At that time, excavator machines and sophisticated drills had failed to bore through the debris and the daunting task was eventually handed over to 12 'rat-hole miners'. The dozen men, largely from Uttar Pradesh and Madhya Pradesh and employed with a Delhi-based firm, as a final resort manually carved through the debris. The authorities had earlier used excavator machines, two types of auger machines and vertical boring machines.Aligning with the national geospatial policy's goal to create 'digital twins' of the country's major cities and towns by 2035, the Survey of India (SOI) - custodian of India’s map - has, in a first-of-itskind initiative, signed an agreement with an Indian private mapping company, Genesys International, to mirror urban landscape and physical assets with precise details and produce their 3-D maps.
