| 摘 要： | 孤岛综放面在正常回采期间,四周均是采空区,具有复杂的多源多汇漏风通道,采空区后自燃"三带"的确定对防灭火具有重要的意义。根据孤岛综放面采空区的特点,分别通过现场实测和采用FLUENT软件数值模拟的方法,判定实际条件下运河矿1302孤岛综放面"三带"分布规律,为孤岛综放面自燃火灾的防治提供理论依据。

| Abstract: | Due to goaf around,isolated island caving workface possesses complex multi-source and multi-channel exchange of air leakage during normal mining period.So the identification of "three zones" of coal spontaneous combustion in gob has important significance for mine fire control.In this paper,based on fully mechanized caving face isolated island caving workface goaf characteristics,using field measurement and numerical simulation approach by FLUENT software,"three zones" distribution of Yunhe coal mine 1302 workface is determined under the actual condition.This work provides a theoretical basis for prevention and control of coal spontaneous combustion in isolated island caving workface. |
