1、引言在工作面倾角大、仰采角度大等条件下,仰斜开采工作面的顶板控制显得非常重要。当仰斜角大于12°时,工作面顶板的拉破坏及向采空区方向的下滑分力将给工作面的安全生产造成很大影响,合理确定仰采条件下的支护参数,有效控制工作面顶板是安全顺利开采的重要保证。
1. INTRODUCTION Under the conditions of large dip angle and large angle of Yang mining, it is very important to control the roof of inclined mining face. When the elevation angle is greater than 12 °, the pulling failure of the working face roof and the downward force component to the goaf will have a significant impact on the safety of the working face, and the support parameters under the condition of Yang mining can be reasonably determined and effectively controlled Working face roof is an important guarantee for safe and smooth mining.
