超高水充填工作面俯采充填探讨

Discussion on super high water working face down-dip mining filling

邢东矿1129工作面设计为仰采,由于受断层影响,工作面两巷在掘进过程中均遇到前上断层,为顺利通过断层,两巷均是上山通过断层,造成工作面回采推进过程中有40 m俯采段,且工作面倾角局部处为26.5°,为保证充填体稳定,本文通过调整配比,对充填支架隔板进行调整等方法,使工作面顺利通过俯采段。

1129 working face of Xingdong Mine was designed to up-dip mining, in order to go through the upward fault,with, 40 m down-dip mining and working face inclination angle 26.5°, the ration of filling body and filling plate were adjusted.
