    Notes: 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.

    Status of air pollution caused by coal washery projects in India (1995)
    Springer
    Environmental monitoring and assessment 38 (1995), S. 97-105

    Notes: Abstract The importance of coal washeries in India is growing as local coals have a high ash content. At present, there are 23 coal washeries with an annual rated input of 45 Million Tonnes. During the various operations in washeries, large amounts of dusts and gaseous pollutants are generated. Four coal washery projects were surveyed to study their air pollution characteristics. Air monitoring stations were set up in local industrial, residential and sensitive areas and air pollution samples were collected along with micro-meteorological data. Diurnal variations of SPM, SO2 NOx and CO are discussed. SPM concentrations were found to exceed the permissible limits at all locations. SO2 and NOx were also found to exceed the permissible limit in residential and sensitive areas. It was observed that about 50% of the dust particles were less than 10 µ in diameter. Benzene soluble matter in SPM ranged from 45–62%.

    Notes: Abstract Every mine in India has to obtain environmental clearance fromthe Govt. Air pollution is one of the most important parametersto be considered in preparing an EIA. However, there is no welldefined method for predicting thr air pollution impact due tomining. Increasing trend of opencast (O/C) mining leads toproduction of huge quantities of dust. Emission factor data havebeen utilised to quantify the generation of dust. The projectunder study is one of the largest opencast project (OCP) forcoking coal. The main sources of air pollution have beenidentified. The rate of emission per unit of a given activityknown as an emission factor has been utilised, taking localfactors into account. It has been estimated that due to topsoilremoval, overburden (O/B) removal, extraction of coal, sizereduction generated 7.8 t of dust per day. Wind erosiongenerated 1.6 t of dust per day and the whole operationproduced dust which accounted for 9.4 mt/day. They cause airpollution in the work zone and surrouding locations. Themethodology adopted may be used to quantify generation for otherprojects also.
