| 摘 要： | 通过对乌达煤田Ⅷ2C火区自燃形成条件及过程进行观测和理论分析,得出了煤矿导火带形成的条件。当煤矿导火带高度大于采空区深度、遗煤带厚度大于0.4 m、供风输氧量大于煤层燃烧最小需要量、煤体温度高于自燃点、排烟能力大于煤层燃烧的最大产烟量时产生煤田地面火区,并对这一结论在乌达煤田Ⅲ和Ⅷ火区的10个燃烧带进行了验证。

| Abstract: | The Conditions forming combustion zone are obtained by measuring and analysting coal spontaneous combustion conditions in Wuda mine field Ⅷ2C fire field.Those conditions include that combustion zone is higher than goaf,the thickness of coal in goaf is more than 0.4m,the providing O2 is more than need,the coal temperature is higher than need and the smoke emission ability is more than coal spontaneous combustion generating.And the conclusions are proved in ten combustion zones in Wuda coal field Ⅲ and Ⅷ fire field. |
