Effects of limestone strip mining on benthic
In contrast to coal strip mining characterized by high total acidity and iron concentrations with decreased total alkalinity and pH, limestone strip mining showed only a slight increase in total acidity and bicarbonate alkalinity, and no increase in iron concentration due to the formation of heavy deposits of ferric hydroxide In this paper we have reviewed the status of limestone mining and its environmental implications in Meghalaya, India Results on impact of limestone mining on quality of water, soil and air, degradation of forest and availability of water are summarized and discussedLIMESTONE MINING AND ITS ENVIRONMENTAL Limestone mining can affect ground water conditions Limestone deposits often occur in association with karst, a topography where limestone slowly dissolves away underground The deposits result inEnvironmental Hazards of Limestone Mining

Evaluation of the Effects of Length on Strength of Slender
Another consideration for limestone mines is the type of failure that can occur in these high openings with slender pillars It has been noted in hard rock mines that pillar spalling and failure occur at stress levels well below the expected rock and pillar strength (Stacey and Yathavan, 2003) This has been attributed to brittle Environmentally, potential negative effects of mining can include air, land/soil and water pollution of different kinds Mining produces potentially hazardous/toxic tailing waste, and can leach toxic chemicals, heavy metals and air pollutantsThe Potential Negative Effects Of Mining On The the rock mass are heavily developed at the limestone quarries in Japan, the joints and/or cracks in the rock mass have big impacts on the blasting effects such as the size of fragmented rocks Therefore, if the joint system and/or crack density in the rock mass can be known and evaluatedEffects of Rock Mass Conditions and Blasting Standard on
