Environmental Policy and Governance, EarlyView.ABSTRACT The role of civil society organizations (CSOs) in addressing climate change is acknowledged, but engagement with questions of voice remains limited, especially in the Global South. Addressing this, this paper zooms in on (International) nongovernmental organizations ((I)NGOs) and their collaborations with domestic CSOs in the Global South on ...

Energy Science &Engineering, EarlyView.A stress wave propagation model for coal‐rock combinations under in situ stress was established. Taking a coal mine in Huainan, China as the engineering background, isotropic and anisotropic numerical models were constructed. Field engineering practices were carried out to verify the reliability of the conclusions.

Energy Science &Engineering, EarlyView.One‐way FLAC3D‐COMSOL coupled modeling and field validation show that a 150 mm borehole radius with 5 m spacing provides the best coordination of plastic‐zone expansion, stress relief, permeability enhancement, and gas‐pressure attenuation, increasing the pure gas drainage rate by 35.4%. ABSTRACT To rationally determine the borehole radius and borehole
