Innovative developments in drilling and blasting techniques for rapid excavation of drivages in mines

摘要

Infrastructure development has been gaining importance over the years both from the economic perspective and as an area of sustained growth. Presently, the infrastructure sector in India accounts for 26.7% of India's industrial output and is therefore an effective tool to balance the economy. Over the last four years the infrastructure industry in India recorded a growth rate of almost 8.5%. Now the Indian government has announced further investment in infrastructure in their 12th Five Year Plan (2012-2017), with which substantial growth has grown in the planning of tunnels, hydroelectric projects, storage caverns, metro projects and underground projects within the rail, road, sewage and hydropower sectors. To achieve time bound programmes of construction of mega projects in a period of four to five years, modern methods of rapid tunnel driving are being considered as only solution to achieve a high rate of progress.
