    A General Review onLongwall Mining Induced Fractures in

    It is believed that undergroundlongwall miningusually produces fractures in the surrounding rocks. On the one hand,mining-induced fractures not only degrade the strength of the rock mass but also serve as main channels for fluids (e.g., water and methane). Fractures facilitate the failure of the rock mass and fluid inrush into working spaces.
