现在,矿床地下开采和矿岩运输已广泛采用各种无轨车辆。最初,无轨设备只限于用在有直接通道的作业区。在矿床边缘地带或易于冒顶的区段,由于司机的作业安全无保障,往往不用无轨设备采矿。由于控顶是必不可少的先决条件,这意味着必须可靠地加固顶板,以确保设备安全,因此金属矿、钾盐矿或煤矿最初往往用 Various types of trolley-less vehicles are now widely used in underground mining and ore transportation. Initially, trackless equipment was limited to work areas with direct access. In the margins of the deposit or in areas prone to roof caving, mining is often not carried out using trackless equipment due to the insecure operation of drivers. Since roof control is an indispensable precondition, it means that the roof must be reliably reinforced to ensure the safety of the equipment so that metal, potash or coal are often used initially
