Abstract

The article describes determination of oxidizability and spontaneous combustion of ore and rocks as a case-study of the Oktyabrsky deposit. The rate of oxidation of sulfide ore increases after watering. The authors present the studies on sensitivity of ore and enclosing rocks to spontaneous combustion, as well as on gas emission in isothermal conditions and in heating. It is found that sulfide ore, hornfels and gabbro-dolerite are sensitive to spontaneous combustion.

原生矿石和岩石以及含水矿石和岩石的氧化性和自燃性

摘要文章以奥克恰布尔斯基矿床为例，介绍了矿石和岩石氧化性和自燃性的测定方法。硫化矿石的氧化率在浇水后会增加。作者介绍了对矿石和围岩自燃敏感性以及等温条件和加热条件下气体排放的研究。研究发现，硫化矿、角闪岩和辉长岩对自燃很敏感。
