| Abstract: | Based on underground dust measurement, the dust-laden airflow in long wall coal face is taken as 3-dimensional steady turbulent gas-particulate flow. A mathematical model is set up and the differential equation is solved by numerical solution of finite volume method. A 3D/2P computer program is developed successfully. An example of dust distribution is studied, which concludes that the dust should be controlled at the dust source. The computer program can be used to evaluate the dust control measures. |
