摘要
现已查明,并非含硫量高的矿床都能发生矿石自燃火灾。而只是含铁硫化物的矿床,并经历了预氧化过程的矿床,才具有发生自燃火灾的危险性。这一结论是经过长期研究和总结长期生产实践得到的。本文依据上述结论探讨自燃性硫化矿床的有效开采,并通过对典型矿山的自燃内因火灾的分析,阐明开采自燃性硫化矿床时应遵循的原则.
It is known that not all deposits with high sulfur content will pose spontaneous combustion hazards. It will be the case only with ferrous sulfides deposits which have undergone pre-oxidation, as concluded from the long-term study and mining practice. Based on this conclusion, the effective mining methods for such dangerous sulfides deposits are discussed. A case study on spontaneous combustion disasters from sulfides ore ignition has suggested some rules to follow for such deposits mining.
