Mine attendant

from Wikipedia, the free encyclopedia

As mine control station is known in mining a control center that serves the operation of a mine to monitor. It is located at a central point in the surface area of the respective mine. Almost all operations in the mine are monitored and, for the most part, controlled in the mine control room.

Basics and history

At the beginning of the second half of the 20th century, mining in Germany, especially hard coal mining , was faced with the task of rationalizing mines both above and below ground due to the high cost pressure . There were major problems, especially in the underground area. Due to the fact that the mine buildings of the individual mines often had large dimensions and the management was usually unable to react promptly in the event of malfunctions, there were often long downtimes. In order to reduce production losses, a central point was planned, which should be located above ground on the respective mines. To do this, it was necessary to transfer the individual operating states from the respective mining operations to the surface using communications and telecontrol technology . In 1960, one of the first mine control rooms for the Ruhr mining industry went into operation at the Jacobi colliery . In addition to the transfer of the operating conditions of the mining operations also should firedamp concentration in the mine workings by appropriate weather gauges are transmitted to the pit waiting. This meant that time-consuming weather measurements by weather people could be omitted. The importance of the mine control room and the continuous transmission of the measured values ​​became clear during a local mine fire at the Schlägel & Eisen colliery . Due to the continuous reading of the writing implements by the mine maintenance personnel, the mine rescue service could only be alerted relatively late, but all but one of the miners could be rescued. The mine maintenance team was also able to improve the general operational sequence, which significantly reduced the downtimes caused by malfunctions.

Technical Equipment

In the early years the mine control room was equipped with only a few devices. The operating status of the underground operations was displayed on a mosaic wall with indicator lights , and the mine attendant was connected to the mining operations by telephone. Over the years, recording devices with writing strips were added. In addition, warning messages when limit values ​​were exceeded were displayed both optically and acoustically. In order to be able to transmit all measured values, they were transmitted using audio frequency methods. In this way, up to 24 individual values ​​could be transmitted from the mine to the mine control room via a two-wire line. Control commands could also be transmitted underground from the mine control room. Towards the end of the 20th century, the mine control rooms were equipped with modern computer technology. The individual computers were networked with one another on different levels. The operating status of the mine is displayed on screens. This enables the mine control room to read almost all operating states at any time. In addition, the staff in the mine control room can communicate with the miners underground at any time via radio. Modern mine control rooms are air-conditioned so that employees can work optimally .

Duties of the mine attendant

The tasks of the mine attendant are very extensive. The composition of the weather in the entire mine is checked. For this purpose, all weather-relevant devices and machines such as B. monitors the pit fan. The data from almost all weather measuring points are collected and evaluated in the mine control room. B. The amount of mine gas content in the weather or the amount of weather are displayed optically or acoustically if necessary. Another important task is to control the drainage system . The level of the pit water is regularly measured at certain points and displayed and checked in the mine control room. In addition to these activities relating to mine safety, the operating status of production in the operations control room, which is a sub-area of ​​the mine control room, is monitored. In addition to more than days of mining machines such as the coal plow controlled and the complete route promotion be monitored and controlled if necessary. The operating personnel can read the operating status of the shaft conveyance and also the amount of coal conveyed at any time. If necessary, the mine supervisor will initiate the necessary countermeasures in the event of operational disruptions and inform the responsible management personnel of the mine.
