Relaxing its earlier order, the Supreme Court on Friday permitted temporary mining with heavy machines within 10 km of Rajasthan’s Chittorgarh Fort for a comprehensive analysis of the impact of vibrations by mechanized mining on the country’s largest fort. The court said the 10-km area around the historic fort would be beyond one kilometre from its periphery. The court said that there would be no blasting operations. A bench of Justice R M Lodha, Justice J Chelameswar and Justice Madan B Lokur said the relaxation of its 18 Jan, 2013 order would come into effect in ten days from Friday and would remain in force for four weeks.
