7112俯采综采放顶煤工作面防灭火技术实践

Practice of the Fire Prevention Technology on 7112 Underhand Mining and Fully Mechanized Mining Coal Caving Face

针对田陈煤矿7112综采放顶煤工作面全面俯采、地质条件复杂的特点,常规单一的注浆、注水、注氮、注高分子材料等防灭火措施效果不佳,通过对防灭火技术的实践,形成以注浆、插管注水、增阻升压为主的综合防灭火措施,有效的预防了自燃现象的发生,保证了工作面的安全生产。

Aimed at the full underhand mining and complex geological conditions of 7112 fully mechanized mining coal caving face in Tianchen coal mine, the effect of conventional and single injection of grout, water, nitrogen and polymer materials and other fire prevention measures is not good. Based on the practice of fire prevention technology, the integrated fire prevention measures, which were formed by grouting, tube water injection, and the increase of resistance and pressure are effectively prevent the occurrence of spontaneous combustion and ensure the safe production of the working face.
