摘　　要：介绍一种火区下采矿的方法。根据易燃矿石的性质，选配出适用的阻化剂──石灰，将其制成阻化液泵入火区灭火阵温，然后用铺设钢筋混凝土假底的下向进路式水砂充填法采矿。这种方法安全、经济，有重大的推广价值。In this paper,a mining method under fire area ls briefly in-troduced. According to the properties of inflammable ores, an applicable in-hibitor-lime is made into an inhibitory solution,which is pumped into fire area,so as to put out a fire and lower the temperature. Then the ore is mined with a false reinforced concrete bottom downward drift sand filling method. This method is safe,economic and valuable for popularization.
