Title:
FULLY MECHANIZED MINING-FILLING MIXED MINING WORKING FACE FILLING SECTION LENGTH DETERMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/101634
Kind Code:
A1
Abstract:
Disclosed is a method for determining a length（ ）of a filling section in a fully mechanized mining-filling mixed mining working face (11). First of all, according to the production capacity requirement of a mine, a total length () of the fully mechanized mining-filling mixed working face is determined. Then, according to the principle that the daily production amount of gangue in a rock protection layer working face (10) is equal to the mass of filling material filled in a goaf of the filling section in the fully mechanized mining-filling mixed working face, a length range of working face of the filling section is preliminarily determined. Finally, the working face length of the filling section is determined according to the requirement of the development of overlying rock fractures and strata movement characteristics of the on-site fully mechanized mining-filling mixed mining working face. The method for determining is simple and practical, and can provide engineering and technical guidance for the popularization and application of the fully mechanized mining-filling mixed mining technology. It further promotes a "mining, selecting, filling and mining" integrated environment-friendly mining recycling mode, wherein the underground gangue in the coal mine does not go out of the mine, the gangue is cleaned, selected, and refilled into the goaf, and filling coal mining is efficiently implemented, so as to expand the scope of popularization and application of filling coal mining.
