Description

Technical Field

[0001] The present invention relates to mine surveying equipment, and particularly to a mine connection surveying device and a surveying method. Background Art

[0002] Mine connection surveying is to transfer the ground plane coordinate system, azimuth and elevation system of the mining area to the underground, establish an underground construction survey control network, and use it as the starting data for various underground surveying operations. It is a comprehensive surveying operation that enables the same coordinate system to be used above and below the well, including plane connection surveying and elevation connection surveying. Currently, the commonly used connection surveying method is to hang a steel wire above the vertical shaft and simultaneously observe the distance and azimuth angle of the steel wire on the ground and underground with a total station, and measure the elevation by lowering a steel tape below. This method has low stability, cumbersome observation, a long stable time for the steel wire rope, a great impact on underground construction and is not safe. At the same time, for plane connection surveying, a steel wire with a diameter of 1 mm needs to be lowered to the designated adit, and for elevation connection surveying, a long steel tape needs to be lowered to the designated adit. The conventional lowering method is to directly place the steel wire or steel tape on a round log or steel pipe. When placed on a round log, it is extremely laborious to pull up the steel wire and steel tape, often requiring multiple people to take turns pulling up, which is time-consuming, laborious and costly. When lowering a steel tape in a deep well connection survey, due to the large friction between the steel tape and the round log, it is easy to damage the rigid structure of the steel tape. When placed on a steel pipe, the friction of the material will cause the steel wire to break and the surface of the steel tape to be damaged, easily causing safety accidents. Therefore, it is necessary to optimize the structure of this mine connection surveying device to overcome the above defects. Summary of the Invention
