Embodiment 2

[0048] (1) Layout of working base point and displacement observation point

[0049] ① Working base point

[0050] The purpose of embedding the working base point is to facilitate the observation of each displacement observation point. The selected point should be in a relatively stable place with good visibility conditions, and two points should be buried for mutual checking; the coordinate results of the working base point are in the mine Based on the control network, it is measured by making a lower-level displacement monitoring network;

[0051] ②Displacement observation point

[0052] The displacement observation point is buried in a position that can reflect the deformation characteristics, and at the same time, along the initial dam crest, dam foot and downstream of the tailings pond, a total of 5 sections are set, and the distance between each section is 50 meters;

[0053] Others are the same as above.

Embodiment 3

[0055] (1) Layout of working base point and displacement observation point

[0056] ① Working base point

[0057] The purpose of embedding the working base point is to facilitate the observation of each displacement observation point. The selected point should be in a relatively stable place with good visibility conditions, and 8 points should be buried for mutual checking; the coordinate results of the working base point are in the mine Based on the control network, it is measured by making a lower-level displacement monitoring network;

[0058] ②Displacement observation point

[0059] The displacement observation point is buried in a position that can reflect the deformation characteristics, and at the same time, it is set at 7 sections along the initial dam crest, dam foot and downstream of the tailings pond, and the distance between each section is 120 meters;

[0060] Others are the same as above.

Abstract

A method for monitoring movement of a dam body of a five-level tailings pond is characterized by comprising the following contents of: (1) arrangement of a working base point and a movement observation point; (2) a measurement method; (3) office computation; and (4) achievement data. By the technical scheme, angle measuring accuracy and distance measuring accuracy of the method meet technical requirements of a four-level network, and requirements on observation of the movement of the dam body of the five-level tailings pond can be met basically. The method has the advantages that the tailings pond can be monitored by using a simple measuring method, the principle is simple, the method is suitable and easy to operate, and investment cost is low.

Description

technical field [0001] The invention belongs to the technical field of a method for observing the displacement of a five-level mine tailings dam. Background technique [0002] Tailings pond plays a vital role in the safe production of ilmenite mines, and it is related to the survival of enterprises and mines. For the tailings produced by the mine with a concentration of less than 20%, after deposition, the dam is artificially piled up, which may produce varying degrees of deformation within a period of time, resulting in unsafe tailings ponds. Therefore, the monitoring of tailings ponds is conducive to grasping the operation status and safety status of tailings ponds in time, can improve the safety of tailings ponds, and is the eyes and ears of tailings pond safety management. The fifth grade tailings pool is affected by the following three aspects: one is the limitation of topographical conditions, such as the inability to arrange working base points and reference points w...
