本文主要阐述用注水方法防止煤矿井下自然发火。并系统介绍了矿井注水防火实例。如,辽宁烟台煤矿、陕西崔家沟煤矿、山西阳方口煤矿、汾西局水浴矿和轩岗局焦家寨矿、六亩地矿。上述煤矿对有自燃倾向的厚煤层开采时,普遍采用了采空区注水,均取得良好防火效果。 This article describes the use of water injection method to prevent coal mine natural fire. An example of mine water injection and fire prevention was introduced systematically. For example, Liaoning Yantai Coal Mine, Shaanxi Cuijiagou coal mine, coal mine in Shanxi Yang Fangkou, Fenxi West Lake water bath and Jiaojiazhai Coal Mine, six acres of land and mineral. When the above coal mines exploit the thick coal seam with the spontaneous combustion tendency, the water injection in the goaf is generally adopted, and the good fire prevention effect is achieved.
