Abstract

The demand for washed coal in India has led to the planning of washeries. The sources of air pollution in washeries are described is this paper. A number of new washeries are going to be installed within the vicinity of Jharia Coalfield in eastern India to fulfill the demand for washed coal. Air pollution monitoring was conducted at four coal washeries of Bharat Coking Coal Ltd. (BCCL). Methods adopted for selection of monitoring stations and sampling and analysis of ambient air quality are discussed. Suspended particulate matter (SPM) concentrations in an industrial area, a residential area, and a sensitive area such as a hospital were found to be high and to exceed the limit specified by the Indian Pollution Control Board. NOx and SO2 concentrations in some areas were also found to exceed the specified limits. A high percentage of respirable dust in SPM indicates a health hazard. Benzene-soluble material was found to be 40%, which can be fatal to human health. Suppression measures are discussed for dust, and control measures for air pollution in coal washeries are proposed.
