为了解决国产岩石掘进机硬岩巷掘进中暴露出的问题,在EBH300(A)岩石掘进机过程中,进行了机械结构和机械功能等方面的创新设计,解决了切割机构振动问题,提高了切割减速箱的寿命,增强了装运机构的装运能力,解决了超掘和欠掘问题。通过在f≤13的岩巷掘进中实际应用,验证了该掘进机性能的可靠性,改变了爆破法开拓岩巷的落后生产工艺,提高了煤矿岩巷开拓的生产效率和安全性。
In order to solve the problems exposed in the hard rock tunneling of domestic rock roadheaders, the innovative design of mechanical structure and mechanical functions was carried out in the EBH300 (A) rock roadheader to solve the vibration problem of the cutting mechanism and improve the cutting Gearbox life and enhance the shipping capacity of the shipping agency to solve the problem of overdue and underdead. Through the practical application in the excavation of rock roadway with f≤13, the reliability of the performance of the roadheader is verified, the outdated production technology of blasting open up rock roadway is changed, and the production efficiency and safety of rock roadway open up are improved.
