高瓦斯矿井过构造期间综合防灭火技术

Comprehensive Fire Prevention and Extinguishing Technology during Over Construction of High Gas Mine

阳煤集团二矿属高瓦斯矿井,部分区域存在自燃倾向性,在受到断层、陷落柱等地质构造等因素的影响的非正常回采期间,工作面推进速度缓慢,采空区具有自燃发火隐患的发生。因此,为避免工作面过构造期间采空区自燃发火,保证81001工作面过构造期间回采作业安全,通过控风均压、灌注凝胶以及注三相泡沫技术相结合的方法,对采空区进行综合治理,实现过构造期间采空区防灭火的目的。

The second coal mine of Yangquan coal （group） company is a high-gas mine, with spontaneous combustion tendency in some areas. During abnormal mining affected by the geological structure such as faults and collapsing columns, the working face advancing slowly, and the goaf possesses spontaneous combustion potential occur. Therefore, in order to avoid spontaneous combustion in the goaf during the construction period of the working face and to ensure the safety of 81001 working face during the operation of the mining operation through the combination of controlled wind pressure, gel impregnation and three-phase foam injection technology,carry out comprehensive management and achieve the purpose of preventing and extinguishing fire during the construction of the goal.
