Abstract

The invention provides a center line calibration method for an underground straight roadway, which comprises the following steps of: selecting any point on a first pre-calibrated center line as a rearview point, and suspending a first vertical calibration structure at the rear view point; selecting any point on a second pre-calibrated center line as an erection point, and suspending a second vertical calibration structure at the erection point; arranging a distance measuring device at the second vertical calibration structure, taking the first vertical calibration structure as a new rear viewpoint, enabling the distance measuring device to be aligned with the first vertical calibration structure, and rotating the distance measuring device by 180 degrees to obtain a new central line orientation; determining a new center line in the direction of the new center line according to the distance between the first vertical calibration structure and the second vertical calibration structure;and calibrating the new center line. The invention can solve the problems that at least two station instruments need to be erected, the measurement process is complicated, the working efficiency is low and the like in the process of carrying out center line calibration on a long-distance linear roadway in the prior art.

Description

technical field [0001] The invention belongs to the technical field of downhole ranging, and more specifically relates to a method for marking the centerline of downhole straight roadways. Background technique [0002] At present, the downhole center line stakeout is usually a group of 30m to 40m, and the points on the center line to be placed are derived from known control points, and then the center line is determined after setting up instruments on the center line points. This method requires at least two stations of instruments. The whole midline calibration process is relatively complicated. If the above-mentioned method is used for long-distance straight roadways, such as the quasi-slope of the piercing roadway of the quasi-acquisition project, it will take a lot of time, the measurement process is complicated, and the work efficiency is low. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a method ...
