MINE CLOSURE USING REMOTE SENSING AND GIS (SPECIFIC TO AGRICULTURE)

Our work is about building a query based GIS system which will guide the mining company to take up activities that will move towards reclaiming the land for that particular usage. For example if the company finds it suitable to reclaim the land for agricultural usage especially for paddy, paddy requires lot of nitrogen for its growth. So nitrates and nitrites need not be removed in the closure process. This makes the closure more economical and beneficial as well. The query based system will take into account the topography of the land, the mineral mined and the soil conditions and will help in making decisions about the type of usage and way of mine closure. The objective is to make all mining activities environment friendly and make sure that to the extent possible the remains of the mines are used constructively for the agricultural growth of crops. We are using an interactive GIS and ArcGis as the front end. Erdas Imagine is used to process the satellite images. The inputs required are the satellite image of the area, temperature of the area, the type of mine, the rainfall patterns, and the soil nutrient content. The output would be the most suitable closure plan with particular emphasis on a crop. The agricultural requirements of the crop would be fed into the system and the system would automatically choose the best fit crop. Mine closure can be made more economically favorable by this targeted approach.
