福兴煤矿现开采的急倾斜煤层多采用伪倾斜柔性掩护支架采煤法，由于前期开采经验不足，工作面搬家频繁，采空区多次出现自燃征兆，安全生产形势较为严峻。通过近几年的不断探索和总结，制定了有效的安全防范技术措施，从而大大降低了煤层自然发火几率，确保了矿井安全生产。

Fuxing coal use the false inclined lfexible shield mining method in mining steeply inclined coal seam, due to the lack of experience of working face mining, frequent moving, occurred repeatedly the signs of coal spontaneous combustion in gob, production safety situation is more severe, in recent years through the continuous exploration and summary, developed the security and effective technical measures, which greatly reduces the risk of spontaneous combustion of coal, and ensures the safety of mine production.
