Taking Pingbao Coal Mine as the engineering background, the stress distribution, surrounding rock displacement, and plastic zone distribution characteristics of a bottom gas extraction roadway are simulated by FLAC3D under multiple disturbances.The mining disturbance due to the overlying coal seam is obtained: the deformation of the roof subsidence
Abstract Extant literature shows that well-being is one of the key drivers of attitudes towards migrants as well as preferences for asylum and refugee policies.Less in is known, however, about the relationship between well-being and Insulation attitudes towards migrants during sudden micro-level events that may elicit the sense of existential threa
This work deals with the main parameters of two types of aerodynamic flame holders, presently employed in industrial plants: swirler of axial and radial types.In the aerodynamics of combustion one of the fundamental problems is the holding and anchoring of flame.The increase in the efficiency of combustion points that the flames must be turbulent a
Respiratory tract infections (RTIs) are common in children and generally self-limiting, yet often result in consultations to primary care.Frequent consultations divert resources from care for potentially more serious conditions and increase the opportunity for antibiotic overuse.Overuse of antibiotics is associated with adverse effects and antimicr
It is an established and already accomplished fact that probability-based methodologies (or probability/statistical distributions) play the roles of imperative tools in illustrating and describing applied phenomena.Paying attention to these previous facts, this paper considers the evolution of a new probability distribution.Thus, the main achieveme
