A kind of filling with fully mechanized mining is mixed adopts face transition bracket supporting parameter design method

2016 
It is mixed the invention discloses a kind of filling with fully mechanized mining and adopts face transition bracket supporting parameter design method.First according to mixed mining working face coal mining production capacity and filling section working face stowage capacity demand, hybrid working face total length L is determined Always With filling segment length L It fills ;Then, filling and fully mechanized mining mixed mining numerical model are established by 3DEC 3 d-dem meta software, simulation calculates filling section goaf difference Full Ratio When variation, changeover portion roof caving height H and changeover portion influence range of stress S;Based on numerical simulation calculation as a result, pressing coefficient R 2 Curve is fitted to obtain Full Ratio With the functional relation for being caving height H, changeover portion influence range of stress S;Finally Practical Project geologic parameter is combined to be designed transition bracket supporting parameter.This method can design for bracket support and provide reference, realize hybrid working face filling bracket and fully mechanized mining supporter smooth transition, and further abundant filling coal mining is theoretical, expand the application range of filling coal mining.
