2026-02-05 Gas Data for the Excavation Face at Dongpang Mine, Jizhong Energy Group doi:10.57760/sciencedb.36619 en Data was collected from the tunneling face at Dongpang Mine, Jizhong Energy Group. The mine employs the KJ90 safety monitoring system, which ensures reliable data transmission. Methane concentration data is obtained via the KG9701A methane sensor installed in the belt tunnel. Its key technical parameters include: measurement range of 0.00%-4.00% CH₄ and measurement accuracy of ±0.20% CH₄. Additionally, the dataset incorporates daily tunneling progress and ventilation volume. gas; Coal mine; Security Monitoring Zou Peizhe RESTRICTED dataset Science Data Bank
