A COMPARATIVE STUDY OF IMPACT OF OPEN CAST COAL MINING ON AVAILABILITY OF SOIL MICRO-ORGANISMS LIKE BACTERIA, ACTINOMYCETES AND FUNGI IN BOTH MINING AREAS OF JHARIA COALFIELD AND NON-MINING AREAS (BALIAPUR AND SINDRI) OF DHANBAD, JHARKHAND ALONG WITH SIGN
Main Article Content
Coal is very important fossil fuel resource which fulfills the ultimate energy requirements. Jharia coalfield is known for its prime coking coal resources in the world. For effective coal extraction open cast mining is done on large scale in JCF. Due to blasting, drilling and excessive use of explosives the top most layer of the soil gets severely damaged. The availability of soil nutrients gets completely disturbed by open cast mining activities due to which presence of soil micro-organisms like bacteria, actinomycetes and fungi also gets affected. Availability of soil micro-organisms like bacteria, actinomycetes and fungi etc. is very significant because such organisms play major roles in promoting effective soil ecosystem. This paper presents the results of the study carried out in both mining and non-mining areas. The availability of soil micro-organisms like bacteria, actinomycetes and fungi etc. in both mining ( Lodna and Bastacola) and non-mining areas (Baliapur and Sindri) was assessed and compared. It has been observed that in non-mining areas the stable and effective soil environment have excellent availability of organic matter and all other physico-chemical parameters due to which micro-organisms like bacteria, actinomycetes and fungi are found in good numbers whereas mining areas do not have similar soil environment and hence due to degraded soil ecosystem, poor availability of organic matter the soil micro-organisms remain in lowest number. The present comparative study of soil are very vital to understand that how open cast mining activities are damaging the ideal soil environment. The obtained results are also very beneficial for planning the rehabilitation programmes for Jharia coalfield so that degraded land can have ideal soil environment and improved Biodiversity of soil insects.
