“…of aerial extension which is at least 100m in thickness reaching 185m in the southern part of the mine area and extends from beneath a shallow covering of Barind clay residuum to its geologically unconformable contact with the groundwater measures [1]. The Dupitila formation and Gondwana sandstone, that is known to be hydraulic continuity with the coal seam VI, North Slope of the Platform, Platform Flank Zone represents a major potential hazard to the mine from water inflow [1,25,26]. BCM is an independent Gondwana coal-bearing basin, which is controlled by half-fault Graben and unconformably laid on the denuded Archean Basement Complex [1,26].…”

“…BCM is an independent Gondwana coal-bearing basin, which is controlled by half-fault Graben and unconformably laid on the denuded Archean Basement Complex [1,26]. Based on brilling data, the strata can be divided into four units such as Basement complex, Gondwana group, Dupi Tila Formation and Barind Residuum Clay and their Lithology [25,26], average thickness and hydrology have been shown in Table 1. …”

Abstract:In order to evaluate the heavy metals contamination of groundwater in Barapukuria Coal Mine (BCM) area and its vicinity, nine groundwater samples from different location, two waste water either treated and/or untreated that were used to irrigate in and around the coal mine areas, three surficial soil samples (~20cm depth) and a coal dust sample were collected during March, 2015. The samples were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). Each sample was analyzed for As, Mn, Fe total , Cu, Pb, Zn, Mo, Ni, Co, Cr, Cd and Hg. It was found that As, Cu, Pb, Zn, Mo, Co, Cr, Cd and Hg did not exhibit significant elevated levels, but concentration of Mn, Fe total and Ni ranging from 0.15 to 3.85mg/L, 0 to 1.88mg/L and 0.01 to 0.09mg/L respectively both in groundwater and mine waste water samples exceeded the World Health Organization (WHO, 2004) drinking water guideline values of 0.4mg/L of Mn, 0.3 mg/L of Fe and of 0.02mg/L of Ni. Similarly the mean heavy metal concentrations in soils were below the Bangladesh standards for all heavy metals but the maximum values of Co (137.25 to 245.24mg/kg), Cr (139.02 to 243.38mg/kg) and Hg (0 to 24.28mg/kg) also exceeded the maximum acceptable limit of Food and Agricultural Organization (FAO, 1992) (Co of 50mg/kg, Cr of 100mg/kg) and Environment Agency (EA, 2009) (Hg of 1mg/kg) guideline standard. However, the coal dust was not above the guideline recommended limit for any elements. Therefore, this study reveals that the use of treated and/or untreated coal mine waste water for irrigation has increased the risk of heavy metals contamination in groundwater and causing potential health hazards in the long time term.

“…Flooding of the mine from breaches in the Upper Dupi Tila aquifer occurred frequently during the development of the mine in 1998. When the mining walls had been extended to a total distance Khan, 1991;Khan and Chouhan, 1996). of about 1200 m, roof pressure increased dramatically and a small amount of water flowed into the mine from several locations along the roof.…”

“…These three plates form three major tectonic zones in Bangladesh ( Fig. 1): (i) a platform flank zone in the west named the Dinajpur Shield and Platform, (ii) a central deeper basin, the Bengal Basin, and (iii), the folded belt in the east, known as the ChittagongTripura Fold Belt (Khan, 1991;Khan and Chouhan, 1996;Alam et al, 2003). Each of these zones is distinguished by a unique tectonic and stratigraphic history (Alam et al, 2003).…”
