基于椭圆画法原理在三心拱巷道施工中放样的可行性研究

Feasibility Study of Fast Construction Lofting in Three Center Arch Roadway Based on Ellipse Drawing Principle

在煤矿三心拱形断面巷道施工中,对三心拱巷道进行放样和工程质量验收是一个难题,为了研究三心拱巷道快速放样和测量的方法,通过对三心拱巷道与椭圆弧巷道误差分析,提出在三心拱巷道中采用椭圆画法的原理进行快速放样和测量是可行的,解决了煤矿在三心拱巷道掘进中施工放样和施工质量检查时测量的难题。

In order to study the method of fast lofting and measurement in three center arch roadway, through the error analysis of three center arch roadway and ellipse arc roadway, the feasibility of fast lofting and measurement method based on ellipse drawing principal was analyzed for three center arch roadway, achieving positive result. The measurement difficulty was solved for the lofting and quality inspection in coal mine tunneling of three center roadway.
