本发明公开了基于位姿监测和动作判别的放煤机构及控制方法，包括底座和顶梁，顶梁的前端连接有前梁且后端连接有掩护梁，掩护梁的后端连接有尾梁，尾梁的后端连接有插板，尾梁底部设置有尾梁限位千斤顶且插板底部设置有插板限位千斤顶，还包括控制器，尾梁限位千斤顶上设置有第一磁致伸缩位移传感器，插板限位千斤顶上设置有第二磁致伸缩位移传感器，尾梁钢板上设置有γ射线探测器，控制器控制放煤机构保持以期望的放煤口开口度大小进行放煤，同时控制器采集γ射线探测器的数据判断是否终止放煤。实现各支架整体姿态和放煤机构局部位姿的精确监测，保持以期望的放煤口开口度大小进行放煤，从而最大化顶煤回收率和经济效益。 The coal caving mechanism comprises a base and a top beam, the front end of the top beam is connected with a front beam, the rear end of the top beam is connected with a shield beam, the rear end of the shield beam is connected with a tail beam, and the rear end of the tail beam is connected with an insertion plate. A tail beam limiting jack is arranged at the bottom of the tail beam, an insertion plate limiting jack is arranged at the bottom of the insertion plate, a first magnetostriction displacement sensor is arranged on the tail beam limiting jack, a second magnetostriction displacement sensor is arranged on the insertion plate limiting jack, and a gamma ray detector is arranged on the tail beam steel plate. The control
