Guidelines for mine water management Mining influences the quality and quantity of water in the mine area R and in its surroundings and changes hydrological conditions. H Although mining companies have long been conscious of the I importance of water management, they still face environmental problems.
Control: this relates to how the water to the system is controlled. For example, it may be controlled by the presence of coal on the conveyor or by the motion of the belt, so that water can be isolated before entering the system. Filter: this ensures the water is sufficiently clean or free of contaminants, so that the system operates correctly.
Oct 11, 2009· Abstract: In the coal mine water level control systems, because the variables are nonlinear, time lagged and uncertain, it is not possible to establish the mathematical model precisely. This article combines the intelligent control with the traditional automatic control device. According to the principle of the fuzzy control and the characteristic of PLC, designing the mine water level fuzzy ...

Oct 05, 2010· Water is used to extract, wash, and sometimes transport the coal; to cool the steam used to make electricity in the power plant; and to control pollution from the plant. The acts of mining and burning coal, as well as dealing with the waste, also can have major effects on water quality.
Coal Mining. In addition to the sources of pollution listed above, coal mining produces coal slurry (also known as coal sludge) in the process of beneficiation. The coal is washed with water and chemicals as a way to help it burn more efficiently [22].
Automation is not new to mining, but it is generally more basic in mines than in other industries and is often limited to simple control of motors, equipment or certain parts of processes. Further, mines tend to have a large number of independent pieces of equipment and systems from different suppliers.
