One of the major issues facing the mining industry in the state is the treatment of acidic effluents during and after closure of a mine. Here, in this book, genesis of AMD formation, assessment of acidic drainage in Jaintia Hills, its impact on the environment, causes and management has been addressed. The focus of the book is on development of effective methodologies for management of Acid Mine Drainage from the coal mines and restoration of ...

North Eastern region of India has a substantial deposit of high sulfur Tertiary coals, ranging from Paleocene to Oligocene period. These coals are of recent origin and have different physico-chemical attributes in comparison to other Indian coals. The general characteristics, which restrict their usage in the domestic as well as industrial sectors, are high sulfur, high volatile matter, low ash fusion temperature, highly caking and friable nat...

In the present investigation, the physico-chemical parameters of high sulphur North-east Indian coals, the problem of acid mine draiange (AMD) formation in the mining sites and remediation options have been reported. These coals are charaterized by low ash, high volatile, sulphur and friability. AMD produced in these areas releases highly acidic effluents enriched with metal contents. Acidic mine waters was found to be reddish brown to yellow ...
