大采高垛式液压支架设计
Design of high cutting chock type hydraulic support
摘要
Abstract
In view of problems of poor support effect,slow support speed,high support cost and great labor intensity of advance support with advanced hydraulic support,single hydraulic prop or timber in return airway of fully-mechanized high cutting coal mining face of a coal mine in Yulin mining area,a high cutting chock type hydraulic support was designed.Finite element analysis of the support was conducted under three kinds of operating conditions namely top beam eccentric load and pedestal torsion,top beam torsion and pedestal concentrated load,top beam concentrated load and pedestal eccentric load.The stress nephogram and deformation nephogram show that the whole support is stressed uniformly without apparent stress concentration phenomenon and large deformation.The field test result show that the support can effectively guarantee safety of working face roadway with small deformation of surrounding rock of roadway.关键词
