为防止采空区因漏风而导致遗煤自燃,经计算机模拟与现场实施研究,定期在采空区“U”形漏风带构筑隔漏风墙,能明显地造成采空区内漏风量及漏风范围跳跃式骤减,扩大不自燃区范围,有效地杜绝了采空区遗煤自燃与瓦斯爆炸灾害.经六枝矿务局木岗矿两年多实施,减少灾害经济损失300多万元.该措施还具有施工简便、成本较低等特点,很适合于经济较不发达、井下条件复杂的突出易燃矿井应用.
In order to prevent goaf spontaneous combustion due to air leakage, computer simulation and on-site study conducted regularly to construct a leaking wind wall in the “U” -shaped air leakage zone in the goaf, which can obviously cause air leakage and air leakage in the goaf Leaps and bounds, expand the scope of non-spontaneous combustion zone, effectively eliminate spontaneous combustion of coal leftovers and gas explosion disaster. After more than two years of operation by Mogang Mine of Liuzhi Mining Bureau, the economic loss of disasters was reduced by more than 3 million yuan. The measures also have the characteristics of simple construction and low cost, and are suitable for the application of the prominent flammable mines with less developed economy and complicated underground conditions.
