联系四边形法是矿井定向测量的连接方法之一。矿山测量技术规程规定:地面和井下无论采用何种连接方法,其预计的中误差不得超过±30"。因此,预先计算联系四边形法的连接误差,是联系四边形法中的一个主要问题。联系四边形法的连接误差计算方法有两种:一种
Contacting the quadrilateral method is one of the methods of connection for mine orientation measurement. The technical specification of mine surveying stipulates that no matter what kind of connection method is used, the predicted error should not exceed ± 30%. Therefore, pre-calculating the connection error of the tetragon method is a major problem in the tetragon method. There are two ways to calculate the connection error of a quadrilateral method: one
