大工作阻力放顶煤过渡液压支架小中心距应用研究

Research on Little Centre Distance Using of High Stress Caving Transition Hydraulic Support

针对大工作阻力放顶煤过渡液压支架中心距问题,以ZFG13500/22/35D型大工作阻力液压支架为研究对象,阐述支架中心距不足给液压支架设计过程带来的困难及解决办法,实现了大工作阻力放顶煤过渡支架小中心距的设计和应用。

Aiming at the issuesof centredistance of high stress caving transition hydraulic support,taking ZFG13500/22/35D high stress hydraulic support as the research object, expounded the difficulties and solves in the design process of hydraulic support because of centre distance insufficient.It realized design and using of little centre distance of high stress caving transition hydraulic support.
