The connecting conveyor belt unit has a head station and a rear station, whereby the head station is divided into a mobile head pulley station (2) and a stationary transfer station (1). A mining-related change in length of the conveyor belt between the rear station (3) and the transfer station (1) is adjusted by a change in length between the mobile head pulley station (2) and the transfer station (1). Belt frames (4) between the head pulley station (2) and the transfer station (1) can be removed and be inserted between the rear station (3) and the transfer station (1). A connecting conveyor belt unit is provided with a head station, which is divided into a mobile head pulley station (2) and a stationary transfer station (1), and a mobile rear station (3), so that mining-related position displacements of the rear station (3) can be compensated by means of identical position displacements of the head pulley station (2).
Description
CONNECTING CONVEYOR BELT UNIT FOR MINING
MATERIALS IN LAYERS IN A STRIP MINE AND PROCESS
FOR ADAPTING THE CONNECTING CONVEYOR BELT UNIT
TO THE MINING PROGRESS
FIELD OF THE INVENTION
[1] The present invention pertains to a connecting conveyor belt unit for the mining of material in layers in a strip mine and a process for its adaptation to the mining progress.
BACKGROUND OF THE INVENTION
MATERIALS IN LAYERS IN A STRIP MINE AND PROCESS
FOR ADAPTING THE CONNECTING CONVEYOR BELT UNIT
TO THE MINING PROGRESS
FIELD OF THE INVENTION
[1] The present invention pertains to a connecting conveyor belt unit for the mining of material in layers in a strip mine and a process for its adaptation to the mining progress.
BACKGROUND OF THE INVENTION
[2] The material in a raw material strip mine is usually mined in many layers with mining heights of 10-15 m.
[3] In small strip mines, the material is mined by means of shovel dredgers and carried and dumped by means of trucks to the processing plant or to the overburden dump. This method is very flexible and also economical because of the short transport distances and low depths.
[4] In larger strip mines, the transport distances and lifting heights increase, so that the necessary number of trucks and the fuel consumption increase sharply. This burdens the environment due to high waste gas emissions and is also uneconomical from a certain size. In larger strip mines, transport by means of trucks is therefore partly or entirely replaced with a belt conveying.
[5] In an entire replacement of the trucks, shovel dredgers, mobile crushers and mobile conveyor belts are used on the mining level. A connecting belt which must always be adapted to the mining progress takes charge of conveying out of the strip mine. The further io conveying on the surface takes place via stationary connecting belts to a raw material dump or the center of rotation of an overburden dump.
[6] The connecting belt is usually bolted to each mining level until the shovel dredgers can reach the strip mine end. Then it is mined again and then bolted anew to the next mining level. This process has the advantage that the head station is simple and completely stationary. On the other hand, the frequent lengthening and shortening of the belt connected therewith is very disadvantageous, since this must thus always be cut again and re-vulcanized.
This is time-consuming, causes losses in belt length and is adverse for the belt strength. This method leads to an increased wear of the conveyor belt.
SUMMARY OF THE INVENTION
This is time-consuming, causes losses in belt length and is adverse for the belt strength. This method leads to an increased wear of the conveyor belt.
SUMMARY OF THE INVENTION
[7] An object of the present invention is to provide a connecting conveyor belt unit and a process for adapting the connecting conveyor belt unit to the mining progress which is simple and is connected with minimal interruption times.
[8] According to the invention, a process is provided for adapting the length of a connecting conveyor belt unit for the mining of material in layers in a strip mine. The connecting conveyor belt unit has a head station and a rear station. The head station is divided into a mobile head pulley station and a stationary transfer station. A mining-related change in length of the conveyor belt between the rear station and the transfer station is compensated by means of a change in length between the mobile head pulley station and the transfer station.
[9] According to another aspect of the invention, a connecting conveyor belt unit is provided for the mining of material in layers in a strip mine. The connecting conveyor belt unit comprises a head station, which is divided into a mobile head pulley station, and a stationary transfer station, and a mobile rear station. Mining-related position displacements of the rear station can be compensated by means of identical position displacements of the head pulley station.
[10] The object is accomplished by the normal stationary head station being divided into a stationary transfer station and a mobile head pulley station. The mobile head pulley station and/or mobile rear station can be displaced or conveyed, for example, by means of a crawler-type chassis, wheels or by mounting on a pontoon. In addition, the mobile stations may have their own drive in the form of an electric motor or internal combustion engine, which makes possible a very fast adaptation. Due to the movement of the head pulley station and rear station, the change in length between the displaceable and conveyable rear station and the stationary transfer station is compensated, so that the belt always maintains the same length. The transfer of the mined material at a downstream conveying means or the removal takes place at the stationary transfer station. Consequently, a downstream conveying means, in case of an adaptation of the head pulley station and rear station, may remain unchanged.
[1 1] In the process for adapting the connecting conveyor belt unit to the mining progress, a connecting conveyor belt unit with a mobile rear station and a head station are used, whereby the head station is divided into a stationary transfer station and a mobile head pulley station. A necessary change in length between the mobile rear station and transfer station is compensated by means of an analogous change in length between the transfer station and the mobile head station; for example, in a deeper setting of the rear station, the head pulley station is also displaced or conveyed by a corresponding distance. Thus, the connecting conveyor belt unit can advantageously be adapted to the mining depth without cutting the conveyor belt.
[12] Belt frames are arranged between the rear station and transfer station and between the transfer station and head pulley station for supporting the conveyor belt.
Preferably, only belt frames between the head pulley station and the transfer station are removed and inserted again between the rear station and the transfer station or vice versa for the adaptation. Thus, the effort for an adaptation process can advantageously be further minimized.
[13] An exemplary embodiment of the present invention is explained below on the basis of two figures. The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which preferred embodiments of the invention are illustrated.
BRIEF DESCRIPTION OF THE DRAWINGS
[14] Figure 1 is a sectional view of the layers of a strip mine;
and [15] Figure 2 is a connecting conveyor belt unit according to the present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[16] Figure 1 shows the various layers of a strip mine, whereby after mining a layer a deeper setting of the connecting conveyor belt unit to the new mining site is necessary. On the side on which the conveyor belt shall be positioned, the slope of the strip mine is 20%. A
connecting conveyor belt unit according to Figure 2 is used in this case.
[17] Figure 2 shows a connecting conveyor belt unit according to the present invention in a side view. For the purpose of improved visibility, the rear station is shown separately in the upper area of the figure. The connecting conveyor belt unit has a stationary transfer station 1, a mobile head pulley station 2 and a mobile rear station 3. The conveyor belt is supported by means of the belt frames 4a and belt frames 4b between the stations.
[ 1 8] The stationary transfer station 1 has a discharger pulley 5 with drives, a second driving pulley 6 with drives, a tail pulley 7 and a tensioning pulley 8. The pulley 9 on the mobile head station 2 and the pulley on the mobile rear station 3 have no drives. The material discharged at the head pulley 5 is further conveyed by the conveyor belt unit 11 arranged under the head pulley 5.
[19] When lengthening the connecting belt, the rear station 3 and head pulley station 2 move backwards at the same time. During this process, the belt frames 4b, running behind the head pulley station 2, are removed and inserted as belt frames 4a in front of the rear station 3.
[20] If a strip mine layer has been mined, the reverse procedure takes place. The head pulley station 2 and the rear station 3 move forwards simultaneously. In this case, the belt frames 4a are removed and inserted as belt frames 4b. A change in length of the belt does not take place during the entire mining process. The conversion times are minimized and the belt maintains its strength.
