摘要
针对近几年来煤矿井巷大型竖曲线测量标定和工程使用中存在的问题 ,根据曲线方程理论 ,提出了一种简单易行的新方法 ,即方程铅垂法。用这种方法可求出弦腰线上任一点距竖曲线巷道底板的铅垂距离 。
According to the problems presenting in surveying vertical curve in coal mine and its use in projects we bring forward a new method—equation plumbous which is simple and easy to use according to curve equation theory.It can gain the perpendicular distance of chord and band course,consequently improving the precision of laneway’s forming and examing its quality conveniently.
