The proposed model presents a rock bump (a technogeneous earthquake) as a shock wave emergence on the inside wall of a mine. In such a case, an unloading, tensile wave is generated which moves in the opposite (into the wall) direction. A shock wave is accompanied by medium motion in the direction of shock wave propagation with the velocity significantly less than that of the wave. Phenomena, occurring on the inner surface of a mine result in coal dustfall and methane dissolution in the coal that causes an explosion.

Key words: nonpotential part of geomagnetic field, Schmidt-Bauer currents, rain currents and evaporation currents.
