摘要
通过在12112运输巷过121集材立交处应用无岩柱施工技术,从根本上解决进、回风巷道立交施工期间各生产系统相互制约影响的矛盾,同时消除了过立交掘进工作面顶板易冒落的隐患。
By using non rock pillar roadway crossing construction technology ,extracted 12112 transport roadway passing over 121 concentrated material, fundamentally solve the mutual restraint contradiction of the production system overpass construction period of intake, return roadway, at the same time and eliminated the hidden dangers of roof falling during roadway tunneling.
