Explosion dust particle size measurements.
In situ measurements of the sizes and concentrations of dust particles generated by the detonation of high explosives in clay soil near Leesville, La., sandy clay soil near Huntsville, Ala., and sandy soils near Orogrande, N.M. are reported. Measurements were generally made within 1 m of the surface (in one case 10 m) at distances ranging from 10 to approximately 50 m from the detonation point ...
متن کاملMass of Dust in the Martian Atmosphere
1 Estimates of the mass of dust suspended in the Martian atmosphere are derived from global and regional 9 pm opacity maps produced from Viking Infrared Thermal Mapper data. During the peak of the 1977b storm, a total dust mass of approximately 101 S gm was suspended, equivalent to 10-3 gm/cm2, or a layer 4 Lm thick. During a local dust storm near Solis Planum at Ls 227°, approximately 3.56 x 1...
متن کاملHow does limestone rock dust prevent coal dust explosions in coal mines?
Coal dust explosions in underground coal mines are pre vented by a generous application of rock dust (usually lime stone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents fl ame propagation by acting as a thermal inhibitor or heat sink. To investigate this process in more detail, a number of ex plosion experiments using various coal dust and limes...
متن کاملOverall characterization of cork dust explosion.
Explosibility and ignitability studies of air/cork dust mixtures were conducted in a near-spherical 22.7 L explosibility test chamber using pyrotechnic ignitors and in a furnace of 1.23 L. The suspension dust burned as air-dispersed dust clouds and the uniformity of the dispersion inside the chamber was evaluated through optical dust probes. The range of tested particle sizes went from a mass m...
متن کاملEvaluation of Heavy Metal Dust Pollution and their Origin in the Atmosphere of Kuhdasht, Lorestan Province
Dust is one of the environmental hazards in arid and semi-arid regions of the world. In some areas, under the influence of human activities, dust is contaminated by heavy metals. In this study, the dust of 10 stations in the Kuhdasht region of Lorestan province in four seasons of spring, summer, autumn, and winter, as well as adjacent surface soils (a total of 40 dust samples and 10 surface soi...
