Description
Technical Field
The invention relates to the technical field of tailing pond monitoring, in particular to a device and a method for online monitoring of a saturation line of a tailing pond by a midline method.
Background
The tailings pond is a place which is formed by damming and intercepting a valley opening or surrounding land and is used for stockpiling metal or nonmetal mines for ore sorting and then discharging tailings (waste sand), and is an essential important facility for mine production. Meanwhile, the tailing pond is an artificial debris flow danger source with high potential energy, the danger of dam break exists, major accidents are easily caused once the mine fails, major personnel and property loss are caused, and major social influence is generated. The dam break hazard of the tailing dam is a main disaster of the tailing pond and is a key monitoring object of the tailing pond. In order to ensure the safe operation of the tailing pond, online monitoring facilities are required to be installed on a dam body and a pond area of the tailing pond, wherein a dam body infiltration line is an important safety index of the tailing dam, and the online monitoring of the dam body infiltration line is an important component of an online monitoring system of the whole tailing pond.
The damming mode of the tailing pond is divided into one-time damming, upstream damming, middle line damming, downstream damming and the like. At present, the tailing pond mainly adopts an upstream method and a midline method, but the installation and the use of an online monitoring device of a saturation line of a tailing dam adopting the midline method have the following problems:
the first problem is that: the tailings dam outer slope constructed by the middle line method dynamically changes along with the damming process, and the infiltration line monitoring equipment fixedly installed on the outer slope can be influenced by damming construction and can be buried by tailings with the constantly rising outer slope surface. At present, a midline method tailing dam monitoring device is lifted along with a dam body in a damming process, in order to avoid burying, a seepage line monitoring device arranged on the surface of the dam body needs to be disassembled, and the seepage line monitoring device is arranged at an original position again after the dam body is piled to a stage elevation; the seepage line monitoring sensor installed inside the dam body is installed in a drill hole, an originally installed monitoring facility needs to be detached from a monitoring hole opening, the sensor installed in the hole is taken out, the monitoring device and the sensor are installed back after the infrastructure on the upper portion of the monitoring hole is heightened, the whole process is time-consuming and labor-consuming, the installation position of the water level sensor in the monitoring hole can be changed in the reinstallation process, the monitoring process is discontinuous, and monitoring data are inaccurate. In short, the problem is the disassembly and assembly process problem of the seepage line monitoring facility of the midline method tailing pond lifted along with the dam body, which is a main reason that the online monitoring of the seepage line of the midline method tailing pond cannot be normally implemented.
The second problem is that: in the middle line method damming process, large engineering machinery is needed for building the outer slope of the dam, and the damage and data interruption of the cable which is collected by the saturation line sensor to the acquisition device or is connected with the upper computer by the acquisition device can be easily caused (for example, the cable between the saturation line sensor and the acquisition device which are buried under the tailings and the cable between the acquisition device and the far-end acquisition computer can be cut by a bulldozer for damming work on the dam surface). The problem is the cross damage problem of monitoring facilities and damming construction, and is one of the reasons that the online monitoring of a wetting line cannot be normally implemented in many tailing ponds adopting a medium-line method.
The third problem is that: the data transmission of the existing online saturation line monitoring system is local area network acquisition, all data are collected to a locally arranged acquisition computer of a tailing pond, the stable operation of the system depends on the maintenance intensity of a local area network, and the failure of any node can cause the local or whole breakdown of the system. This problem seriously affects the overall stability of the on-line monitoring system, both in the upstream tailings ponds and in the middle-line tailings ponds, and is particularly serious in the middle-line tailings ponds.
