煤矿井下为了有效防范、避免耙装机事故的发生,耙装机必须有防止耙斗出槽的护栏。在放炮时必须进行拆卸,防止放炮崩坏。针对这些问题,根据巷道的高低,设计了一种可以调节的新型耙装机护栏,从根本上解决了以上问题,并在神火集团新庄煤矿成功投入使用。 Coal mine in order to effectively prevent and avoid the occurrence of raking machine accident, rake machine must be installed to prevent rake bucket out of the fence. Must be disassembled when shooting, to prevent the shooting collapse. In view of these problems, according to the level of the roadway, a new type of rake-mounted guardrail that can be adjusted was designed, which fundamentally solved the above problems and successfully put into use in Xinzhuang Coal Mine of Shenhuo Group.
