Abstract

The invention discloses a method for evaluating filling characteristics of filling coal mining hydraulic supports, and belongs to solid filling coal mining evaluating systems. The method particularly includes steps of A, analyzing geological data and geological conditions; B, initially selecting frame types of the hydraulic supports; C, determining initial selection schemes for foundations; D, determining indexes for evaluating the filling characteristics of the filling coal mining hydraulic supports; E, constructing framework models by the aid of Pro / E, Solidworks or CATIA three-dimensional software and simulating movement to obtain matrixes for evaluating the filling characteristics; F, comprehensively evaluating the filling characteristics of the filling coal mining hydraulic supports by the aid of the multiple indexes and determining the optimal schemes. The method has the advantages that each filling coal mining hydraulic support is one of important solid filling coal mining devices, the initial schemes are determined and optimized by the aid of computer technologies by control variable processes, the optimal schemes are determined by analytic hierarchy processes, accordingly, a scientific and reasonable evaluation system and specific, feasible, comprehensive and simple support optimization processes can be provided for extensive related personnel such as scientific research workers and engineers who engage in filling coal mining hydraulic support optimization, and the design, research and development time can be shortened to a great extent.

Description

technical field [0001] The invention relates to an evaluation system and method for coal mining with solid filling, in particular to a method for evaluating the filling characteristics of a hydraulic support for coal mining with filling. Background technique [0002] Comprehensive mechanized solid filling coal mining technology is a green mining technology that utilizes fully mechanized filling mining equipment to densely fill solid waste (gangue, fly ash, loess, aeolian sand, and construction waste, etc.) into the goaf of the coal mining face. As the core equipment of this technology, the hydraulic support for filling coal mining not only supports the roof, pushes the conveyor and shearer on the working face, but also undertakes the tasks of filling the goaf, assisting material transportation and compaction. The reliability of its performance is dense filling. key. [0003] The design and R&D of traditional filling coal mining hydraulic supports are based on physical proto...
