Mechanism and Control of Deformation and Failure of Mining Roadway in Thick Coal Seams Under Close Range Goaf

Energy Science &Engineering, EarlyView.
ABSTRACT In response to the problems of asymmetric deformation and failure caused by the close range and thick coal seam fully mechanized caving roadway, as well as the difficulty in ensuring the control effect of the roadway surrounding rock. Through numerical simulation and on‐site industrial experiments, combined with the geological conditions of a

Hydrocarbon Potential of the Pabdeh Formation: Geochemical Insights Into Immature Source Rock Capabilities

Energy Science &Engineering, EarlyView.
ABSTRACT The Pabdeh Formation (Paleocene‐Oligocene) is one of the hydrocarbon‐generating formations in the Zagros sedimentary basin. In this study, to evaluate its hydrocarbon potential and the distribution of organic matter maturity, samples were collected from oil fields in southwestern Iran and the Dezful embayment and analyzed geochemically.
