厚煤层放顶煤工作面采空区防火工作一直是“一通三防”的难点,采面月推进度、配风量是关键因素。文章介绍了利用束管监测系统划分采空区“三带”对合理调整采面月推进度,合理确定埋管深度、埋管步距,防治自然发火具有指导意义。 Thick coal seam caving work face gob of fire prevention work has always been “one pass three anti-difficult,” the degree of mining face months, with the amount of air is the key factor. The paper introduces that it is instructive to divide the gob area “three belts” by using the beam tube monitoring system to reasonably adjust the propulsion degree of the mining face, reasonably determine the depth of buried pipe, the length of buried pipes and prevent and control spontaneous combustion.
