摘要：Gas drainage from seam is the main technical measure to prevent and control gas accident. The mathematical model and the numerical analysis method can be used to study the gas flow, and the more accurate results can be achieved. The LB method is a simplified computational model based on the microscopic scale and can be used for solving the problem of gas seepage. This paper based on LB method, simulated the gas pressure, flow track and speed vector diagram in terms of the topic for cleat coal gas drainage through symmetrical holes. It analyzed the depth of the holes influence the gas leakage; summarized and concluded the drainage performance under the controllable subjective factors during the cleat coal gas drainage process.
