Sensor Deployment Optimization Based on Simulation of Gas Distribution in underground Fully Mechanized Coal Face
The gas sensor is very important for coalmine production safety.The Fluent software was used to simulate underground gas distribution.Geometry model was established and divided by grids.Gas distribution in fully mechanized coal face was simulated using RNG k-ε model according to conversation equation in turbulent state,turbulent kinetic energy equation and turbulent dissipation rate equation.The results show that gas is likely to accumulate in the upper comer,when wind passes through the comer after washing fully mechanized coal face,wind velocity is unstable,performance of sensor placed in inner side of turning is different from that placed in outer side of turning.The result shows that gas can be monitored effectively with this method which has an important value and instructive significance.
