Optimization of blasting parameters in opencast mines
Drilling and blasting are the major unit operations in opencast mining Inspite of the best efforts to introduce mechanization in the opencast mines, blasting continue to dominate the production Therefore to cut down the cost of production optimal fragmentation from properly designed blasting pattern has to be achieved Proper adoption of drilling and blasting can contribute significantly In the ironore mines of Singhbhum (Bihar), eg, Noamundi, blasthole drilling is done to break vast quantities of ore, by using liquidoxygen explosive Working in the Kargali coalseam (Bokaro coalfield), one of the thickest seams in India, are mainly of the opencast typeOpencast Mining in India Blogger The machines deployed in the opencast mines, at the crushing and ore preparation plant have to be of matching capacities At Kudremukh Iron Ore Project, one of the largest opencast mines in India, the capacities of some of the machines are : shovels 107 m 3 , production trucks 108 te, front end loaders 10 m 3 , electric drills for 310 mm dia List of Equipment Used in Opencast Coal Mining
South Africa’s Largest OpenPit Mine NASA
People were mining South Africa’s copper and iron resources long before the advent of open pit mines Some archaeological estimates date mining artifacts back to at least 800 CE In neighboring Kruger National Park, more than 250 archaeological sites The main laws related to the mining and the environment in UK are i) Coal Mines Regulation Act (1908), ii) Mining Industry Act (1920), iii) Coal Act (1938), iv) The Town and Country Planning Act (Scotland) (1947), v) Coal Industry Act (1949), vi) Mineral Workings Act (1951), vii) Mines and Quarries Act (1954), viii) Opencast Reclamation of Degraded Landscapes due to KSB’s involvement in the iron ore industries in Brazil and Australia demonstrate two different approaches to dewatering, both employing vertical multistage pumps” In Brazil’s Minas Gerais State open pit iron ore mines excessive ground KSB open pit dewatering in mining demands durable
