ABSTRACT

‘Rat-hole’ mining method is a primary and conventional process of coal extraction in several parts of India as well as in the world. The study has been done on the basis of samples collected in different seasons to know the nature of dispersion and also human activities have also been considered to know its impact. It has been observed that low dissolved oxygen (DO) and high BOD, high TSS and TH are some of the bio-physical parameters which characterize the degradation of water quality. The inter dependency among different climatic variables and in all cases the correlation value is 1, i.e. <0.5. It is seen that the amount of rainfall is heavy, then excessive amount of waste materials are flow through this runoff and the physical properties of water become affected. So it has been argued that the water bodies of the area are the greatest victims of the coal mining. This work will analyse the various parameters of Harabhanga pit water bodies which can able to show the nature of water quality and will also aiming on the seasonal dependency on the water bodies. OCP water based sustainable developmental strategies that can be useful in mitigation of the environmental problems and rehabilitation of degraded ecosystems and it have also been suggested that these strategies will be prepared on the basis of local needs. Key words: Abandoned OCP, BOD, Dissolved oxygen (DO), Sustainable development, TSS, TH
