| 摘 要： | 针对煤矿井下采掘空间中瓦斯扩散问题,通过理论分析建立了井下风流中瓦斯扩散的数学物理模型,并利用数理方法得到模型的解析解,解决了煤矿井下采掘空间瓦斯扩散的浓度分布问题,并与现场考察的结果相互比较,结果表明,所建立的井下风流中瓦斯扩散模型能较好地反映瓦斯的实际扩散过程。 |

Research on Diffusion Model of Gas Emission in Mine Air Current |
|
| Abstract: | To counter the diffusion problem of gas emission in the mining space in a coal mine,a math-physical model of gas emission diffusion in mine air current was established through theoretical analysis.The analytical solution of the model was obtained by mathematical method,which solved the concentration distribution problem of gas emission in the mining space in the coal mine.The comparison with the result obtained in the field study showed that the established gas diffusion model can better reflect the actual gas diffusion process. |
