Ground Pressure Characteristic Analysis of Hydraulic Breaking-off Prop on Working Face

介绍切顶支柱使用情况下的工作面矿压特性,分析切顶支柱对顶板管理的作用。切顶支柱的使用可以大大提高回柱放顶的效率,并且能够减少顶板事故的发生,为实现工作面的稳产、高产创造条件。

Introduce a pressure characteristic of working face with the usage of hydraulic breaking-off prop. It analyses the effect of this prop to the roof management. The usage of this prop can largely enhance the efficiency of taking back props and cutting down roof, and it also can reduce the occurrence of roof accidents. It paves the way for realizing the steady and high output on working face.
