潘三矿回采工作面自然发火规律及“三带”划分研究

Study on Spontaneous Combustion and “Three Zones” Division for Mining Face in Pansan Coal Mine

为了掌握1761(3)综采工作面自然发火严重程度,采集了工作面煤样,进行了氧化升温实验。测定了各煤样氧化升温的热力学特性参数和氧化升温过程中的气体产物,提出了各煤样的自然发火的标志性气体。从理论和现场观察两方面分析了工作面自然发火的“三带”范围。研究了工作面的自然发火规律,提出了工作面的防火措施。

In order to control spontaneous combustion in 1763（3） fully mechanized coal face, coal samples were colleted, and experiment of heating-up and oxidation was done. Thermal character parameter of varied coal samples and gaseous products in the process of Oxidation Temperature rise were determined. The key gases which were generated in the process of spontaneous combustion were put forward. ＂Three zones＂ range of spontaneous combustion in coal face was analyzed according to theory and spot observation. Spontaneous combustion rule was researched, and fireproofing measure was put forward.
