硬岩巷道快速施工关键技术及其施工工艺研究

Research on Hard rock Tunnel Excavation Rapid Construction Key Technology and Its Construction Technology

东欢坨矿硬岩巷道施工缓慢,严重影响矿井生产。本文利用理论研究、实验测定等方法和手段对东欢坨矿硬岩石门巷道的围岩物理性质进行了细致、系统性的实验和研究。以"新奥法"为主要依据和基础,设计提出了硬岩石门巷道快速施工工艺和技术,提高了巷道掘进速度,对深部煤炭开采有重要意义。

Donghuantuo Coal Mine＇s hard rock tunnel construction is slow, which seriously influences mine production. This pa- per conducts detailed and systematic experiments and researches on the physical properties of surrounding rock of Donghuantuo Coal Mine＇ s hard rock crosscut tunnel by means of theory research and experiment measuring. Based on NATM method, the technique and technology of rapid construction in hard rock crosscut tunnel is designed and presented, which improves the speed of tunnel excavation and has significance on deeper exploitation of coal mine.
