| Abstract: | In order to study the law of gas migration in the roadway of fully-mechanized working face，and find out the state of gas flow，a combination of theoretical analysis，numerical simulation and field test was used to obtain the airflow characteristics and gas migration law of the working face.Through theoretical analysis，the gas concentration distribution changes on the working face and the normal working gas concentration distribution on the working face were obtained.After the gas is released abnormally，and then the field test was carried out.The test results are similar to the numerical simulation results.The research provides technical support for gas control in working face. |
