    Numerical simulation of fracture evolution behaviors in deep roadway surrounding rock containing discontinuous joints by Chengjun Hu, Gang Song, Jiyu Wang, Baofu Zhao, Zhengya Tao, Fan Wen, Bo Meng

    Published 2025-01-01
    “…To explore the internal bearing characteristics and fracture evolution laws of discontinuous jointed rock mass in deep roadways, the −600 m main roadway in Xin ’an Coal Mine was used as the research background. The fracture fractal dimension D was employed to characterize the joint density, and an intermittent jointed roadway model, both without support and with anchor cable support, was modeled using the particle flow software PFC2D. …”

    Impact of new coalbed methane wells on old well productivity and its controlling factors: a case study of Shizhuangnan block in Qinshui Basin by Xueting HAN, Shangzhi MENG, Guangjing LIU, Zhenyu REN, Shu TAO, Xinyang MEN, Ziyang WEI

    Published 2025-01-01
    “…To address the issue of uneven productivity release in the Shizhuangnan block of the Qinshui Basin, the initial well pattern is optimized through horizontal well infill to enhance reservoir utilization. However, frequent occurrences of drilling mud and fracturing fluid migration to neighboring wells have resulted in varying degrees of effect to old well productivity. …”
