Abstract
A method, system and access station for passage control of mine vehicles. Mine vehicles are transferred between an operation area and a manual area through one or more access stations between which there is an intermediate space, to which the mine vehicle to be transferred can be driven. When the mine vehicle is in the intermediate space, at least one access gate is closed.
Claims9
A method for passage control of an unmanned mine vehicle, the method comprising:
- limiting in a mine at least one predefined operation area where one or more unmanned mine vehicles operate;
- preventing unallowed access of the unmanned mine vehicle to a manual area limited outside the operation area,
- transferring the mine vehicle from the operation area to the manual area or vice versa through at least one access station, the passage station being arranged between the operation area and the manual area;
- performing the transfer of the mine vehicle in the passage station through a first access gate and a second access gate and further through an intermediate space between the access gates;
- and, during the transfer of the mine vehicle, keeping at least one access gate, closed at a time.
A passage control system of a mine, the system comprising:
- at least one operation area for at least one unmanned mine vehicle;
- at least one gate for preventing unallowed access of the unmanned mine vehicle to a manual area outside the operation area;
- means for opening and closing the gates limiting free access of mine vehicles
- at least one access station, which is arranged between the operation area and the manual area and through which the mine vehicle is arranged to be transferred from the operation area to the manual area and vice versa;
- and wherein
- the passage station comprises two openable and closable access gates arranged successively at a distance from each other;
- the first access gate is in the operation area side and the second access gate is in the manual area side;
- there is an intermediate space between the first access gate and the second access gate;
- and the passage control system is arranged to control the passage station so that when the mine vehicle is in the intermediate space, at least one access gate is closed.
A passage station for mine vehicles, the passage station comprising at least one gate, which is arranged in a mine between an operation area limited for unmanned mine vehicles and a manual area limited outside the operation area, and through which access station the mine vehicle is arranged to be transferred from the operation area to the manual area and vice versa, and wherein
- the passage station comprises two openable and closable access gates arranged successively at a distance from each other;
- the first access gate is in the operation area side and the second access gate is in the manual area side;
- between the first access gate and the second access gate there is an intermediate space, to which the mine vehicle can be driven through an access gate;
- and the passage station comprises at least one control device, which is arranged to control the passage station so that when the mine vehicle is in the intermediate space, at least one access gate is closed.
