Numerical Simulation on the Division of Horizontal Three Straps Influenced by Nitrogen Injection Technology

摘要：

When nitrogen injection to the gob with buried pipes is used to prevent the left coal oxidizing and self - igniting, flow field characteristics are simulated by Fluent under the condition of nitrogen injection.The oxygen and nitrogen concentration with nitrogen injection or without nitrogen injection is analyzed, respectively.And it is shown how the division of horizontal three straps is influenced by nitrogen injection.Meanwhile, it can provide support to ensure the nitrogen injection parameters and improve the effect of nitrogen injection.And provide guidance to reduce the hazard of the left coal oxidizing and self - igniting.
