摘要
结合具体的工程实例,从司钻技术、测量放线、周边孔司钻、底板孔司钻等方面对超欠挖施工技术在液压凿岩台车开挖巷道控制中的应用进行深入分析和研究。液压凿岩台车开挖巷道改后后,能大幅下降巷道超挖,周边变得基本圆滑、平顺,确保了炮孔间有着均匀的间距,取得了非常好的效果。
Combined with practical engineering examples, from the technology, measurement line, peripheral hole driller, bottom hole driller and other aspects of the overbreak excavation technology application of roadway control in hydraulic drilling rig in-depth analysis and research. After excavation of hydraulic drilling rig after, can greatly reduce overbreak, become the basic surrounding smooth, smooth, ensure the hole with uniform spacing, and achieved very good results.
