6 j’ Complete Specification for the invention entitled: BUNKER FOR SURFACE MINES The following statement is a full description of this invention including the best method of performing it known to us/ma:- 4 c-, ii w j 0 04 0 0 04 0 Q 0 0 bo @00 4 e O

BACKGROUND OF THE INVENTION The present invention relates to a bunker device for receiving and transporting away materials from surface (open pit) mines or similar depositories. The bunker device is of the type that is arranged at a terrace wall forming a loading ramp and includes a bunker provided with a platform and side walls. The bunker devic3 further has an endless conveyor for transporting away the material received by the bunker.
o 0 0 06 In surface mines in which ores, coal or other minerals *10 are mined, and which are often referred to as juarries, the 0 mined or blasted-off material is in most cases intermediately stored in bunkers before it is subjected to further comminuting treatment or classification. The conventional interc Smediate or storage bunkers used for this purpose have stable 15 side walls made of heavy steel structures which must be able to withstand the bulky and often hard material, To be able to charge these bunkers, which is generally performed by 4 heavy-duty trucks or other transporting vehicles and devices, 0 it is known to use the terraced wall formed during mining as the loading ramp to which the bunker is brought closely. If the terraced wall is made of insufficiently solid rock, a special supporting wall must be erected or a special ramp must be provided.

t r- i.M r ih4 -7 -c~ i I1 SUMMARY OF THE INVENTION C Cr C C CCC r It is an object of the invention to provide a bunker system of the above-mentioned type which is of simpler and less expensive construction than loading bunkers according to the prior art.
This object and others to become apparent as the specification progresses, are accomplished by the invention, according to which, briefly stated, a bunker system is provided for accommodating and further transporting materials from surface mines. The system includes a bunker device comprising a platform including an endless conveyor for transporting the material and side walls bounding the platform to form an upwardly open storage area for accommodating the materials. A niche having niche walls is provided in the terrace wall. Some of the side walls form part of the bunker device and are disposed on the platform adjacent the endless conveyor, and some of the side walls are constituted by the niche walls.
The invention further includes a method of producing the novel bunker system.
Due to the fact that some (at least half) of the side walls for the bunker are formed by a niche in the terrace wall, the corresponding side walls which would otherwise have to be provided as part of the bunker are eliminated. Thus a C I Ott

rLO~ C ‘r 3 i: L1
I
U,

13 084/88 r considerable amount of wear is eliminated and the weight of the bunker is significantly reduced. The savings in weight facilitate relocation of the bunker device.
The niche in the terrace wall may already exist in the surface mine or may be specially produced. In the latter event, particularly in the case of a terrace wall composed of harder rock, the niche may be obtained by a blasting process.
If the material of the terrace wall does not have sufficient strength to form a loading ramp, the walls of the niche may 1 fortified in a suitable manner, for example, by supported covers, rammed structures or ground reinforcements. The I anner of fortification depends on the respective conditions and requirements.
So. The slope angle of the bunker side walls formed by the ,niche with respect to the horizontal should not be less than the natural slope angle of the material to be charged. In S case the natural slope angle is exceeded, the material forms a natural slope on which the additionally charged material is 0.0: able to slide down.
0 0 BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective and partially sectional view of a bunker device according to a preferred embodiment of the invention in an uncharged state. r Figure 2 is a view similar to Figure i, shcwing the bunker device in a charged state.
DESCRIPTION OF THE PREFERRED EMBODIMENT Turning now to Figure i, a bunker 2 is disposed in a niche 1, of which only one half is shown. The bunker is supported by thD bottom of the niche. The part of niche 1 not illustrated continues symmetrically on the other side of S bunker 2. Bunker 2 includes a platform 3 which has a I horizontal portion 4 and a portion 6 which ascends toward the *t 0* lD opening 5 of niche 1. Platform 3, in the region of niche 1, is provided with vertical protective walls 7 which extend toward the ground and give the bunker 2 the shape of a downwardly open housing. An endless platform conveyor 8 is disposed in the housing, as can be seen through the brokenaway portion A. The platform conveyor 8 is disposed directly below platform 3, covering a slot 9 extending in the ascending portion 6 and projecting into the horizontal portion 4 of 6404*6 S platform 3. Platform conveyor 8 and slot 9 are disposed centrally relative to bunker 2 and niche 1 and form part of the vertical plane of symmetry of the entire bunker.
Side walls 10 are arranged on both sides of bunker 2, with respect. to its plane of symmetry, and project laterally in the manner of wings beyond vertical protective walls 7.
1 ‘jl
A:
-7 I; i- ;i I r r iri r r rt c t t r P Side walls 10 completely fill the opening 5 of niche 1 with their correspondingly sloped outer edge 11. To adapt themselves to different dimensions of opening 5 and to different slope angles, side walls 10 may be made adjustable in various ways.
In the conveying direction of platform conveyor 8, side walls 10 change to guide walls 12 which laterally delimit platform conveyor 8 outside of niche 1 and outside of bunker 2, where the platform conveyor 8 continues to steadily ascend 10 until it reaches its discharge end (not shown). The discharge end may be provided with a supporting structure 13 connected with bunker 2, particularly if the ascending portion of the conveying path has a substantial length.
In a top plan view, platform 3 has the shape of a nearly regular octagon. The base surface of niche 1 has approximately the same shape as the platform 3 and becomes steadily wider from the base surface toward the top of the 4# niche. The space formed between the vertical side walls 7 S and the side walls of niche 1 due to the widening of niche 1, is filled with a gravel-like material 14 as shown in Figure I. This will prevent protective walls 7 from adhering to the niche in case fine material cakes on the larger contact areas. Protective walls 7 and side walls 10 also prevent the material from reaching the area below platform 3 so that the .4 4 ct44
‘I
6 1- T r .i pe 0a 0 o 0o 0*a *00 *d 0 interior of the housing of bunker 2 is protected. This housing also accommodates the reversing guide and support for platform conveyor 8 and may also receive other required assemblies which are accessible for operation and maintenance from outside of niche 1.
The transportable portion of the bunker device may be moved in a simple manner in that a transporting vehicle provided with lifting devices, for example a transporting caterpillar, enters into a portal-like opening disposed in 10 the region of the center of gravity of the bunker device.
The portal-like opening may be formed, for example, *in the supporting structure 13 between bunker 2 and the supporting structure of the discharge end of platform conveyor 8 as indicated by numeral 15 in Figure 2.
The configuration of the niche is not bound by any defined shape of the terrace wall. The terrace wall may be straight, curved, form a projection or a recess. Also, the niche may be dimensioned in such a way that, if high load performance is required, two or more bunkers can be arranged next to one another in the niche. Moreover, a bunker may also be equipped with a plurality of platform conveyors or other suitable continuous conveyors.
