摘要
针对膏体充填回采工艺要求,设计了前后分体式ZGTC12400/30/50型膏体充填液压支架;该充填支架与传统一体式支架相比,既满足高产高效的生产要求,同时又实现了采空区充填的效果,真正达到了采煤与充填平行作业的目的,为解决我国"三下"压煤问题,提供了设备保障。
According to the technology of paste-filling and mining, the support of fore and back type ZGTC12400/30/50 are designed. Compared with the common support, the support can not only meet high productivity and efficiency requirements, but also achieve goal filling, and can solve coal cutting under building, railway and waters, providing reliable equipments.
