THE HAZARDOUS ARSENIC IN COAL MINING SPOILS OF HUAINAN

摘要

Huainan coal mine is an important coal base in east China with more than one hundred years exploitation history. There are 34 spoil heaps with 1.604km~2 total area in Huainan now. The productivity of spoils was 3.872 × 10~6 t in 2002. In 2005, Huainan was listed in the important hundred million ton coal exploitation base of China (being completed in 2010). At that time, there are more than 1.5 × 10~7 t spoils need to be dealt with every year (generally, the productivity of spoils is 15 ～ 20 percent of coal). The research on As abundance characteristics in spoils in Huainan and its geochemical anomaly is significance for the further study of As geochemistry in research area and explaining the environmental effect and management of As.
