Embodiment 1

[0064] In this embodiment, an iron tailings pond in Jiangxi is selected, and the tailings pond is constructed by an upstream filling method. The crest elevation of the initial dam is 205.0m, the crest elevation of the accumulation dam is 229.0m, the final designed dam height is 41.5m, and the minimum safe superelevation is 0.5m. The total storage capacity of the tailings pond is 52.1×10 4 m 3 , the effective storage capacity is 44.29×10 4 m 3 , catchment area is 0.108km 3 . figure 2 The floor plan of each monitoring equipment, image 3 It is the layout diagram of the monitoring equipment for the section of the dam body. According to the length of the dam axis, three monitoring sections of the soaking line and two monitoring sections of the dry beach were selected, and 18 piezometers and 4 laser range finders were installed. In addition, a tipping bucket rain gauge was placed in the open area close to the reservoir area, and a water level gauge was arranged on the drain...

Abstract

The invention provides an online monitoring and comprehensive early warning method for a tailing pond. Real-time monitoring data are obtained online through a rainfall monitoring module, a dry beach monitoring module, a water level monitoring module and a seepage line monitoring module; under the condition of considering various accident risks of the tailings pond, the monitoring data are fully utilized to construct a tailings pond multi-stage comprehensive early warning system; and the obtained real-time monitoring data of the tailings pond is processed, and is compared with a safety parameter threshold value of the tailings pond so as to determine the running condition and the safety early warning level of the tailings pond. According to the method, monitoring data can be effectively utilized, the early warning result is reliable, the feasibility is high, the running state of the tailings pond is reflected from multiple aspects, and reliable technical support is provided for safe running of the tailings pond.

Description

technical field [0001] The invention relates to the technical field of mine safety monitoring, in particular to a method for on-line monitoring and comprehensive early warning of a tailing pond. Background technique [0002] my country is a big mining country, rich in mineral resources, and the reserves of various mineral resources rank among the top in the world. However, the overall characteristics of my country's mineral resources are that there are many lean ores, few rich ores, and generally low metal grades, so there are more solid wastes (ie tailings) formed during the mining and beneficiation process. The tailings contain various chemical reagents and incompletely treated heavy metal components in the beneficiation process. If the tailings are discharged randomly, it will have a serious impact on the ecological environment around the mine and the production and life of residents. Therefore, the construction of tailings ponds by damming the mouth of the valley or enc...
