摘要
介绍了用一种简易激光指向器改装经纬仪 ,使普通经纬仪带有激光指向器。这种仪器使用前方交会法 ,很方便简洁地解决了测量人员不能进入的井下危险采场的空间位置和空间量的测量问题 ,并通过对该方法的精度分析 ,论证了其可行性和有效性 ,对井下各种危险空间测量具有广泛的推广前景。
An improved theodolite fixed with a simple laser direction indicator was introduced.Using it and the intersection with angles,a problem of measuring the spacial position and volume of an underground dangerous stope into which measuring persons aren′t permitted to enter can be easily solved.At the same time,the feasibility and the effectiveness of the measuring method are demonstrated through its accuracy analysis.This measuring method is full of promise to the measurement of various dangerous spaces underground.
