EFFECTS OF ENVIRONMENT IN COAL EXPLOITATION IN LIUPANSHUI

Liupanshui is the biggest source of coal production in the south of Yangzi River.Several million tons of gangue are produced in coal exploitation every year,and thus a large area is occupied by the gangue and soil,water is polluted by harmful ions of heavy metal produced from the gangue.The coal dust in transportation piles up,causing several diseases.The year average content of suspended solid is 253 mg/L in Shancha River and 936 mg/L in Xiaohe River,caused by waste water produced in mine and coal processing,which are beyoned the national standard.The gas produced by the power plant of coal and made indigenous methods coking coal by township enterprises is one of the main sources of air pollution.Statistics show that about 260 hundred million standardized cubic meter of waste gas is poured into air by coal factories,power plant and indigenous methods coking coal.The waste gas contains about 50 thousands smoke dust and about 30 thousands tons of SO_2,hence the main pollutant in the air.
