摘要
阳煤五矿8421工作面局部带压,已经采用无线电波透视法、矿井瞬变电磁法、直流电法对该工作面进行了综合水文物探并综合分析划分了3个底板相对富水区,运用矿井底板突水系数法对工作面带压开采综合评价后提出了回采应采取的措施,为带压开采工作面安全回采奠定了基础。
No. 8421 working face of No. 5 coal mine belongs to local water pressure mining. By using radio wave penetration method,mine transient electromagnetic method and direct current method,the comprehensive hydrological exploration was carried out,and three floor relative water rich areas were divided. Based on the floor water bursting coefficient method,comprehensive assessment of mining with water pressure was carried out,and the measures to be taken were put forward,which lays the foundation for safety production of mining face with water pressure.
