METHOD FOR EVALUATING FILLING CHARACTERISTICS OF FILLING COAL-MINING HYDRAULIC SUPPORT

摘要

A method for evaluating filling characteristics of a filling coal-mining hydraulic support, implemented through the following steps: A. analyzing geological data and geological conditions; B. initially choosing the type of hydraulic support; C. determining basic initial schemes; D. determining indexes for evaluating filling characteristics of the filling coal-mining hydraulic support; E. constructing a framework model using Pro/E, Solidworks or CATIA three-dimensional software and simulating movement to obtain a filling characteristic evaluation matrix; and F. performing comprehensive evaluation through the multiple indexes and determining the optimal scheme. The filling coal-mining hydraulic support is one of important devices for solid filling coal mining, initial schemes are determined and optimized using computer technologies and through a variable control method, and the optimal scheme thereof is determined by using an analytic hierarchy method. The evaluating method is a scientific and rational evaluation system, and provides a specific, feasible, comprehensive and simple support optimization method, substantially reducing the design and development time.
