Hazardous area classifications (SANS10108)

2014-1-15  Area classification (in South Africa better known as the classification of hazardous locations) plays a pivotal role in explosion prevention i.e. the technology of preventing explosions due to flammable gases, vapours, mists, dusts and fibres in surface industry and mines. Area classification can be defined in several ways, for example

Modeling of such a conditional situation requires mapping the surface elevation of the coal bed roof, which, similar to thickness, is only known at the drill-hole intersections. On the contrary, the land-surface elevation is known without error (fig. 27).

Classification of Coal Resources Using Drill Hole

Based on a case study in a coal field consisting of three coal seams, the geostatistical approach produced the smallest distance on seam-3 as the optimal borehole range in the research area.
