The mechanism of excavation-induced rockbursts in ultra-thick soft-hard composite coal seams at shallow depths: an experimental study

Gaoang Wang, Sitao Zhu, Fuxing Jiang, Jinhai Liu et al. • Geomechanics and Geophysics for Geo-Energy and Geo-Resources (2026)

Abstract Ultra-thick soft-hard (UTSH) composite coal seams, composed of alternating layers of soft and hard coal, frequently experience severe rockburst accidents during roadway excavation under shallow burial depths (...

Study on safety of a high earth-core rockfill dam considering contact effect between dam and foundation

LI Guoying, HAN Chaojun, WEI Kuangmin, MI Zhankuan • Shuili Shuiyun Gongcheng Xuebao (2019)

With a traditional method to calculate the stress and deformation of earth-rock dam, the contact effect between the dam and the bedrock is neglected, which is not consistent with the actual condition. The contact friction has a significant ...
