[0058] The coal gangue underground sorting and in-situ filling engineering design method of the present invention comprises the following specific steps:
[0059] The first step is to analyze the selectability of coal gangue, economic cost, sorting quality requirements and use of gangue: according to the gangue content, particle size, hardness, shape and density, the selectability of the sorting object is initially analyzed, and the estimated The economic cost of coal gangue sorting, clarify the sorting quality requirements and the use of sorted gangue;
[0060] The second step is to determine the coal and gangue separation method: combined with the coal and gangue separation capacity Q required by the mine k , according to the selectivity of coal and gangue and the adaptation characteristics of the sorting method, the optimal coal and gangue sorting method is selected; considering the coal and gangue sorting ability of different coal and gangue sorting methods, the optimal so...
