Embodiment Construction

[0020] In order to further describe the present invention, a method for preventing and controlling water erosion hazards at the junction of mine solid waste dumps and mountains will be further described in detail below in conjunction with the accompanying drawings and examples.

[0021] Depend on figure 1 Shown is a water collection and drainage system layout diagram used in a method of preventing and controlling water erosion hazards at the junction of mine solid waste dumps and mountain bodies in the present invention and combined with figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 It can be seen that the intercepting ditch 2 is built at the junction of the mountain and the solid waste storage yard 6, and the intercepting ditch 2 is built from the uppermost step to the lowermost step of the solid waste storage yard 6 according to the terrain conditions. The intercepting ditch 2 adopts the form of an open channel, Trapezoidal cross-section, the inner walls of th...

Abstract

The invention discloses a prevention and treatment method of water scour hazards of a binding site of a mine solid waste yard and a mountain area. An intercepting ditch (2) is built in the binding site of the mountain area and the solid waste yard (6) and the intercepting ditch (2) is built from the topmost step to the bottommost step of the solid waste yard (6) according to the terrain condition; step drainage ditches (1) are built in each step; the step drainage ditches (1) are communicated with the intercepting ditch (2); sumps (4) are built at the bottommost corners of two ends of the binding site of the mountain area and the solid waste yard (6); the sumps (4) are communicated with a drainage tunnel (3); and a longitudinal bottom of the intercepting ditch (2) is in a step shape. The intercepting ditch (2) is built to communicate with every step drainage ditch (1) to form a multi-stage small area drainage system, so that drainage is drained to the sumps (4) to be guided away from a solid waste accumulation area through the drainage tunnel (3). The prevention and treatment method of the water scour hazards of the binding site of the mine solid waste yard and the mountain area has the advantages of being capable of effectively preventing the binding site of the mountain area and the solid waste yard from water scour, reducing water loss and soil erosion, protecting the environment and preventing landslides and debris flow hazards.

Description

technical field [0001] The invention relates to a method for preventing and controlling water erosion instability in a mine solid waste stockyard, which belongs to the field of mine safety engineering and is applicable to mines where various types of solid waste are piled up. The method can achieve reasonable drainage, prevent erosion, and reduce soil erosion , The purpose of preventing landslides and debris flow disasters, and ensuring the safe operation of mine solid waste stacking. Background technique [0002] Mine infrastructure, mining, mineral processing and other processes generate a large amount of solid waste, mainly including stripped waste rock, mineral processing tailings and heap leaching residue. my country is the world's largest solid waste discharge country. Metallurgical open-pit mines discharge about 2 billion tons of waste rock every year, tailings reserves exceed 10 billion tons, and 800 to 1 billion tons of tailings are added every year. As the scale of...
