The Rock Burst phenomenon is not strictly a deep mine problem. The real cause is high in situ stress. This can occur in shallow mines where the host rock is naturally highly stressed due to tectonic forces. Shallow mines with advanced extraction (high extraction ratio) may also be rock burst prone due to natural redistribution and concentration of ground stresses in remnant or abutment pillars.

Feel free to be bold and improve the article.--Commander Keane (talk) 11:00, 19 June 2010 (UTC)[reply]

I went ahead and made this change. --Djachambers (talk) 18:09, 5 April 2019 (UTC)[reply]

Under Pressure

At present, the article summary states,

... Although mines may experience many mining-related seismic events, only the tremors associated with damage to accessible mine workings are classified as rock bursts. The opening of a mine workings relieves neighboring rocks of tremendous pressure, which can literally cause the rock to explode, or trigger abrupt movement on nearby geological structures. Rock bursts are a serious hazard; ...

I am not a miner, nor do I have much education in the area of outbursts, but it seems to me that as the mine is worked, supporting material along the face of the mine is removed, introducing instability and precipitating an outburst where rocks fissure and explode with surprising force. The present wording of "relieves neighboring rocks of tremendous pressure" seems to suggest working the mine alleviates the problem instead of causes it. Wouldn't it be better to say "relieves neighboring rocks of support needed to counteract the tremendous pressure"?

I would make the change, but given my lack of education on the subject, I am not feeling as bold as Commander Keane has exhorted. I will look into the subject. In the meantime, someone else more knowledgeable is invited to weigh in. --Srwalden (talk) 21:19, 29 March 2019 (UTC)[reply]

Yes I agree, your proposed change is more clear and correct Djachambers (talk) 18:08, 5 April 2019 (UTC)[reply]
