Description
Technical field
The present invention relates to a kind of surface mine transportation resources, more particularly to surface mine turns vapour by single Automobile Transportation
The intermodal method of car-adhesive tape.
Background technology
China's major part surface mine has had been enter into middle and later periods exploitation, gradually deep is transferred to by superficial part, into deep mining
Afterwards, automobile haul distance is lengthened, conevying efficiency reduction, and cost of transportation increase causes production cost to steeply rise, under economic benefit is rapid
It is sliding.And adhesive tape conveyor has turned into a kind of prevailing traffic equipment of glory-hole, the combined haulage system that it is constituted with automobile
Deep open pit technically economically preferably transportation system is turned into, this combined haulage system has both played Automobile Transportation
Flexibility, dig the fireballing advantage of ditch, also played that low Belt transport cost, efficiency high, automaticity be high, management is easy
The advantages of.But turn automobile-tape transport system linking this respect in Open-Pit Truck Transportation system, domestic design of open pit mines all lacks
Weary overall planning, specifically carries out tape system arrangement, without clear and definite method in exploitation to what depth.Before most of mine
Phase is all to use single automobile transportation system, and simply with the increase of mining depth, motor transport cost abruptly increase, economy is obvious not
When rationally, just start to be considered as automobile-Belt transport, be so likely to have had already passed by construction automobile-tape system optimal
Cohesive position, does not make mine maximizing the benefits.
The content of the invention
The purpose of the present invention is aiming at domestic opencut it is determined that automobile transportation system turns automobile-tape transport system rank
Connecing the drawbacks described above that exists during position, there is provided the determination that a kind of surface mine Automobile Transportation turns automobile-Belt transport cohesive position
Method, calculating the cohesive position determined by this method makes Mine haul more economically reasonable.
(1) Automobile Transportation totle drilling cost, the mathematical modeling of automobile-Belt transport totle drilling cost are built
Automobile Transportation totle drilling cost is equal to the product that unit Automobile Transportation totle drilling cost weights transportation range with mine automobile；Vapour
The well-behaved two parts of car-Belt transport assembly, a part is Belt transport totle drilling cost, is added equal to unit Belt transport cost and adhesive tape
The product of transportation range is weighed, another part is Automobile Transportation totle drilling cost, equal to unit Automobile Transportation totle drilling cost and working face to broken
The automobile of broken station discharge port weights the product of transportation range.The specific pattern of each cost of transportation is as follows：
Motor transport cost：CVapour=LVapour×AVapour
Automobile-Belt transport cost：CVapour-glue=LGlue×AGlue+L′×AVapour
In formula：CVapour--- Automobile Transportation totle drilling cost, member；
CGlue--- Belt transport totle drilling cost, member；
H --- mining depth, rice；
AVapour--- unit Automobile Transportation totle drilling cost, yuan/ton kilometer；
AGlue--- unit Belt transport totle drilling cost, yuan/ton kilometer；
LVapour--- automobile weights transportation range, the function related to mining depth H, kilometer；
LGlue--- adhesive tape weights transportation range, the function related to mining depth H, kilometer；
L ' --- working face to the automobile of Crushing Station weights transportation range, kilometer；
During single Automobile Transportation, transportation range L is weightedVapourIt is a function related to mining depth H：With working bench
Decline, automobile weighting transportation range gradually increase, LVapourOne can be regarded as with mining depth H into approximate direct proportion function：LVapour
=f (H)=kH (k ＞ 1)；
During automobile-Belt transport, there are two transportation ranges, one is adhesive tape weighting transportation range LGlue, another is work
Make face to the automobile weighting transportation range L ' of Crushing Station discharge port.
Adhesive tape weighting transportation range LGlueIt is divided into two parts, a part is adhesive tape horizontal weighting transportation range LGlue is put down, a part
It is that adhesive tape tilts weighting transportation range LGlue is tilted；That is LGlue=LGlue is put down+LGlue is tilted.Wherein adhesive tape horizontal weighting transportation range LGlue is put downWith exploitation
Depth H is unrelated, regards constant as；Adhesive tape tilts weighting transportation range LGlue is tiltedIt is not only related to mining depth H, while going back and sealing-tape machine
The angle of transport is relevant：θ is Belt transport angle, and opencut Belt transport angle is generally less than
20°。
The automobile weighting transportation range L ' of working face to Crushing Station discharge port is also divided into two sections：
1. to the weighting transportation range L of step porch where Crushing Station discharge port after automobile is transported from Stope face1。
Assuming that the mining depth that Crushing Station discharge port is set is Hi, (the H when mining depth is to H>Hi),L1=f (H-Hi)=k (H-Hi),
(k ＞ 1)
2. step porch where Crushing Station discharge port to Crushing Station weights transportation range L2, constant can be regarded as.
Therefore L '=L1+L2=k (H-Hi)+L2, k ＞ 1.When mining depth is identical with the depth that Crushing Station is arranged, working face
Automobile Transportation to Crushing Station is apart from L '=L2。
(2) according to the cost of two kinds of means of transportation and mining depth relation, determine that Automobile Transportation turns automobile-Belt transport
Optimal cohesive position
The characteristics of Automobile Transportation is flexible, invests small, and pick ditch speed is fast, but unit cost is high；The spy of Belt transport
Point is that unit cost is low, but investment is big, is transported dumb.Opencast mining means of transportation often considers automobile fortune first
It is defeated, but with the increase of mining depth, haul distance increases therewith, and Automobile Transportation totle drilling cost will steeply rise.The assembly of Belt transport
This is also relevant with mining depth, and Belt transport start position arrangement is deeper, and cost of transportation is also higher, but due to adhesive tape unit transport
Cost is much smaller than automobile unit cost, therefore the speed that Belt transport totle drilling cost increases with the deepening of exploitation is much smaller than vapour
The speed that car transport totle drilling cost increases.When strip mining transformation drops to a certain depth HiWhen, Automobile Transportation totle drilling cost and automobile-adhesive tape
Transport that totle drilling cost is equal, mining depth now turns the depth of the optimal cohesive position of automobile-Belt transport for mine Automobile Transportation
Degree.It can be extrapolated by the mathematical modeling in first step：
(3) judge that can automobile turn cost-effective after automobile-Belt transport and withdraw tape transport system construction investment
Determine after the mining depth that Automobile Transportation turns the optimal cohesive position of automobile-Belt transport, it is necessary to judge in mine
Close before hole, can the accumulation of automobile-Belt transport relatively former single Automobile Transportation in the follow-up developments of mine is cost-effective to receive
The investment of tape transport system is returned, if accumulation is cost-effective to be more than tape transport system investment, single Automobile Transportation turns vapour
Car-Belt transport is the i.e. optimal cohesive position of cohesive position that is rational, being determined by second step.Otherwise, mine construction adhesive tape
Transportation system does not have economic benefit, and the specific pattern of the relation is as follows：
In formula：H0--- mining depth during Mine closure, rice；
Hi--- mine turns mining depth during adhesive tape, rice；
L2--- step porch where Crushing Station discharge port to the weighting transportation range of Crushing Station, kilometer；
LGlue is put down--- adhesive tape horizontal weighting transportation range, kilometer；
θ --- Belt transport angle, degree；
P --- adhesive tape is invested, member；
K --- the constant more than 1.
Remaining symbol is identical with step one.
By three above step, the present invention not only defines surface mine automobile and turns automobile-tape transport system
The mining depth of optimal cohesive position, while the economic rationality that can also turn automobile-Belt transport to mine Automobile Transportation is carried out
Checking.Thus transportation system's cohesive position that method is drawn can make the optimal economic benefit that mine is obtained.
Brief description of the drawings
Fig. 1 is that surface mine Automobile Transportation of the present invention turns the dew that the determination method of automobile-Belt transport cohesive position is calculated
Its mine automobile turns the optimal cohesive position schematic diagram of automobile-tape transport system.
Embodiment
Automobile-Belt transport cohesive position is turned to surface mine Automobile Transportation of the present invention with reference to the accompanying drawings and examples
The method of determination is described in further detail.
In surface mine actual production, during using single Automobile Transportation, with the increase of mining depth, haul distance increases therewith
Plus, transportation route LVapourIt is divided into two sections, one section is step entrance weighting transportation range where Stope face to Crushing Station discharge port
L1, one section is weighting transportation range L of the step entrance where Crushing Station discharge port to stockyard3；During automobile-Belt transport, supply line
Road is divided into three sections, and first paragraph is the weighting fortune to step porch where Crushing Station discharge port after automobile is transported from Stope face
It is defeated apart from L1, second segment is that step porch where Crushing Station discharge port to Crushing Station discharge port weights transportation range L2, the 3rd section
It is adhesive tape weighting transportation range LGlue。
Surface mine Automobile Transportation of the present invention as shown in Figure 1 turns the determination method meter of automobile-Belt transport cohesive position
The surface mine automobile of calculation turns the optimal cohesive position schematic diagram of automobile-tape transport system.
Single motor transport cost is C with the functional relation of mining depthVapour=AVapourKH, automobile-Belt transport cost with
The functional relation of mining depth is CVapour-glue=AVapourk(H-Hi)+AVapourL2+AGlueLGlue is put down+AGlueHi/ tg θ, from figure 1 it appears that with
The increase of mining depth, the cost of automobile-Belt transport is far above using the cost growth rate of single Automobile Transportation, works as dew
Its exploitation drops to a certain depth HiWhen, function and automobile-Belt transport that single motor transport cost changes with mining depth
When the function that cost changes with mining depth intersects, now Automobile Transportation totle drilling cost is equal with automobile-Belt transport totle drilling cost, right
The mining depth H answerediTurn the optimal linking mining depth of automobile-Belt transport for Automobile Transportation.If in HiOn turn adhesive tape fortune
Defeated, Belt transport cost is higher than motor transport cost within a period of time, although as the extension of mining depth, subsequent tapes fortune
Defeated cost advantage will gradually embody, and cost is lost before can making up, but does not make the whole maximization of economic benefit in mine.Such as
Fruit is in HiUnder Hi' turn Belt transport again, then in Hi~Hi' between be still use Automobile Transportation, automobile in this section of interval
The cost of transport is more than automobile-Belt transport cost, in HiWhen ' place turns Belt transport again, although and single automobile fortune before
It is defeated to save cost of transportation, but actually had already passed by optimal cohesive position, also without maximizing mine economic profit,
If turning the position of Belt transport too late, it is likely that to Mine closure, the cost of transportation of saving can't make up the throwing of adhesive tape
Rate are used, and such tape transport system is just without any economic benefit.Determine that Automobile Transportation turns the optimal rank of automobile-Belt transport
Meet position HiAfterwards, in HiTo final mining depth H0In this interval, the difference of two functions, that is, the closing triangle constituted
Area is that automobile-tape transport system is cost-effective compared to what single automobile transportation system was accumulated, is more than when accumulation is cost-effective
Tape transport system is invested, then it is rational that single Automobile Transportation, which turns automobile-Belt transport,.Otherwise, mine need not turn adhesive tape fortune
Defeated system.
