摘要： The present invention relates to an automated continuous haulage apparatus and method designed for use in underground environments. Each mobile bridge carrier (10) contains distance measurement (70) and angular position (74) means for determining the mobile bridge carrier's (10) position and the angular position of attached piggyback conveyors (30). Means for determining the ceiling height (76) are utilized to adjust the height of the piggyback conveyors (30). On each mobile bridge carrier (10), input from the various sensors is received by an electronic controller (80) that calculates the position and orientation of the bridge carrier (10) and attached piggyback conveyors (30). The controller then plans an optimal path of movement for the bridge carrier (10) and computes the rate of movement for each independently operated track assembly on the bridge carrier such that the bridge carrier (10) and piggyback conveyors (30) arrive as close as possible to the planned path.

摘要： Embodiments of the present invention are directed to a method and apparatus for safety protection control of temporary roof support. In one embodiment, a temporary roof support has a load sensing member. In another embodiment, a beam structure of temporary roof support is supported by a load sensing pin. Strain gages are installed within the pin to measure the load placed upon the pin. An unusually high load being sensed by the pin indicates that the roof has fractured and the temporary roof support is supporting loose rock. In one embodiment, when an unusually high load is measured at the pin, the temporary roof support controls at the front of the machine are disabled. A second set of remotely located temporary roof support controls remain operative. In one embodiment, the second set of controls is located at the rear of the machine.

摘要翻译：本发明的实施例涉及一种用于临时屋顶支撑件的安全保护控制的方法和装置。在一个实施例中，临时屋顶支撑件具有负载感测构件。在另一个实施例中，临时屋顶支撑件的梁结构由负载传感销支撑。应变计安装在引脚内以测量引脚上的负载。由销检测到的异常高的负载表示屋顶已经断裂，临时屋顶支撑件支撑松散的岩石。在一个实施例中，当在销处测量异常高的负载时，机器前部的临时屋顶支撑控制被禁用。第二组位于远程的临时屋顶支撑控制器仍然可操作。在一个实施例中，第二组控制器位于机器的后部。
