Abstract: The efficient and high-quality development of underground roadway excavation is an important guarantee to improve
the comprehensive efficiency and benefit of mine operation. Taking this as the starting point, combined with specific engineering
examples, this paper analyzed and explored the rapid tunneling operation of mine bottom extraction roadways. Based on the
analysis of the actual demand of mine roadway excavation, it analyzed the optimization of roadway excavation, made a
comprehensive exploration on the process parameters and excavation scheme of rapid excavation construction, and summarized the
rapid excavation scheme of bottom extraction roadways suitable for the actual mine production. The actual verification shows that
through the application of the new scheme, the excavation efficiency of bottom extraction roadways is increased by more than 45%
on average, which plays a positive role in promoting the improvement of production efficiency.
