Acid Mine Research Paper

The effluents from coal washing plants area, the subsidence, which causes loss of agricultural land and damage to surface structures. The extent of land damages due to the caving methods of underground mining without stowing is main issue. The magnitude of mine fire problems form a major pollution source over a many areas. The impact of coal wisterias on water pollution is highlighted by a recent survey, which disclosed that one coal washers alone was discharging about 40 tons of fine coal into the Damodar River each day. The suspended coal particles cause difficulties in water works situated downstream while the deposits of ash and coarse coal particles are having endangered the spawning of fish on the

Noise levels were measured at several locations in the human settlements around the proposed mining site by using precision noise level meter. Detailed analysis of noise has revealed that there is no noticeable impact of noise in the surrounding environment. All the study sites in the residential areas exhibited a noise level well within the corresponding threshold limit value as prescribed by CPCB, both during the day and night time.

G. Land Environment

For the proposed lower kenda underground coal mine, the total area is large, and requirement of land for opening the underground mine is estimated as 34.37Ha. There is some forest landin this area. Some wasteland, agricultural field and forest area have been analyzed for their physico–chemical properties. Analysis of soil samples reveals that there is no wide variation in the natural material. Particle size analysis shows that the texture of the soil is of sandy loam in nature.

H. Biological Environment

The core & buffer zone has no endangered floral & faunal species. As, there are several floral species and faunal species area

Socio-economic Environment

The main occupation of the people in the area is service Industry likely to come up in the study area, welfare facility to be provided by the project proponent etc.

J. Plant Emissions

The stacks are major sources of air pollution from the proposed plant. The proposed plant is to be provided with necessary air pollution control devices like Electro Static Precipitators (ESP), bag filters, dust catchers etc. to control dusts and gases and also limit emission within the prescribed standard. The emission factors, air handling capacity of the proposed installation and emission norm has been used to estimate amount of emission from the proposed plant with the height of emission.

III. PRO-ADVERSE IMPACT

1. Impact on Noise Environment- During the normal operation of various plants, boilers, turbines, compressors, crushers, blowers, purging and blow downs, the ambient noise levels are expected to increase significantly with the attributes of the respective equipment, but these noise will be restricted close to the concerned equipment. Therefore all the equipment in the area will be designed/operated in such a way that the noise level shall not exceed 85
