| 摘 要： | 本文采用水力学模型实验方法,模拟了U.W.Z.Y和H型工作面通风方式的采空区渗滤流场。提出了与采空区遗煤自燃的相关参数为采空区易燃风速带的最大宽度D_(max),实验得出了W型通风方式D_(max)最小,这与计算机模拟的结果一致。因此,从预防采空区遗煤自燃方面采说,W型通风方式优于其它几种通风方式。

| Abstract: | This paper introduces that the hydro- modeling tests similate the air filtration process in goaf with different face ventlation systems. U.W.Z.Y and H face ventilation havebeen modelled. The parameter relevant to coal spontaneous combustion has been proposed. That is the maxmum width of risky velocity zone of coal spontaneous combustion(Dmax). The tests show that Dmax of W ventilation is the shortest and the same result is also obtained by using the computer modelling method. From the viewpoint of preventing coal spontaneous combustion is goaf, therefore, W ventrlation is better than the others. |
