摘要
粉煤灰、胶凝剂具有渗透性和膨胀性,可应用于矿井通风工程的各种密闭、矿井下巷道的气体堵漏和漏煤眼的封闭中。介绍了在通风工程中利用粉煤灰胶凝剂作为封堵材料的方法等。
The fly ash and the rubber gel has the permeability and expansion, its application in mine ventilation engineering of the various airtight and mine roadway gas leaks and leakage of leakage of coal eyes closed. The method that by using fly ash gelling agent as sealing materials in the mine ventilation are introduced.
