摘要： 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。

Abstract: In order to study method of speedy lofting and measurement at three heart arch roadway, It is possible using method of drawing ellipse for fast lofting and measurement through the analysis the error of ellipse arc arch and three heart roadway.It is solve the problem of measuring of fast lofting and examinating quality of construction at three heart roadway in coal mining. It is positive significance for promote fast lofting and measurement of three heart arch roadway at the tunneling working surface. Key words ：three heart arch;ellipse arc arch;fast lofting;measurement;roadway.
Key words: three heart arch, ellipse arc arch, fast lofting, measurement, roadway
