Vol. 2, Iss. 1

460--471

The article presents the principles of safe cutting of rocks prone to generate igniting methane sparks. A list of methane ignitions and explosions from the sparking of rocks caused by cutting with road header was given. Unusual case of methane ignition in conditions of full technical and technological protection of roadway development is discussed. In conclusions, the importance of an individual approach to geological and mining conditions in the case of the need to cut sparking rocks was emphasized.
