一、回柱绞车现状为了保证采煤工作面的安全和回采工作的顺利进行,工作面所占空间必须支护,而采空区也必须及时回柱放顶。回柱绞车就是用于回采工作面回柱放顶的专用设备。目前随着采煤机械化的发展,综合开采设备的利用,回柱绞车也逐渐用于液压金属支架的搬迁。我国回柱绞车的发展大致可分为三个阶段:五十年代仿制设计;六十年代开始自行设计;七十年代以后向系列化标准化方面发展。
First, the status quo column winch In order to ensure the safety of coal mining face and mining work smoothly, the work area must support the space, while the mined-out area must be timely back to the top column. Column winch is used for mining face back to the top of the column dedicated equipment. At present, with the development of mechanization of coal mining and the utilization of comprehensive mining equipment, the return winch is gradually being used for the relocation of hydraulic metal supports. The development of the return column winch in our country can be roughly divided into three stages: the imitation design in the 1950s, the design in the 1960s and the development of serialization and standardization in the 1970s.
