Band experience

As Bandfahrung is known in mining a form of mechanical driving experiences , the implementation thereof miners in the sections mounted belt conveyor use. This form of passenger transport is a special feature that is only used in underground mining. It is forbidden for non-factory people (visitors) to travel to the belt.

Basics and history

In the case of mines with large pit fields , the working time on site is considerably reduced by the long travel routes. This was already noticeable in the second half of the 1970s, as here in the mines the distances that the miner had to cover to his place of work were often several kilometers long. Long mining stretches in particular were a burden for non-mechanical driving due to the unfavorable mine climate there. Without additional underground passenger transport systems, it is not possible to cover such large distances in the shortest possible time. In addition, the long routes, if the miner has to cover them on foot, also reduce the miners' productivity and motivation. This manifests itself in the fact that the miners often need an additional break before starting their work. Since the 1960s, the belt experience was introduced in several mines. In modern mining, especially in hard coal mining, this type of machine driving is part of the standard for underground passenger transport.

requirements

The belt drive may only be used in a mine if permission has been given by the responsible mining authority. In order to be able to carry out the belt drive, certain safety-related equipment must be available, and the belt conveyor in question must also receive special modifications and attachments. First of all, the belt speed must be limited to 2.5 meters per second. In exceptional cases, this travel speed can be up to 3.2 m / s. If belt conveyors with a higher speed are used, they must be designed in such a way that the belt speed for moving the belt is switched to the permissible speeds. Depending on the local conditions, the belt travel can be set up on both the upper run and the lower run of the belt conveyor so that the belt can be run in both directions. So that the miners can safely get on the harness and get off again at the destination, platforms (platforms) must be installed as access and descent points at belt height. These platforms are usually mounted on the side next to the belt construction or above the belt, from which the miner can then ascend or descend via stairs. In the case of belt conveyors that are used exclusively for moving the belt, there are also head-to-head descents or head-to-head slides that the miner can use to descend. So that the miners do not go over the target at the end stop and are thus endangered, special override protection must be installed here. In addition to electronic monitoring barriers, mechanical gates that open when driven over and thus shut down the belt conveyor via the control are installed. In addition, additional mechanical safeguards such as safety nets or scrapers are installed at the ends. These are often connected to switches that stop the belt conveyor. There are also other mechanical safeguards such as retractable support frames or retractable flat rollers.

execution

Image wanted

The miner enters the belt via the climb. The belt drive is carried out in such a way that the miner always looks in the direction of travel while driving. As a rule, the tape is used lying on the tape. In the case of downward stretches, the belt drive is usually carried out while sitting on the belt. In the area of the descent points, the miner changes his position on the harness and kneels on the harness or stands so that he can easily leave the harness on the descent.
