摘 要: | 根据分形理论建立煤层露头火区裂隙的面密度分维、露头火区煤岩体孔结构分维及块度分维计算模型,现场观测研究煤层露头火区剖面面密度分维,并根据压泵实验结果研究了煤岩样的孔结构分维,与块度分维计算结果进行了比较。对于更进一步研究煤层露头火区氧气输运、逾渗规律、露头火灾机理具有积极意义。

Fractal Structure of Pores and Splits of Coal Combusted Outcrop |
| |
Abstract: | On the basis of fractal theory,the fractal dimension models of surface,volume and block are put out.Fractal dimension of surface density is researched by mea-suring the coal outcrop section of Wuhu Mountain.Furthermore,coal rock is strdied by the pore structre testing.The results is useful to carry out the re-search on the combustion mechanism in coal outcrop. |
