Abstract
Until now there has been no systematic use of data for both exploration and monitoring. Remote sensing, from aircraft and satellites, is a powerful technique in mineral prospecting which can be adapted for methane emission and other important aspects for environmental monitoring. So the collected data from remote sensing together with ground measurements in a GIS, a computer database can used to correlate spatial data with an underlying map of the area.
As known deposits of valuable minerals are consumed, the mining industry needs to employ increasingly sophisticated techniques in its search for new reserves as well as for the exploration too. At the same time, mining companies are becoming more sensitive to environmental issues and are looking for new tools to help them monitor and reduce the damaging effects of their operations with the help of GIS & its latest tools. The main technical challenge was to make the system sufficiently flexible to accommodate the requirements of all the potential users.
To this end, we attempted to provide general information about the types and uses of data for the particular phases of a mining project from exploration, through development and restoration. Considering the new types of data available since our own data acquisition phase, this strategy has proven prudent. Geoscience in India is contributing to increase mineral exploration investment through innovative geoscience research and information that provides new insights into India's mineral potential. The work is facilitating more targeted and cost-effective exploration strategies by industry.
Scientists of Central Mining Research Institute with experience in mining, geodata processing and remote sensing have collaborated in using various spatial analysis methods, including a Geographical Information System (GIS), to correlate a wide variety of geographical, geological, geophysical, meteorological and industrial data of interest to the mining industry. Much of the information was gathered by different scientists and supporting staffs at various coal-fields area, which is very much valuable for monitoring the activities of the mining industry.
