Study on the mining response law and coal burst risk assessment of an isolated working face

Autor: Guojun Liu, Ruide Lei, Ling Huang, Menglai Li, Jiankun Zhou

Publikováno v: Frontiers in Earth Science, Vol 12 (2024)

With the increasing demand for coal resources and the unreasonable arrangement of subsequent working faces, mining activities in isolated working faces are more likely to induce coal burst accidents. In this study, the minimum distance principle is u

Study on the adsorption of CH4, CO2 and various CH4/CO2 mixture gases on shale

Autor: Xidong Du, Yugang Cheng, Zhenjian Liu, Zhenkun Hou, Tengfei Wu, Ruide Lei, Couxian Shu

Publikováno v: Alexandria Engineering Journal, Vol 59, Iss 6, Pp 5165-5178 (2020)

The isothermal sorption experiments of CH4, CO2 and CH4/CO2 mixture gases on shale were performed. The sorption affinities of CH4, CO2 and CH4/CO2 mixture gases were compared using Henry’s coefficient (KH). The thermodynamics of sorption of CH4, CO
