Abstract

X-ray fluorescence analysis was used to study the composition of mineral inclusions in outburst-prone coal bed. A relationship between the presence of iron-containing compounds and sulfur in coals with their tendency to gas-dynamic phenomena was revealed. It was found that coal outbursts from the Pechora and Donets basins contained several times more iron than coals from non-hazardous zones of in the same coal bed. The predominance of iron over sulfur in outburst coal relative to a stoichiometric ratio between them in pyrite and, similarly, the predominance of sulfur content in coals from the zones of bed unprone to outbursts were determined.

化石煤中的铁和硫夹杂物及其与气动力现象的关系

摘要

用X射线荧光分析法研究了易突出煤层中矿物包裹体的组成。揭示了煤中含铁化合物和硫与气体动力学趋势之间的关系。研究发现，在同一个煤层中，从Pechora和Donets盆地喷出的煤中所含铁比在非危险区的煤高出几倍。确定了相对于黄铁矿中煤中铁相对于硫的化学计量比占优势的硫，并且类似地，确定了来自不易发生煤层的煤层中煤中的硫含量占优势。
