AI Technical Summary

Technical Problem

In open-pit coal mining, traditional Beidou monitors have weak signals, which affect the real-time monitoring effect of data. They have high technical requirements and are limited in use, so they cannot effectively monitor the asynchronous displacement of the slope surface and bottom layer.

Method used

A slope displacement monitoring device for open-pit coal mining is designed, including positioning mechanism, connecting rod mechanism, bottom monitoring mechanism, stabilizing mechanism and top-level monitoring mechanism. The bottom monitoring mechanism monitors the displacement of the slope by inserting plates and rotary plates, and the top monitoring mechanism monitors the displacement of the slope by inserting plates, slide rods and rotary rods.

Benefits of technology

Independent and accurate monitoring of the displacement of the slope surface and bottom layer is achieved, avoiding the impact of signal connection on the monitoring effect, and improving the real-time and accuracy of monitoring.

Abstract

The invention relates to the technical field of slope displacement monitoring, in particular to an open pit coal mine mining slope displacement monitoring device which comprises a positioning mechanism, a connecting rod mechanism, a bottom layer monitoring mechanism, a stabilizing mechanism and a top layer monitoring mechanism. The end, away from the round block, of the connecting rod is connected with the positioning mechanism. By arranging the bottom layer monitoring mechanism, the whole insertion plate can be inserted into the ground, displacement change monitoring of the side slope bottom layer is achieved through a rotating plate in the insertion plate, if the side slope bottom layer has a displacement condition, soil can directly extrude the rotating plate to enable the rotating plate to rotate, the displacement amount of the side slope bottom layer can be judged according to the rotation amount, and use is convenient; and the rotating plate is arranged in the insertion plate, and the whole insertion plate cannot move or rotate, so that the influence of the displacement change of the top layer of the slope on the rotating plate can be avoided.
