majour hazard in open cast mine

Effects Of Mining on the Environment and Human Health

Strip mining accounts for about 40 percent of the world's coal mines but in some countries, such as Australia, open cast mines make up 80 percent of mines. Even though it's highly destructive, industry often prefers strip mining as it requires less labour and yields more coal than underground mining.
