MECHANISM OF COAL AEROSOL EXPLOSION DEVELOPMENT IN AN EXPERIMENTAL MINE WORKING

Today there is not enough scientific data on the energy level and velocity of an explosion in actual mine workings, which have a cross-sectional area larger than experimental workings. The objective paper to justify parameters workings based disclosure fire front development mechanism when coal dust explodes working with limited area. These studies can be basis for choosing speed action strength means localization explosions. main research method analytical method, analysis results explosions theoretical substantiation regularities additional further extrapolation conditions It proposed supplement idea about sections dynamics, i.e. initiation, explosion, crater, determine characteristic explosive velocity: maximum initiating velocity, average crater. was established that during methane initiation at boundary between dusting zones, situation hybrid mixture air, has its own indicators. A linear dependence generated aerosol plane established. This makes it possible use testing from certain deposits small-scale set-ups protective
