This paper describes dust explosibility research in full-scale experimental mines and a 20-L laboratory chamber at the U.S. Bureau of Mines and in a 1-m3 laboratory chamber at Fike Corporation. The purpose of this research is to improve safety in mining and other industries that manufacture, process, or use combustible dusts. As part of this work, carbonaceous dusts with a wide range of volatilities and various particle size distributions were studied. Laboratory data on the minimum explosible concentrations of predispersed dusts were comparable to mine data for nominal dust loadings that were dispersed by the aerodynamic disturbance from a gas ignition zone. Recommendations are given on the limitations of small-scale testing such as “overdriving” by too strong of an ignitor. The effect of dust particle size on explosibility data is illustrated for coal and aluminum dusts. For both dusts, the finest sizes were the most hazardous. The inerting requirements for preventing explosions were also measured in both laboratory and large-scale systems. All the data show relatively good agreement between the laboratory and the large-scale tests. 相似文献

There has been a resurgence of interest in industrial policy in higher income as well as in emerging and still developing economies, in part due to a renewed interest in the role of economic structure, with industrial policy interpreted as interventions designed to shift resources into higher return, higher growth activities. Dialogue with the private sector is critical but central to policy choice is how far policy should be applied on a vertical as opposed to a horizontal basis. This paper surveys the techniques available to guide selectivity, focusing in particular on trade-based indicators. It concludes that whilst in practice some selectivity is necessary, there is a limit as to how far this can be guided by objective indicators and flexibility and experimentation will be required in the application of policy. 相似文献
