state four effects of and dereliction
Answers
Answer:
Soil degradation and erosion, groundwater lowering, spring desiccation, and farmland damage affect areas adjoining the mines. Tailing ponds, pest holes, dust hazard, water affect both mine sites and adjoining tracts.
Explanation:
Mining and quarrying bring unmistakable negative impacts to human habitats. Entrepreneurs starting new projects on mining-related activities should be aware of origin and product-specific such impacts. This paper presents a classificatory approach from five specific standpoints encompassing all possible components of land dereliction. To formulate such classifications, four different mining sites are surveyed to determine the forms and processes of land dereliction associated with four different types of mining and quarrying activities. The four cases are related to underground coal mining, large-scale mechanized opencast coal mining, a large-scale non-mechanized basalt stone quarrying, and medium-scale sand quarrying, situated in India. Land dereliction forms and processes may be viewed in terms of the areas affected by them. Mine sites are mainly affected by overburden dumps, waste dumps, abandoned pits, subsidence pits, pit-wall slumps, and mine fire. Among the common processes, all types of mining areas are not affected equally.
