Problems solved by technology

The current devices for controlling the infiltration line of the dam body include: 1. A shaft is arranged vertically on the dam surface, and a drainage pump is installed in the well. The groundwater around the shaft penetrates into the well, and the water in the well is discharged by the water pump. The disadvantages are that the precipitation area is small, the efficiency is low, and drainage requires power. , the operating cost is high, especially when the terrain is complex, the water in the well is difficult to discharge; 2. The well is drilled inclined to the dam surface, the aqueduct is placed in it, and seepage holes are evenly arranged around the aqueduct, and the aqueduct is covered with geotextiles to allow groundwater to permeate The geotextile is infiltrated into the pipe, the water guide pipe is connected with the vacuum pump, and the water in the pipe is discharged by the vacuum pump. The disadvantage is that the precipitation area is small, the efficiency is low, and the use of the vacuum pump absorbs water and consumes energy, and the operating cost is high; after a period of operation, the seepage hole is easy to block

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the embodiments.

[0017] Depend on Figures 1 to 4 It can be seen that the self-flowing drainage device of the dam body of the tailings pond includes a vertical shaft 1, six vertical shafts are arranged along the stepped dam surface of the dam body, and a water filter pipe 2 with seepage holes is arranged around the vertical shafts, and the distance between two adjacent vertical shafts is 60m. The difference in elevation at the bottom of the shafts is 1m. The bottoms of the two shafts are connected by an aqueduct 3 with a slope of 1 / 60. A drain pipe 4 is installed under the end shaft to connect with the overflow pool 5. The overflow pool is provided with an overflow port 5.2 to connect with the open drainage ditch 6.

[0018] Depend on figure 1 It can be seen that the vertical shaft 1 is made of concrete and has a cylindrical shape, and the bottom of the well is filled with concrete to...

Abstract

A tailings pond dam body free draining device belongs to mine tailings ponds and particularly relates to a safety stable control device for a tailings pond dam body. The device is characterized in that at least two vertical shafts are arranged along the stepped dam face of the dam body, water filtering pipes with water seepage holes are arranged on the peripheries of the vertical shafts, the distance between the two adjacent vertical shafts is 50-70 m, the difference between bottom levels of the adjacent vertical shafts is 0.8-1.2 m, the bottoms of the two vertical shafts are connected through a water guide pipe, the slope is 1 / 60-1 / 50, a draining pipe is arranged below the vertical shaft at the tail end and connected with an overflowing pond, and an overflowing port is arranged in the overflowing pond to be connected with an open drain. The draining device has the advantages of being wide in application, high in adaptability, especially suitable for rainfall on complex terrain, greatly increasing the rainfall range, being high in rainfall efficiency, ensuring safety and stability of the tailings pond dam body and being stable in structure, sturdy and durable, long in service life and low in maintenance cost. The vertical shafts are connected in series, seepage water flows freely from top to bottom, no power consumption is required for rainfall, the energy is saved, the consumption is reduced, and the operation cost is low. The tailings pond dam body free draining device is favorable for mine safety production and avoids disasters caused by dam body collapse.

Description

technical field [0001] The invention belongs to mine tailing ponds, in particular to a safety and stability control device for tailing pond dams. Background technique [0002] Tailings pond is an important facility for mine production, and the safety and stability of the tailings pond dam directly affects production and endangers the personal and property safety of downstream residents. The infiltration line is one of the important control index parameters for the safety and stability of the tailings pond dam body. According to the design requirements, if the infiltration line is greater than 6m, the dam body is in a safe and stable state. Due to the influence of factors such as site selection for the initial construction of the tailings pond and later dam construction, it is easy to cause the local infiltration line of the dam body to be less than 6m, which endangers the safety of the dam body. Heavy casualties, so the control of the dam body seepage line is very cautious....
