Background technology
The most of surface mine of China has entered middle and later periods exploitation, proceeds to deep gradually by superficial part, enters after deep mining, and automobile haul distance lengthens, and conevying efficiency reduces, and transportation cost increases, and causes production cost sharply to rise, and economic benefit glides rapidly.And adhesive tape conveyor has become the main transportation equipment of the one of glory-hole, the combined haulage system of it and automobile composition has become deep open pit transportation system preferably economically technically, this combined haulage system had both been brought into play the dirigibility of Automobile Transportation, the fireballing advantage of pick ditch, has also brought into play the advantages such as adhesive tape transportation cost is low, efficiency is high, automaticity is high, simple and convenient management.But ore deposit automobile transportation system turns automobile-tape transport system and is connected this respect in the open, and domestic surface mine design all lacks overall planning, specifically carry out tape system layout in exploitation during to what degree of depth, there is no clear and definite method.Most of mine is in earlier stage all to adopt single automobile transportation system, it is the increase along with mining depth, motor transport cost increases suddenly, economical obvious when unreasonable, just start to consider to adopt the transport of automobile-adhesive tape, so probably miss the best cohesive position of construction automobile-tape system, do not made mine maximizing the benefits.
Summary of the invention
Object of the present invention is exactly in the above-mentioned defect of determining that automobile transportation system exists while turning automobile-tape transport system cohesive position for domestic surface mine, a kind of definite method that provides surface mine Automobile Transportation to turn automobile-adhesive tape transport cohesive position, makes mine transport reasonable more economically by the cohesive position of the method calculative determination.
(1)build the mathematical model of Automobile Transportation total cost, automobile-adhesive tape transport total cost
The product of the Automobile Transportation total cost unit of equaling Automobile Transportation total cost and mine automobile weighting transportation range; Automobile-adhesive tape transport assembly one's duty two parts, a part is adhesive tape transport total cost, the product of the unit's of equaling adhesive tape transportation cost and adhesive tape weighting transportation range, another part is Automobile Transportation total cost, and the unit's of equaling Automobile Transportation total cost and workplace are to the product of the automobile weighting transportation range of Crushing Station discharge port.The concrete pattern of each transportation cost is as follows:
Motor transport cost:
Automobile-adhesive tape transportation cost:
In formula:
c vapour ---Automobile Transportation total cost, unit;
c
glue
---adhesive tape transport total cost, unit;
h---mining depth, rice;
a

---automobile weighting transportation range, the function relevant to mining depth H, kilometer;
l
glue
---adhesive tape weighting transportation range, the function relevant to mining depth H, kilometer;
l '---
workplace is to the automobile weighting transportation range of Crushing Station, kilometer;
When single Automobile Transportation, weighting transportation range
l vapour one and mining depth
hrelevant function: along with the decline of working bench, automobile weighting transportation range increases gradually,
l vapour can regard one and mining depth as
hbecome approximate direct proportion function:
;
When the transport of automobile-adhesive tape, have two transportation ranges, one is adhesive tape weighting transportation range
l glue, another is the automobile weighting transportation range of workplace to Crushing Station discharge port
l '.
Adhesive tape weighting transportation range
l glue be divided into two parts, a part is adhesive tape horizontal weighting transportation range
, a part is adhesive tape inclination weighting transportation range
; ?
.Wherein adhesive tape horizontal weighting transportation range
with mining depth
hirrelevant, regard constant as; Adhesive tape inclination weighting transportation range
not only with mining depth
hrelevant, simultaneously also relevant with the angle of sealing-tape machine transport:
,
for adhesive tape transport angle, surface mine adhesive tape transport angle is generally less than 20 °.
Workplace is to the automobile weighting transportation range of Crushing Station discharge port
l 'also be divided into two sections:
1. automobile from stope workplace transports to the weighting transportation range of step porch, Crushing Station discharge port place
l 1 .The mining depth of supposing the setting of Crushing Station discharge port is
h i , when mining depth extremely
htime (
h>H i ),
2. step porch, Crushing Station discharge port place is to Crushing Station weighting transportation range
l 2 , can regard constant as.
Therefore
.When the degree of depth of arranging when mining depth and Crushing Station is identical, workplace is to the Automobile Transportation distance of Crushing Station
l '=L 2 .
(2), according to the cost of two kinds of means of transportation and mining depth relation, determine that Automobile Transportation turns the best cohesive position of automobile-adhesive tape transport
The feature of Automobile Transportation is flexibly, invests littlely, and pick ditch speed is fast, but unit cost is high; The feature of adhesive tape transport is that unit cost is low, but investment is large, transports dumb.First opencast mining means of transportation often considers Automobile Transportation, but along with the increase of mining depth, haul distance increases thereupon, and Automobile Transportation total cost will sharply rise.The total cost of adhesive tape transport is also relevant with mining depth, adhesive tape transport start position is arranged darker, transportation cost is also higher, but because adhesive tape unit cost is much smaller than automobile unit cost, the speed that the speed that therefore adhesive tape transport total cost increases with the deepening of exploitation increases much smaller than Automobile Transportation total cost.When strip mining transformation drops to a certain degree of depth
h i time, Automobile Transportation total cost is transported total cost with automobile-adhesive tape and is equated, and mining depth is now the degree of depth that mine Automobile Transportation turns the best cohesive position of automobile-adhesive tape transport.Can extrapolate by the mathematical model in first step:
(3)judge that can automobile turn cost-saving after the transport of automobile-adhesive tape and regain tape transport system construction investment
Determine that Automobile Transportation turns after the mining depth that automobile-adhesive tape transports best cohesive position, also must judge before Mine closure, automobile-adhesive tape transport cost-saving the investment that can regain tape transport system of the accumulation of relatively former single Automobile Transportation in the follow-up developments of mine, if accumulate the cost-saving tape transport system investment that is greater than, to turn the transport of automobile-adhesive tape be that reasonably the cohesive position of being determined by second step is best cohesive position to single Automobile Transportation.Otherwise mine construction tape transport system does not have economic benefit, the concrete pattern of this relation is as follows:
In formula:
h 0 ---mining depth when Mine closure, rice;
h
i
---mining depth when mine turns adhesive tape, rice;
l 2 ---step porch, Crushing Station discharge port place is to the weighting transportation range of Crushing Station, kilometer
;
---adhesive tape horizontal weighting transportation range, kilometer
;
---adhesive tape transport angle, degree;
---adhesive tape investment, unit;
k---be greater than 1 constant.
All the other symbols are identical with step 1.
By above three steps, the present invention has not only determined surface mine automobile and has turned the mining depth of the best cohesive position of automobile-tape transport system, and the economic rationality that simultaneously also can turn the transport of automobile-adhesive tape to mine Automobile Transportation is verified.The optimum economic benefit that transportation system's cohesive position that method draws thus can make mine obtain.
