特殊环境下防灭火技术的应用

Under the special environment of application of fire prevention and control technology

河南大有能源股份有限公司常村煤矿位于河南省义马市东南,主采煤层为侏罗系中统下段义马组煤田,地质构造简单,为典型的长焰煤易自燃煤层。在回采过程中综放工作面的直接顶中有一老巷与采空区串通,造成工作面采空区漏风,致使上隅角CO浓度很高,采取防灭火技术措施,有效控制了该工作面采空区CO浓度,使回采工作顺利进行,实现了矿井的安全生产。

Henan great energy Limited by Share Ltd of Changcun Coal Mine in Henan province is located in the southeast of the city of Yima, the main coal seam in the Jurassic system in Yima coalfield geological section group, simple structure, is a typical long flame coal spontaneous combustion seam. in the process of mining of fully mechanized caving face of immediate roof in a lane with old goal coIIu^ion, resulting in the working face gob air leakage, resulting in up corner CO concentration is high, take prevention and control measures, effective control of the working face goal CO concentration, so that the wore carried out smoothly, achieve the mine production safety.
