Published in 2022 at "ACS Omega"

DOI: 10.1021/acsomega.2c00339

Abstract: It is imperative to have an in-depth understanding of the gas migration mechanism during close-distance coal seam mining, not only to prevent fires in the coal industry but also to propose safety strategies for controlling… read more here.

Published in 2025 at "Scientific Reports"

DOI: 10.1038/s41598-025-24212-3

Abstract: Upward mining of close-distance coal seams is technically challenging due to the complex nature of overburden failure and the potential hazards associated with water and gas. This study assesses the feasibility of mining the 4–3… read more here.

Published in 2025 at "Scientific Reports"

DOI: 10.1038/s41598-025-26790-8

Abstract: Compared to traditional long-wall mining, the gob-side entry retaining by roof-cutting (GERRC) technology reduces the amount of entry excavation by 50%, and recovers the previously wasted coal pillar resources, which has obvious superiority in mining… read more here.

Published in 2022 at "Proceedings of the ACM on Human-Computer Interaction"

DOI: 10.1145/3549487

Abstract: Reflection is an important precursor to attitude and behavior change, but existing advice on designing for reflection in games is mixed and requires further empirical investigation. We report on the design and evaluation (n=32) of… read more here.

Published in 2020 at "Advances in Civil Engineering"

DOI: 10.1155/2020/8885849

Abstract: During the mining of the shallow-buried and close-distance multiple coal seam, the rheological failure of the surrounding weakly cemented soft rock of the roadway in the lower coal seam under the concentrated stress is very… read more here.

Published in 2017 at "Progress in Electromagnetics Research B"

DOI: 10.2528/pierb17012701

Abstract: In this paper the results of the estimated electric field associated with tortuous lightning paths at close distance (50 m to 500 m) are shown. Such results are compared with experimental data available in the… read more here.
