下沟矿瓦斯抽采系统仿真模拟及优化分析
Xiagou mine gas extraction system simulation and optimization analysis
摘要
Abstract
In view of the low suction pressure of gas drilling and small flow and pipeline leaking problem which are often encountered in the coal mine production,this paper took Xiagou mine as the case of study,built a mathematical physics model with the graph theory and fluid mechanics theory,and used the Cross algorithm in the gas extraction's analogue simulation.Through contrastive analysis of the gas extraction actual measured parameters and the simulation parameters,this study inferred the origin of problem in the gas extraction which provides the basis for the optimization of gas extraction system.Simulation results show that the average quantity of drilling field is 0.059 4 m3/s,the average quantity of upper corner is 0.215 8 m3/S,and 26#～30# drilling field's resistance is large.The measured results are basically consistent with the simulation results which can provide reliable results.关键词
