More DetailsAs mining progresses, this pressure can be violently released resulting in an outburst. Therefore, a coal or gas outburst is a sudden and violent expulsion of coal or gas from the surrounding coal mass in longwall mines. In order to assess the risk of seismic geohazards in a burst-prone coal mine, the moment tensor inversion technique is used [7].
