矿山一井定向内业解算的优化处理

Optimization of Processing of Office Operation Solution for Mine One Shaft Orientation

一井定向在外业测量条件不太理想的情况下(联系三角形的图形条件较差),联系三角形的内业解算采用不同的方法(正弦法和余弦法),得到的角度值会不一样,有时会相差较大(达到几分)。为此,通过对上述几种方法进行分析讨论,并进行筛选、优化、组合,最终获得最优的联系三角形解算方法(正余弦组合法)。

Conditions of one shaft orientation underground surveying is not ideal conditions （Connection triangle graphics could be of unlikeliness）. Office operation solution of connection triangle using different methods （ sine and co- sine method）gets the angle value couldn＇t be the same. Sometimes it will be a big difference（ there is difference of a few of minute of a angle value）. Therefore through analysis of and discussion, and filtering, optimization, combination, and then the paper obtains the optimal method of connection triangle solution（ Sine and cosine combination method）. So as to get the best solution results.
