杭来湾井田坐标系统的转换与总结

Transformation and summary of coordinate system in Hanglaiwan mine field

杭来湾井田采用北京1954坐标系统在实际工作中存在诸多不便,尤其在井田边界由于长度变形较大,不采取测量措施将有可能造成测量事故。随着CGCS2000坐标系统的应用,该系统精度高、应用范围广的优势逐步体现,相邻矿井边界可完美衔接。目前,关于坐标系统转换的文章较多,但是绝大多数是从理论角度出发,主要针对点位坐标进行转换,应用性较差,粗差不好控制。本文采用平面四参数模型,利用COORD软件实现了杭来湾井田北京1954坐标与CGCS2000坐标间的批量互转功能,具有操作简单、使用方便的优点,在实际工程中具有重要参考意义。

Hanglaiwan mine field uses Beijing 1954 coordinate system,which has many inconveniences in the actual work.Especially in the mine field boundary,due to the large length deformation,it is possible to cause measurement accidents without measurement measures.With the application of CGCS2000 coordinate system,the advantages of high precision and wide application range are gradually reflected,and the adjacent mine boundary can be perfectly connected.At present,there are many articles on coordinate system conversion,but most of them are from the theoretical point of view,mainly for point coordinate conversion,with poor applicability and poor gross error control.In this paper,the plane four parameter model was used,and the batch mutual conversion function between Beijing 1954 coordinate and CGCS2000 coordinate in Hanglaiwan mine field was realized by using COORD software.It had the advantages of simple operation and convenient use,and had important reference significance in practical engineering.
