大倾角煤层开采飞矸运动规律研究

Research on Rule of Flying Gangue in Steeply Dipping Seam Mining

针对大倾角煤层开采飞矸冲击运动问题,以球形飞矸运动模型为基础,并考虑了接触工作面底板有起伏的情况,根据运动学、动力学原理,推导出坡面为平面和有起伏2种情况下飞矸运动轨迹的计算公式。最后通过算例,验证了本文方法的可行性。

Aimed at the problem of shock motion of flying gangue in steeply dipping seam mining, based on the spherical flying gangue motion model, considering the contact working face floor usually has ups and downs and according to the theory of kinematics and dynamics, the motion trajectory of flying gangue has been deduced in two cases that the slope is plane and the slope has ups and downs. Finally, the feasibility of the method was verified through an example.
