新安矿二1煤底板突水性评价及防治建议
Possibility Analysis and Suggestion of Prevention and Cure on Ordovician Limestone Water-bursting of First Coal Seam of Group Two in Xin’an Coal Mine
【摘要】 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。
【Abstract】 Xin’an Coal Mine in Henan Province is a mine in China with abundant groundwater and faced threat of water-filling tunnels in mine.According to the geology and the hydrology geologic structure characteristic of Xin’an coalfield,the condition of water filling to the coalfield is analyzed,the influence of ordovician limestone water to the risk of water-bursting from soleplate are madeclear.The preventing and controlling water suggested is pointed out.The reference function to the coal mine is anticipated.
