Abstract

A management system includes an input device provided to a loading machine that performs, after a first loading work of loading a load onto a first haul machine positioned at a first loading position at a loading site of a mine is ended, a second loading work of loading a load onto a second haul machine that is already positioned, during the first loading work, at a second loading position different from the first loading position, and a processing device to which an operation signal generated by the input device is to be output, wherein the processing device specifies a start time of the second loading work based on the operation signal generated by the input device at a time when the first loading work is ended.

Claims

1. A management system of a mining machine comprising:

an input device provided to a loading machine, the loading machine performing, after a first loading work of loading a load onto a first transporting machine positioned at a first loading position at a loading site of a mine is performed and ended by the loading machine, a second loading work of loading a load onto a second transporting machine that is already positioned when the loading machine is performing the first loading work, at a second loading position different from the first loading position, the first loading position and the second loading position being located on both sides of the loading machine; and

a processing device which receives an operation signal generated by the input device and which is placed in a different position from those of the loading machine and a transporting machine,

wherein the processing device specifies a start time of the second loading work of the second transporting machine positioned at the second loading position, by the loading machine, based on the operation signal generated by the input device at a time when the first loading work is ended, and outputs a vehicle deployment instruction corresponding to the operation signal to the first transporting machine.

2. The management system according to claim 1, wherein the processing device specifies an end time of the second loading work based on the operation signal generated by the input device at a time when the second loading work is ended.

3. The management system according to claim 2, wherein the operation signal generated by the input device at the time when the second loading work is ended includes an instruction signal for the second transporting machine to leave the second loading position.

4. The management system according to claim 1, wherein the operation signal generated by the input device at the time when the first loading work is ended includes an instruction signal for the first transporting machine to leave the first loading position.

5. The management system according to claim 1, comprising:

a position detection device that detects position information of the second transporting machine, wherein the processing device calculates a wait time length from a time when the second transporting machine arrives at the second loading position to a time when the second loading work is started, based on a detected result by the position detection device and the operation signal generated by the input device at the time when the first loading work is ended.

6. The management system according to claim 5,

wherein the transporting machine travels at the loading site and a dumping site where a dumping work of a load is to be performed, and on a haul road connecting the loading site and the dumping site, and

wherein the processing device specifies a start time of an operation of the second transporting machine travelling in a loaded state, based on the operation signal generated by the input device at the time when the second loading work is ended.

7. The management system according to claim 5, wherein the processing device specifies, based on position information of the second transporting machine output from the position detection device, a start time and an end time of at least one of an operation of travelling of the second transporting machine in an unloaded state, an operation of moving to a loading position at the loading site after a wait state at a wait position at an entrance of the loading site is released, and an operation of having a load loaded by the loading machine at the loading position.

8. The management system according to claim 1, wherein the processing device calculates a time length required for a cyclic operation of the second transporting machine moving between the loading site and a dumping site where a dumping work of a load is to be performed.

10. The management system according to claim 1, wherein the first and second loading positions are set, at the loading site, on both sides of the loading machine, and the second transporting machine is positioned at the second loading position while the first work for the first transporting machine positioned at the first loading position is being performed.

9. A management method for managing a mining machine comprising:

receiving at a processing device an operation signal generated by an input device provided to the loading machine that performs, after a first loading work of loading a load onto a first transporting machine positioned at a first loading position at a loading site of a mine is performed and ended by the loading machine, a second loading work of loading a load onto a second transporting machine that is already positioned when the loading machine is performing the first loading work, at a second loading position different from the first loading position, the processing device being placed in a different position from those of the loading machine and a transporting machine, the first loading position and the second loading position being located on both sides of the loading machine; and

specifying a start time of the second loading work of the second transporting machine positioned at the second loading position, by the loading machine, based on the operation signal generated by the input device at a time when the first loading work is ended, and outputting a vehicle deployment instruction corresponding to the operation signal to the first transporting machine.
