河南新安矿区煤层底板突水评价及防治建议

Possibility Analysis and Suggestion on Ordovician Limestone Water-bursting to Xin'an Coal Mine in Henan Province

新安矿系我国大水矿区,煤矿水害严重威胁矿井安全生产。根据河南省新安矿区地质及水文地质构造特征,对矿区煤矿床充水条件分析,明确奥灰水对底板突水危险性影响,并提出防治水建议,期待能对矿区煤矿生产起到参考的作用。

Xin＇an coal mine in Henan Province was a mine with abundant groundwater and faced threat of water-filling tunnels in China.According to the geology and the hydrology geologic structure characteristic of Xinan coalfield,analysis condition of water filling to the coalfield,is clear about influence of Ordovician limestone water to the risk of water-bursting from soleplate,and proposed the preventing and controlling water suggested,anticipated can produce the reference function to the coal mine.
