The prevention of rockbursts in Gardanne colliery

, 1995
The Gardanne colliery lies between Aix-en-Provence and Marseille and is part of the south-east complex of H.B.C.M. (Subsidiary of the Charbonnages de France group). The coal deposit is from fluvio-lacustral origin and was formed some 75 millions years ago.

Analysis of the Impact of Geological Factors on the Distribution of Abutment Pressure in Deep‐Buried Longwall Faces

Geofluids, Volume 2025, Issue 1, 2025.
To investigate the control factors of mine disasters induced by high ground pressure, this paper takes a longwall face of Pingdingshan No. 10 coal mine as the engineering background. By employing the analytical model and numerical simulation methods, this study quantified the movement characteristics of the hard roof strata and the evolution of mining ...
