对于具有自燃发火倾向的某些硫化矿床,矿石的自燃性除同含硫量有关外,还与硫化矿物组分、结构、矿体赋存条件,开采状况等因素相关。本文拟以广东、广西地区的硫铁矿为例,仅就矿物组分中含碳量与硫化矿石自燃的有关问题谈一点浅见。 根据一些矿山开采实践,硫化矿石自燃与含碳量存在密切关系:含碳量越高,自燃程度越高。例如,含煤硫铁矿含碳量往往高达10％以上,开采中极容易引起矿石自燃; For some sulphide ore deposits with spontaneous combustion tendency, the self-ignitability of ores is related to the sulfur content, the composition of sulphide minerals, the structure, the conditions of ore bodies and the conditions of exploitation. This article intends to Guangdong, Guangxi region of the pyrite, for example, only on the carbon content of mineral components and sulfide ore spontaneous talk about some humble opinion. According to some mining practice, spontaneous combustion of sulfide ores has a close relationship with carbon content: the higher the carbon content, the higher the degree of spontaneous combustion. For example, the carbon content of coal-bearing pyrite tends to be as high as 10% or more, causing extremely spontaneous ores in the mining process.
