The CPDM also has a heater element to drive off excessive moisture and a momentum compensator, which eliminates frequency changes attributed to movement. Fugitive Dust is another coal mine concern. The term fugitive dust refers to particulate that is lifted into the air either by man-made or natural activities in large open areas.
Underground Coal Mine Mitigates The Risk Of Fire By Using Fire-Resistant Hydraulic Fluid To mitigate the risks of using a mineral oil based hydraulic fluid a large underground coal mine in southern West ia was using QUINTOLUBRIC® 888-68 an MSHA approved fire-resistant hydraulic fluid in their hydraulic systems.
It's very challenging to control dust from mining processing equipment, such as crushing, screen, and conveyor transfer points. Both the Mine Safety and Health Administration (MSHA) and the Environmental Protection Agency (EPA) are working with mining companies to reduce dust emissions around mine sites to protect people and the environment.

2 Mine dust impacts Mines can be classified as either underground mines or open pit mines. In some cases a combination of open pit and underground mining occurs, although usually sequentially in the mine life-cycle, rather than simultaneously. At underground mines the rock dumps, tailings dams, and load-out facilities are the
However, some form of water control is usually required to keep the mine pit from becoming a lake, if the mine is situated in a climate of considerable precipitation or if any layers of the pit forming the mine border productive aquifers. Open-pit mining is to be considered one of the most dangerous sectors in the industrial world.

DUST CONTROL PRACTICES IN INDIAN COAL MINES Dust control involves either dust consolidation or dust capture. Dust consolidation is normally practiced for settled dust which becomes airborne in favourable condition e.g. haul roads of open cast mines. Dust collection or capture is resorted to when it is airborne.
