This article presents predictive statistical models for fragmentation in open pit mines using drill-and-blast data. The main contribution of this work is the proposing of statistical models to determine the correlations ...

This paper presents the development and experimental validation of a multizard bridge pier concept, i.e., a bridge pier system capable of providing an adequate level of protection against collapse under seismic and blast ...

Back in 2000, CSN along with DME, conducted a diagnostic study on Hot Blast Stoves # 1, 2 and 3 of Blast Furnace # 2, after 19 years of operation and close to the end of its design campaign - originally set to last for 20 ...

This paper describes the main characteristics and advantages of convective heating system for refractory lining, compared with conventional heating systems. In addition the main results obtained are presented with its ...

For the last few decades, the effects of blast loading on structures have been studied by many researchers around the world. Explosions can be caused by events such as industrial accidents, military conflicts or terrorist ...

To control the overbreaking of an underground mining development gallery, the controlled blasting technique was proposed and as a result it was possible to reduce costs and improve the physical stability of the periphery ...

The protection mechanisms of refractory linings both at the slag and pig-iron levels associated with conventional techniques of titanium addition to the blast furnace burden were investigated. The results were derived from ...
