In discussing coal mine entry construction with rock bolt technology, examinedthe craft and machinery problems as well as the conditions in which to use each kind ofmachine and tool.It exposed the intrinsic flaws of the widely used road header.The problemis that it was designed according to early timbering support state but is not suitable forrock bolt technology.The way to improve the function of existing road headers is notthrough parallel operations but using the SUDM (Shield Union Driving Machine), which isa new machine that improves construction.This article proposed a few solutions in designto solve this problem.
In discussing coal mine entry construction with rock bolt technology, examined the craft and machinery problems as well as the conditions in which to use each kind of machine and tool. It exposed the intrinsic flaws of the widely used road header. The problem is that it was designed according to early timbering support state but is not suitable for rock bolt technology. The way to improve the function of existing road headers is not through parallel operations but using the SUDM （Shield Union Driving Machine）, which is a new machine that improves construction. This article proposed a few solutions in design to solve this problem.
