摘要: 在巷道掘进过程中,常需要施工超过一般巷道高度的“超高巷道”,一般的施工工艺是先掘进、后挑顶,增大
了工作强度。而如果边挑顶边掘进,则只需要进行一次顶板支护作业,减少了工作量和支护材料的使用量,极大地降低
了开采成本,从而达到一次安全快速成巷的目的。

Abstract: In the process of roadway excavation, it is often necessary to construct "ultra-high roadway" which is higher than the
general roadway height. The general construction technology is to excavate first and then rip the roof, which increases the working
intensity. If the roof is ripped while excavating, only one roof support operation is required, which reduces the workload and the quantity
of supporting materials, and greatly reduces the mining cost, so as to achieve the goal of a safe and fast roadway completion.

Key words: ultra-high roadway; excavating after roof ripping; roadway forming method
