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。
Aiming at the problem of the rocking movement of coal mining in the high angle coal seam, based on the model of the spherical fly gangue and taking into account the fluctuation of the floor of the contact working face, according to kinematics and dynamics principle, the slope is plane and undulating 2 Kinds of circumstances under the gangue motion trajectory formula. Finally, an example is given to verify the feasibility of this method.
