Abstract
A kind of recovery method of Pb-Zn deposits and its purposes of barren rock are invented, recovery method is using strip mining transformation, including establishes tank；Open up working face；The guide rail of cutting machine is set；Cutting machine is installed on guide rail, and cutting exploitation is carried out to ore；Field monitoring is carried out to the ore of extraction, screening is divided into ore, barren rock is stacked respectively；Until ore has been adopted completely.The purposes of barren rock, including be used for making sandstone, further include for processing plank.The width of this method working face, length are unrestricted, and mining depth can reach has adopted ore completely, is not only suitable for new mine, is also applied for the old mine exploited but ore has not been adopted also.Due to carrying out field monitoring, screening to the ore of extraction, classification is stacked, and avoids barren rock from entering processing program, and cutting machine saw-piece is cooled down by water, and waste water recycles, therefore is a kind of pollution-free, zero defects, the recovery method not resulted in waste of resources.Refinery can also will be selected to be placed near mining point, to save the area.Barren rock is also adequately applied obtained by this method.
Description
Technical field
The present invention relates to a kind of recovery method and its purposes of barren rock, the recovery method of especially a kind of Pb-Zn deposits and its useless
The purposes of stone.
Background technology
Currently, exploitation Pb-Zn deposits are essentially all to take mine development end, the method for explosive blasting mine.Since mine is not
Outdoor, and space is limited, when mining, will produce air, contaminated wastewater, and worker can suffer from occupational disease（Silicosis）.Because using more
Level is exploited, and is frequently drilled, explosion, is easy to happen the accidents such as avalanche, permeable.Simultaneously mineral ore deeply using explosion promote by
Limitation, ore can not have been adopted, resulted in waste of resources completely.Have again using blasting mining, mine, ore dressing are surveyed without condition, can only incite somebody to action
Quarried head（Including barren rock）Whole Yun Qu ore dressings area increases expense.The ore fraction of explosive blasting is excessive, and is not bulk,
It is existing select factory will Large Crusher it is broken, wear into pulpous state through ball mill, be transported to ore dressing pond medicine adding, through refining lead zinc
It separates.Remaining waste residue and waste water are sent to fixed location through pipeline and stack in pond, and expropriation of land is put as scrap heap again after piling with
, occupied ground is more.
Invention content
The purpose of the present invention is that invention one kind is pollution-free, zero defects, does not result in waste of resources, is used in combination exploitation field as useless
Material heap puts field, and the purposes of the recovery methods of Pb-Zn deposits and its barren rock that barren rock can be applied fully.
The recovery method of Pb-Zn deposits of the present invention, using strip mining transformation, it is characterised in that include the following steps：It is high in exploitation point
Place and lower establish tank respectively；Open up the working face for installing cutting machine；The guide rail of cutting machine is set；It is installed on guide rail
Cutting machine carries out cutting exploitation to ore；Field monitoring is carried out to the ore of extraction, screening is divided into ore, barren rock difference heap
It puts；It repeats the above steps until ore has been adopted completely.
The purposes of gained barren rock, including it is used for making sand, stone, it is characterised in that further include for processing plank.
This method is using strip mining transformation, and the width of working face, length are unrestricted, and mining depth can reach has adopted completely
Ore is not only suitable for new mine, is also applied for the old mine exploited but ore has not been adopted also.Due to the ore to extraction into
Row field monitoring, screening, classification are stacked, and avoid barren rock from entering processing program, and cutting machine saw-piece is cooled down by water, waste water
It recycles, therefore is a kind of pollution-free, zero defects, the recovery method not resulted in waste of resources.In the exploitation field of the present invention most
It is suitble to place waste residue, barren rock, waste water and other waste materials, exploit and backfilled a certain number of barren rock material, then by original topsoil
It is backfilling into the surface of exploitation field, exploitation field just is restored to plough by this, and such occupied ground is less.
Due to not carrying out explosion when mining, barren rock will not crack, therefore in addition to that can be used for making sand, stone
Except, bulk can also be used for being processed into plank.
Specific implementation mode
The recovery method of Pb-Zn deposits of the present invention, using strip mining transformation, it is characterised in that include the following steps：It is high in exploitation point
Place and lower establish tank respectively；Open up the working face for installing cutting machine；The guide rail of cutting machine is set；It is installed on guide rail
Cutting machine carries out cutting exploitation to ore；Field monitoring is carried out to the ore of extraction, screening is divided into ore, barren rock difference heap
It puts；It repeats the above steps until ore has been adopted completely.
The purposes of gained barren rock, including it is used for making sand, stone, it is characterised in that further include for processing plank.
Cutting machine needs to be water-cooled saw blade, therefore establishes a tank in the place higher than working face, equally than
A tank is also established in the low place of working face, can the water of low tank be extracted into high tank by water pumper, be made storage
The water in pond can recycle.
Mining is typically operation from high to low, and story first opens up the working face that can reach installation cutting machine, working face
Wider, cutting progress is faster.
The guide rail of cutting machine will be set before exploitation, and guide rail is tuned on one side the height while and is lowed, to make cutting wastewater
Toward the tank stream lower than working face.
Monolithic cutting machine is the major product of producer, since cutting Pb-Zn deposits need biplate and four, can contact producer and make into
Biplate or four cutting machines use.Diamond string bead wire cutting machine is for cutting ore lower curtate, to improve cutting efficiency.To ore
Depth, thickness, the length of cutting have certain requirement：The setting of thickness matches with hook machine size；Depth is according to exploitation needs
Different saw blades is selected, the deep big saw blade of selection is cut, cuts shallow selection small saw blade, bottom surface then needs that diamond bead string rope is selected to cut
Cutting mill can just be cut off；Length is unrestricted when cutting.The exploitation number of plies of working face is unrestricted, and mining depth is also just unrestricted
System, until ore has been adopted completely.
Met quality by being monitored or being estimated the quality of ore with hook machine hook stone of opening a mine using side cutting edge when cutting and wanted
That asks is deposited into ore storage, and do not meet quality requirement is then deposited into hillock.The depth of exploitation is determined by ore quality.
The present invention can will select refinery to build near mining point, and the place that surrounding ore is most concentrated is exactly to select refinery.And
The height of refinery is selected to be suitble to pipeline abandoned mine slag and waste water.Mining has used cutting method, and the ore of gained is block-like
Shape, at the scene just with the crushing of hook machine, impact broken, selecting refinery, there is no need to Large Crushers.
Due to not carrying out explosion when mining, barren rock will not crack, therefore in addition to that can be used for making sand, stone
Except, bulk can also be used for being processed into plank, and barren rock is made fully to be applied.
It completes after mining with barren rock, select the remaining antiquated sand of factory's ore dressing and other soil backfilling working faces, backfill thickness is with energy
Subject to enough kind of crops.It is put into earth's surface as far as possible when the table earthen backfill of original place, farming more advantageous in this way.
