| Abstract: | By use of the experiment of bundle tube monitoring on site,the characteristics of fully mechanized sublevel caving mining goaf were analyzed and summarized.Based on the principle of computational fluid dynamics and numerical simulation software FLUENT,the oxygen concentration field,i.e.the key delimiting index of oxidation zone and suffocative zone,was simulated for the different characteristics of fully mechanized sublevel caving mining goaf.The simulation results were compared with experimental results.
