摘要: 凤凰山矿采用Y型通风沿空留巷无煤柱开采,漏风规律复杂、漏风量大,属于自燃煤层,为了对煤炭自燃发火提前预测预报,采用自行研制的“煤自燃特性综合测试系统”进行试验研究,得到15#煤自燃以CO为主、C2H4和C2H2为辅的标志性气体体系,取得较好的效果。

Abstract: According to the Phoenix mine Y type ventilation gobside entry retaining mining without coal pillar, a large quantity of air leakage, the rules of air leakage complicated, and spontaneous combustion of coal.In order to prediction of coal spontaneous combustion earlily, the selfdesigned “coal spontaneous combustion characteristic test system” is adopted to so some related research.The research results show that the mark gas system is acquired,an achieve a goo effect. It is necessary to explain that, the gas system contain CO of the 15# spontaneous combustion of coal,which is the main ingredients of the gas system,and C2H4 and C2H2,which are the less content of the gas system comparing with the CO.
