用砌筑防漏墙的方法防止采空区遗煤自燃

本文从理论上提出了采空区漏风通道的新概念，将其分为能自燃漏风通道、不自燃小漏风通道、不自燃大漏风通道３种。并将采空区分为“Ｕ”形漏风区、小漏风区、中漏风区与大漏风区４区。跳出了国内外学者长期沿用的三区分法，使之与采空区的实际自燃点分布更为一致。还介绍了防漏墙的设计参数与现场应用情况

Using Anti-leakage Break for Preventing the Spontaneous Combustion of Coal Left in Gob Areas

The paper theoretically puts forword a new conception of the gob area air -leakage passage, in which the leaking passages are classified into.the leaking passage capable of spontaneous combustion, the small leaking passage of no spontaneous combustion, and the large leaking passage of no spontaneous combustion with the gob area being divided into the V - shape air - leaking area, the small air-leaking area, the medium air-leaking area,and the great air -leaking area.Design parameters of the air -leakage break and the field applications are also provided.
