Underground coal mine working face mining, selecting and filling integrated system and use method

Abstract

The invention provides an underground coal mine working face mining, selecting and filling integrated system and a use method. Equipment and systems for screening, intelligent dry separation, gangue filling and matched transportation are additionally arranged on a working face, and raw coal screening, lump coal gangue separation and gangue goaf filling are performed in sequence, so that the underground working face mining, selecting and filling integrated system with underground coal gangue separation and onsite gangue filling is realized; the input end of an intelligent dry separation unit roadway is arranged on a main transportation roadway of the working face, the output end of the intelligent dry separation unit roadway is connected to the main transportation roadway and an air return roadway of the working face, the screening of clean coal and lump coal is effectively increased, the coal mining efficiency is improved, solid waste in coal briquettes is reduced, and the production efficiency of a mine is improved; and gangue is conveyed to a working face goaf through the air return roadway of the working face, so that solid waste treatment of the mine is effectively achieved, and economic benefits of the mine are guaranteed.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to an integrated system of mining, selection and charging for working faces in underground coal mines and a method of use thereof. Background technique [0002] As the basic energy for the development of my country's industrial society, coal provides the driving force for the development of my country's economy and industrial society. However, for a long time, the extensive production mode and serious environmental pollution have been the problems that plague the development of coal enterprises. In recent years, with the continuous improvement of the industrial level and equipment level, the country's increasing emphasis on intelligent and green advanced technologies, and the continuous deepening of the zero-tolerance attitude towards environmental protection issues, the traditional production model of the coal industry has put forward higher requirements. requirements. ...

AI Technical Summary

Problems solved by technology

[0004] In view of the serious ineffective transportation and lifting of a certain proportion of coal gangue in the processing of raw coal mining in the prior art and the formation of a large amount of solid waste such as coal gangue after ground washing, it has brought heavy solid waste to the mine. To solve the problem of waste disposal burden, the present invention provides an integrated system of mining, selection and filling in the underground working face of coal mines and its use method, which effectively screens gangue and clean coal, effectively solves the problem of solid waste discharge faced by mines, and reduces Environmental pollution caused by ground discharge of solid waste, economic and environmental benefits are very significant
