Description

The synchronous water seepage drainage and reinforcement device of a kind of novel tailing dam
Technical field
The utility model relates to the mine safety device, the synchronous water seepage drainage and reinforcement device of especially a kind of novel tailing dam.
Background technology
China is a mining powers, and mine year discharging mine tailing reaches 600,000,000 tons.Except that fraction as filling in mine or the comprehensive utilization, the overwhelming majority is stored up in the mine tailing storehouse.The mine tailing storehouse is exactly the association that stores the various facilities of mine tailing, also is the necessary facility of keeping the mine ordinary production.
According to statistics, by the end of the year 2008,12655 in total mine tailing storehouse, the whole nation, also increasing newly in the scale with more than 300 every year.Wherein, danger, danger, sick storehouse account for 39% of sum; China be the whole world have mine tailing storehouse quantity at most, mine tailing storehouse accident potential leads one of the highest country.In the various great disaster in the world, mine tailing storehouse disaster is only second to generation earthquake, cholera, flood and hydrogen bomb etc. and occupy the 18th.In a single day it have an accident, and will cause significant damage to area, the downstream people's life and property, and environment is caused severe contamination.Therefore, the security and stability in mine tailing storehouse is very important, and wherein, the safety in mine tailing storehouse depends primarily on the security and stability of tailing dam, and therefore, the safety and stability technology of tailing dam is one of object of mine safety technical field primary study always.
The tailing dam on upper reaches method heap dam is meant material construction initial dam such as adopting soil, stone, then based on initial dam, utilizes mine tailing to pass through evenly ore drawing upwards of waterpower alluviation, the direction rising in the storehouse of one-level one-level ground, and generally angle of dump slope was at 1: 3.5~1: 5.The reason that adopts the tailings pile dam mainly is in order to reduce the cost of tailing dam, not replace earth and rockfill dam if do not adopt the tailings pile dam, and then engineering quantity is great so cost is surprising height.The tailing dam quantity on China upper reaches method heap dam accounts for more than 90% of mine tailing fill dam, is the main flow form of domestic mine tailing fill dam.
The particle that the process form of this uniqueness in upper reaches method heap dam has determined the stability of upstream formula mine tailing fill dam to depend on and deposited dried beach face is formed and the degree of consolidation.For guaranteeing and improve the security and stability of mine tailing fill dam, need to reduce dam seepage line, the acceleration tailings dewatering is fixed, therefore, water seepage drainage facility must be set in tailing dam.Water seepage drainage facility can in time be derived the infiltration in the mine tailing dam body, reduces dam seepage line, and the acceleration mine tailing is fixed, guarantees that tailing dam has the dam shell of enough relatively dries, significantly improves the stability of tailing dam.
The investigation of carrying out according to 2003~2004 years State Administration of Quality and Technical Supervision shows, because what mine tailing fill dam shortage water seepage drainage facility or water seepage drainage facility lost efficacy accounts for tailing dam safety sufferer more than 60%, this shows, strengthen to mine tailing fill dam water seepage drainage facility to reconstruct, eliminate tailing dam accident potential, sufferer extremely urgent.
Many emphasis are carried out in the horizontal direction when at present the tailing dam water seepage drainage facility of having built being reconstructed, and promptly rely on mechanical drilling equipment to make lateral aperture in the mine tailing fill dam, and horizontal drainage pipe is sent in the dam body.This method collects, carries the head difference of infiltration less, so the waterpower influence basin is very limited, so reduce the phreatic line DeGrain, little to tailing dam improved stability dynamics, and arrange that density more just can play the water seepage drainage and reinforcement effect, generally spacing 3~5m arranges one deck on vertical plane, 5~10 meters of every layer of (on the horizontal plane) drain level spacings, thereby cost is higher.The less row who carries out vertical direction is oozed, and oozes floral tube because of tubing adopts plastics row, and caliber is little, and mainly relies on the colored hole on the tube wall to collect infiltration, and seepage area is limited, so collection infiltration effect is not strong.
Summary of the invention
The purpose of this utility model is to provide a kind of novel tailing dam synchronous water seepage drainage and reinforcement device, and this device can be eliminated tailing dam and ooze the bad sufferer that causes because of row, and the acceleration tailings dewatering is fixed, reduces the tailing dam wellability, improves the security and stability of tailing dam.
The technical solution of the utility model is: the synchronous water seepage drainage and reinforcement device of a kind of novel tailing dam, this device comprise the tailing dam on upper reaches method heap dam, and the tailing dam on upper reaches method heap dam comprises the mine tailing fill dam of initial dam and initial dam upside; A group or more continuous sand drain device is set in the mine tailing fill dam, and the sand drain device is perpendicular to mine tailing fill dam bottom surface continuously; Row is oozed floral tube and is connected with continuous sand drain device, also is positioned at the mine tailing fill dam, and perpendicular to mine tailing fill dam transversal line, and pipe end stretches out outside the mine tailing fill dam on horizontal plane.The sand drain device comprises the many groups of row cloth bag sand drain continuously, and the cloth bag sand drain is made of non-woven geotextile parcel sand gravel.Row is oozed floral tube coated outside one deck non-woven geotextile.
Advantage of the present utility model is: it is fixed to quicken tailings dewatering, reduces tailing dam saturation line greatly, significantly improves the security and stability of tailing dam, thereby the tailing dam of eliminating upper reaches method heap dam oozes the bad sufferer that causes because of row.It has overcome the defective of conventional apparatus, collection is oozed, arranges the powerful continuous sand drain device of the ability of oozing to be oozed floral tube with row and combines, tailing dam arranged synchronously ooze, thereby both enlarged the seepage area on the vertical direction and promoted vertical direction infiltration capacity gauge greatly, strengthen horizontal drainage pipe again and carry the ability of infiltration, thereby significantly reduce the tailing dam wellability, the acceleration tailings dewatering is fixed, improves the security and stability of tailing dam greatly.This water seepage drainage and reinforcement device have cost low, save unique advantages such as the energy (infiltration gravity flow under action of gravity), management maintenance is easy, have and promote the use value preferably.
