The interaction mechanism between the combustion products of pulverized coal injected and coke in the raceway of blast furnace was studied through thermodynamic calculation and experiments. The results indicated that additives significantly affected the melting property of coal ash in high temperature zone. Although the unburnt char, raw coal ash, and catalyzed coal ash failed to wet the coke surface,...
EIA (Environmental impact assessment) and environmental acceptance both are important part of coal mine's environmental management. The demands in EIA period are materials particular in environmental acceptance period. Then environmental acceptance can feed back important informations to EIA. Currently, there is less interaction between these two areas. This article analyzed the current situation...
In order to study geobelt effect on subgrade and mechanism of strength increment in reinforced subgrade, the author separately established their mechanics modes, analyzed the their stress state and relation, disclosed the function that geobelt change unit stress state of subgrade; Combined Mohr-Coulomb destroy standard, analyzed the relation of those subgrades unit's extreme stress state, found the...
