摘要

Purpose of connecting surveys and orientation measurements is to determine mutual position of underground mine working andbuilding objects, situated on the surface and/or with other underground workings, situated on other horizons. Should a mine shaft isthe development working, it is necessary to project a surface point to connected horizon. With respect to required positioning accuracy ofproject point as well as depths of connected horizons within the OKD (Ostrava-Karviná Collieries), the Institute of Geodesy and MineSurveying developed a new plummet swing observation method during projecting the points into underground by means of a speciallyadjusted plummet.
