On nondurable slaking rock material such as coal measure rock,water – aswater content in pore space – will control the oxygen diffusion and slaking, thus oxidation rate of sulfide mineral contained in rock. Present study is conducted in order to investigate acid mine drainage release behavior of sulfide mineral containing rock under diverse water content condition affected by different water pouring interval. Five columns with diameter 50mm and 150mm in height were used for leach test. Each column was experienced different pouring interval and flushed in each cycle (6 days) for as much as 9 cycles by using de-ionized water. Leachate as a result of flushing was then measured for pH and electric conductivity as well as sulfate and metal content. Water balance and leachate characteristic due to various water pouring interval were discussed in this paper. © 2012 Taylor & Francis Group, London.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Acid mine drainage,Leachates,Metal content,Mine waste rocks,Oxidation rates,Oxygen diffusion,Pore space,Release behaviors,Rock materials,Water balance,Water-pouring,Weak rock[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Coal mines,Problem rocks,Risks and hazards,Weak rock[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
