and crushed coal. The width of the excavation round depends on the basic dimensions of the excavating equipment and the geomechanical properties of the coal. A controlled extraction of the crushed coal from the upper excavation section can be reached by sliding the coal down via bent roof beams to the front part of the lower excavation section [7].
where fumes could travel offsite and impact nearby residential areas. Any factor that may change the chemistry of an explosive during detonation (such as the balance of fuel to oxidizer) has the chance to upset the oxygen balance designed for the mixture. Such factors can include: • Insufficient charge diameter, • Inadequate priming,
