not go up the shaft. More than 10 mines across the country have carried out the practice of the underground coal gangue separation system and accumulated certain experience. The integrated design includes multiple key links of ...
