Description
Technical field
The present invention relates to the middle part transporting coal ditches in technical field of coal exploitation more particularly to a kind of suspension bucket pinch spalling separating process to move
If the method for determining.
Background technology
Suspension bucket heap stripping technology of slide tackling is a kind of advanced strip mining transformation technique, it collects three digging, transport and casting works
Industry dumps the direct casting of overburden in outdoor internal dumping, in one with number of devices is few, unit bucket capacity is efficient, stripping
From distinguishing features such as at low cost, production capacity is big, production reliability height.Pinpoint blasting technology shovels backcast stripping work for suspension bucket
The overburden of 20%-50% is directly thrown into goaf by skill, so as to further improve charge stripping efficiency, be greatly lowered stripping into
This.
In the construction process, the middle part transporting coal ditch between two production zones is needed to carry out shifting to set, and in how determining
The shifting of portion's transporting coal ditch, which sets distance, becomes technical barrier.
Invention content
The purpose of the present invention is to provide the middle part transporting coal ditch shiftings in kind of suspension bucket pinch spalling separating process to set determining method.
The middle part transporting coal ditch shifting that technical solution of the present invention is provided in a kind of suspension bucket pinch spalling separating process sets determining method, including such as
Lower step：
Step 1：Determine the quantities V that middle part transporting coal ditch shifting is sety；
Step 2：It determines to set quantities V by automobile slidingyThe increased cost C of institute；
Step 3：Determine the economic loss S that middle part transporting coal ditch shifting is setmy；
Step 4：Work as SmyWhen=0, determine that best move of middle part transporting coal ditch sets distance.
Further, following steps are further included in the step 1：
Set the width of middle part transporting coal ditch as D, to retrodict step internal dumping average height be Hxp, Automobile Transportation limitation slope
The shifting of degree i and middle part transporting coal ditch set distance L, then：
Further, following steps are further included in the step 2：
Set the freight ton-km C of Automobile Transportationd, transporting coal amount M of the open coal mine through middle part transporting coal ditchc, then increased transport
Cost C can be calculated by following formula：
Further, following steps are further included in the step 3：Unit price is constructed as q in setting ramp,
Then, Smy=qVy-C。
Further, as economic loss SmyWhen=0, obtain most preferably shifting and set distance：
Further, the width of a secondary pinpoint blasting step is set as K,
Such asAnd N is integer, then final move of middle part transporting coal ditch sets distance LEventually=L；
Such asAnd n.m is not integer, wherein n is integer part, and m is fractional part,
Then LEventually=(n+1) K.
Using above-mentioned technical proposal, have the advantages that：
Quantities, increased cost and the economic damage set by determining middle part transporting coal ditch shifting, come determine most preferably to move set away from
From the shifting setting tool for middle part transporting coal ditch has directive significance.
Description of the drawings
Fig. 1 is the schematic diagram that transporting coal ditch shifting in middle part is set；
Fig. 2 is the flow chart that transporting coal ditch shifting in middle part sets determining method.
Specific embodiment
Specific embodiment to further illustrate the present invention below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, the middle part transporting coal ditch shifting in the suspension bucket pinch spalling separating process that one embodiment of the invention provides sets determining
Method includes the following steps：
Step 1：Determine that middle part transporting coal ditch 1 moves the quantities V sety；
Step 2：It determines to set quantities V by automobile slidingyThe increased cost C of institute；
Step 3：Determine that middle part transporting coal ditch 1 moves the economic loss S setmy；
Step 4：Work as SmyWhen=0, determine that best move of middle part transporting coal ditch 1 sets distance.
Quantities, increased cost and the economic damage set by determining middle part transporting coal ditch shifting, come determine most preferably to move set away from
From economic loss is minimum at this time, and the shifting setting tool for middle part transporting coal ditch has directive significance.
Preferably, further include following steps in the step 1：
Set the width of middle part transporting coal ditch as D, to retrodict step internal dumping average height be Hxp, Automobile Transportation limitation slope
The shifting of degree i and middle part transporting coal ditch set distance L, then：
Middle part transporting coal ditch 1, which is calculated, according to above-mentioned formula moves the quantities V that setsy, to carry out subsequent operation.
Preferably, following steps are further included in step 2：
Set the freight ton-km C of Automobile Transportationd, transporting coal amount M of the open coal mine through middle part transporting coal ditchc, then increased transport
Cost C can be calculated by following formula：
Increased transportation cost C is calculated according to above-mentioned formula, to carry out subsequent operation.
Preferably, following steps are further included in step 3：Unit price is constructed as q in setting ramp,
Then, Smy=qVy-C。
Economic loss S is calculated according to above-mentioned formulamy, to carry out subsequent operation.
Preferably, as economic loss SmyWhen=0, obtain most preferably shifting and set distance：
It that is to say, when approach shift spacing is L, economic loss zero, best results.
Preferably, the width of a secondary pinpoint blasting step is set as K,
Such asAnd N is integer, then final move of middle part transporting coal ditch sets distance LEventually=L；
Such asAnd n.m is not integer, wherein n is integer part, and m is fractional part,
Then LEventually=(n+1) K.
It that is to say, set distance L=240m, K=80m if most preferably moving, then N=3, then LEventually=L=240m.
If best move sets distance L=216m, K=80m, then n.m=2.7, wherein n is integer part 2, LEventuallyIt needs for K
Multiple, so to n.m roundings and add 1, that is, LEventually=(n+1) K=240m.
Through analyzing calculating above, consider engineering development requirement, often promoted three times according to suspension bucket shovel working face, form 3 width and throw
After throwing explosion step, shifting sets primary middle part transporting coal ditch 1.When suspension bucket slide tackles the 3rd width pinpoint blasting step of heap, new middle part is reserved
Ditch longitudinal direction ramp, then form new transporting coal raceway groove after adopting 5 width pinpoint blasting steps.
Assuming that the coal length of bench of open coal mine is S, fltting speed V, then the service time t=S/ of middle part transporting coal ditch 1
V。
As needed, above-mentioned each technical solution can be combined, to reach best-of-breed technology effect.
Above-described is only the principle of the present invention and preferred embodiment.It should be pointed out that the common skill for this field
For art personnel, on the basis of the principle of the invention, several other modifications can also be made, also should be regarded as the protection model of the present invention
It encloses.
