On-line monitoring method of dry beach length of tailing pond

Abstract

The invention discloses an on-line monitoring method of the dry beach length of a tailing pond. The method includes the steps that firstly, a certain number of osmometers are sequentially arranged on a dry beach surface of the tailing pond so as to acquire a real-time seepage line; secondly, after the arrangement position of each measuring point is determined, the three-dimensional coordinates of the position where the measuring point is located are measured; thirdly, a corresponding pond length-dam height coordinate system is established according to the relative position of the dry beach surface and a dam body; fourthly, each measuring point is fitted into the established corresponding system according to the measured three-dimensional coordinates of the measuring point, and the needed dry beach length is worked out. The method can be applied to dry beach surfaces with different shapes, improve the monitoring accuracy of the dry beach length, and reduce the probability of a system to be struck by lightning, thereby improving the lightning protection reliability of the system.

Description

technical field [0001] The invention relates to the technical field of mining and metallurgy, in particular to a method for on-line monitoring of the dry beach length of a tailings pond. Background technique [0002] At present, the dry beach length is an important indicator of the operation of the tailings pond. Its significance lies in controlling the water level of the tailings pond and preventing the danger of dam overflow. Therefore, real-time monitoring of the dry beach length of the tailings pond is an important task for the daily management of the tailings pond. The key issues that must be solved for an accurate dry beach length measurement method are adaptability, accuracy, reliability and cost; due to the different tailings pond dry beach lengths and dry beach surface shapes, the current commonly used various None of the dry beach length measurement methods can be adapted to all dry beach surfaces, and its application has great limitations, and the accuracy and rel...

Problems solved by technology

The disadvantage of this method is that when the dry beach surface is curved and long (thousands of meters), the measurement distance will still be greatly restricted. When the weather conditions are bad, the measurement accuracy of the laser will also be greatly affected, and its The cost is very high, and the same equipment is located on an open dry beach, and the lightning protection capability of the system is weak
