Study on model of top-coal arch structure simulation

摘要：

　　According to analysis and field observation on influencing factors of the drawing, arch structure is formed due to the fractured top coal extrude mutually.Top coal drawing is a process that arch structure is formed and damaged periodically.Based on ellipsoidal draw theory, natural equilibrium arch and parabola model, arch structure model for top coal drawing has been established.The model is verified by engineering practice.
