多单元多步骤阶段矿房采矿法防硫化矿尘爆炸措施的探讨

硫化矿床开采过程中，矿石与空气接触，氧化产生高温，易引发自燃、火灾、爆炸等事故，尤其是在使用阶段矿房采矿法过程中，矿石损失率较高，损失矿石滞留采空区相对时间较长、易氧化，如何防范和控制硫化矿石氧化是个难题．江铜集团东同矿业有限责任公司是一个有近50年井下开采铜硫矿体的矿山，在推广使用阶段矿房采矿法过程中，通过优化采区单元结构参数、实施采区现场的温度监测、缩短采区回采周期等方面进行了有益探索，取得了较好效果．

Discussion on Anti-sulfuration Dust Explosion Measurement in Multicell and Multi-process Phase Mining

In the process of sulfuration bed mining, high temperature often cames into being from oxidation owing to the combination of ore and air, which will cause spontaneous combustion, fires or explosion.How to keep away the oxidation of sulfuration ores is a problem. With a history of SO years, Dongtong Mining Co. Ltd. has achieved a lot in extending phase mining, optimizing mining sections＇ cell frame parameter, actualizing temperature inspection of mining spot and shortening stoping period.
