矸石充填工作面关键技术探索与研究

Exploration and Research on Key Technology of Gangue Filling Face

针对现有矸石充填技术无法实现工作面采空区两顺槽的全部充填问题,古城煤矿创新性的探索实践气动力矸石充填联合采煤法,减少地表下沉,实现矸石不出井,减轻矿井提升运输的压力,有效实现了矸石充填工作面关键技术的突破。

In view of the fact that the existing gangue filling technology can not achieve all the filling problems in the goaf of the working face,the innovative exploration and practice of Gucheng Coal Mine pneumatic gangue filling combined mining method can reduce the surface subsidence,realize the gangue does not come out of the well,reduce the pressure of mine lifting and transportation,and effectively achieve the breakthrough of the key technology of gangue filling working face.
