| 摘 要： | 用有限元数值模拟方法结合图形显示技术,对铁法小青矿 S_2403采空区瓦斯抽放问题进行了分析,模拟了采空区瓦斯分布、回风隅角瓦斯聚积以及瓦斯抽放的流体力学原理,重点探讨了利用数值模拟方法解决抽放流量的合理确定问题:抽放瓦斯可降低通风强度,并能控制采空区瓦斯向工作面涌出;理论上还可进一步改进抽放工艺为单纯埋管抽放方式,适当提高抽放流量,以达到安全、经济的目的。

| Abstract: | With the method of limited metadata simulation and graphics displaying technique,we analyse the inflate and deflate of the gas flux of S2 403 Xiaoqing mine,and simulate the gas distribution in the excavated area,the assemble of corner's gas,the hydrodynamics principle.We lay the emphases on the discussion for the confirmation of the way in which we could solve the inflation and deflation of reasonable gas flux with the method of numerical simulation.The gas is drawn and coal is deflated and ventilation is easy,and the gas of excavated area is controlledm technology of drainage is improved and rate.Furthermore,safety and economical purpose are realized. |

| Keywords: | excavated area draw deflate gas drawing and deflating flux numerical simulation |
