小浪底水库蓄水运行对矿井水害防治的影响评价

Evaluation of influence of impounding and operation of Xiaolangdi Reservoir on prevention of mining water hazards

新安煤矿系我国大水矿区,地下水害严重威胁着矿井的安全生产。本文根据大量原始资料,运用灰色系统理论和风险分析理论,讨论了小浪底水库蓄水运行对新安煤矿水害防治所造成的影响,明确指出水库蓄水后矿井突水威胁主要来自断层水及石炭系太原群L7～8岩溶水;煤矿防治水的重点应该是治理L7～8灰岩及矿区边界断层在库区的露头或隐伏露头。

Xinan coal mine in Henan Province was a mine in China with abundant groundwater and faced threat of water\|filling tunnels in mine. On basis of a variety of original data and according to grey system theory and risk analysis theory, the influence of impounding and operation of Xiaolangdi Reservoir on prevention of water hazards in Xinan coal mine was discussed. Threat of water\|bursting in mine mainly comes from water occurring near faults and L7-8 limestone water\|bearing stratum of Carboniferous age after impounding of reservoir.Focus of provention of water hazards in the coal mine is on the control of the outcrop of the L7-8 limestone and the boundary faults occurring in the reservoir area.
