Research on the distributing law of the gas in the gob area based on flow-tube model

摘要

Based on network solution, the gob area wind Meld in air leak distribution is derived. Then stream-tube model and conservation equation between stream-tube gas volume and composition are established. Air leak field is analyzed and streamline is drawn by matlab2007a. According to gas concentration data of the monitored finite points, gob area concentration field can be simulated to get the gob gas distribution.
