易自燃煤层综放面采空区自然发火预测技术分析

Analysis the spontaneous combustion prediction technique of gob in fully mechanized caving face mining spontaneous combustion coal seam

采空区冒落大,遗留的大量松散遗煤容易发生氧化反应,产生自然发火灾害,严重影响煤矿安全生产。本文结合山煤河曲上炭水煤业1203综采工作面特征,通过模拟实验方式,进行自然发火预测技术分析。

Caving region is larger in Gob; a lot of remaining loose coal is prone to oxidation,and produce spontaneous combustion disaster,seriously affecting the safe production in coal mine. This paper combined the character of 1203fully mechanized caving face of Hequ mine of Shanxi coal import and Export Group,through the simulation experiment,for spontaneous combustion prediction analysis.
