Damage Analysis for Coal Lance in Blast Furnace
Advanced Materials Research, 2011Pulverized Coal Injection (PCI) is a key technology in modern ironmaking by blast furnace and the life of injection lance has a great influence on PCI operation and on normal running of blast furnace. It is found that the main reasons for the failure of the lances are their outer surface oxidation and the inner surface erosion through monitoring some ...

Damage cost of the Dan River coal ash spill
Environmental Pollution, 2015The recent coal ash spill on the Dan River in North Carolina, USA has caused several negative effects on the environment and the public. In this analysis, I report a monetized value for these effects after the first 6 months following the spill. The combined cost of ecological damage, recreational impacts, effects on human health and consumptive use ...

Cytogenetic damage in workers from a coal-fired power plant
Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2007The aim of this study was to investigate the genotoxic risk to workers occupationally exposed to coal combustion products in Afsin-Elbistan A power plant, located in south-eastern Turkey. We analysed chromosomal aberrations (CAs), polyploidy, sister-chromatid exchanges (SCEs), and micronuclei (MN) in 48 male workers without a history of smoking ...

Oxidative DNA damage in peripheral blood lymphocytes of coal workers
International Archives of Occupational and Environmental Health, 1995Reactive oxygen species are important mediators of both mineral dust-induced (malignant) lung disease and in vitro DNA damage. Therefore, we studied in vivo oxidative DNA damage in coal workers who had been chronically exposed to silica-containing dust.

Damage to underground coal mines caused by surface blasting
International Journal of Surface Mining, Reclamation and Environment, 1993ABSTRACT An investigation of the potential damage to underground coal workings as a result of surface blasting is described. Seismometers were installed in a worked out area of an underground mine, and the vibrations caused by nearby surface blasting recorded. These measurements were used to derive peak particle velocities.

Coal Permeability Damage Caused by Production Pressure Difference
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2012Abstract Due to the special physical and mechanical properties and gas production mechanism of coal reservoirs, the changes of their physical properties are different from those of conventional reservoirs during the coalbed methane development process, of which the dynamic change in permeability is the most significant.

Microscopic damage field in coal induced by water jets
Journal of Loss Prevention in the Process Industries, 2018Abstract This paper uses experiments and simulations to investigate the fragmentation process of coal subjected to water jets. The experiments are conducted using computed tomography (CT) and digital image processing technology to reconstruct the damage field of an impacted coal core, and a numerical model is established based on the arbitrary ...
