Description
Technical Field
The invention belongs to the technical field of safety control of tailing ponds and phosphogypsum ponds, and particularly relates to a method for reducing a saturation line of a tailing pond or a phosphogypsum pond.
Background
The infiltration line of the tailing pond and the phosphogypsum pond is the intersection line of a free water surface and the cross section of a dam body formed by the water permeating from the upstream side of the earth dam (or an earth dike) to the downstream side through the dam body, and the height of the infiltration line directly influences the safety and the stability of the tailing pond. The height of a saturation line of a tailing dam or a phosphogypsum dam is directly related to the stability of the tailing dam or the phosphogypsum dam, and a rock block seepage drainage arris body is arranged at the dam foot of the initial dam in the common design. The initial dam is a watertight dam, although the rock block seepage drainage arris body is arranged on the initial dam, the seepage drainage effect cannot reach the expected effect, so a seepage drainage layer is adhered to the inner slope of the watertight initial dam during design, and the pervious layer is communicated with the pervious layer at the bottom of the initial dam. Practice proves that the effect is not ideal when a seepage drainage layer is adhered to the inner slope of the impervious initial dam, and the seepage line of a tailing dam or a phosphogypsum dam is still higher.
The common methods for reducing the saturation line of the tailing dam or the phosphogypsum dam comprise horizontal drainage and seepage, vertical drainage and seepage, combined drainage and seepage of a vertical shaft and a horizontal drainage and seepage pipe, well point drainage and seepage, drainage and seepage of a radiation well and the like. Wherein: arranging a drainage body in the range of a dam foundation or pre-burying drainage bodies such as drainage mats, blind ditches, filter pipes or filter plates and the like on the deposition beach surfaces of tailings (phosphogypsum) at different elevations in horizontal drainage, leading the seepage to a main water collecting pipe and automatically draining the seepage out of the dam; the vertical drainage is to preset or supplement a water seepage vertical shaft on a tailing sedimentation beach in the range of a dam foundation, and water seeped into the shaft is pumped by a machine or is drained out of the dam by self-flowing of a horizontal pipe additionally arranged at the bottom of the shaft. The ' tailing pond infiltration line reduction technical research ' published in the 1O phase of 2009 in Western exploration engineering ' is introduced by adopting a vertical and horizontal combined seepage drainage system, wherein the system consists of a vertical seepage collection well and a horizontal seepage drainage pipe, the vertical seepage collection well penetrates through each layer of saturated tailings, saturated water in each layer of tailings horizontally penetrates into the seepage collection well and is discharged out of a dam body through the horizontal seepage drainage pipe, and therefore the aims of reducing the infiltration line of the dam body and ensuring the stability of the dam body are achieved.
The ' preset drainage and seepage system disclosed in the modern mining industry ' 2015, 2.2.3 reduces a certain tailing pond infiltration line ', the preset drainage and seepage system is automatically developed by combining the engineering situation of tailing pond infiltration line treatment in recent years, the vertical drainage and seepage system is constructed to form three-dimensional drainage and seepage with the original blind ditch conduit, the drainage and seepage water is guided to be discharged from the blind ditch, the vertical drainage and seepage capability of the tailing pond is effectively improved, the tailing pond infiltration line is reduced, and the safe and stable operation of the tailing pond is ensured.
When the particle size of the tailings is thicker, the permeability coefficient of the sedimentary beach of the tailings dam is generally not less than 10-4cm/s, the seepage drainage facility can easily receive obvious effects. The average permeability coefficient in the body of the fine-grain tailing accumulation dam is 10-5～10-6About cm/s, the effect of adopting a common seepage drainage precipitation facility is not obvious, and the clogging is easy to generate particularly in the later period.
