Answer: A large longwall mine
Explanation: Due to the depth of a large longwall mine it is easier for it develop stress which leads to a failure (burst). The leading cause of rock bursts in underground mining is usually the mining-triggered variation of the stress field. In most cases a rock burst has no direct relation with a blast nearby.
A large burst can be detected by a seismic system easily, while a small rock burst cannot be picked-up by a seismic system.
However the size of the burst it's occurrence is always dangerous to minners working near that location of burst.
