元氏煤矿下组煤开采的可行性及防治水措施的探讨

在分析区域及井田水文地质条件基础上,通过对井下岩层含水性的和防治水措施的研究,提出了在现有条件下加强对井下水的治理,加强防、探、固、堵、隔、研的防治水方针执行,降低奥灰水对煤层开采威胁,实现带压开采,减少突水造成淹井的影响.结合现有勘探资料基础,就下组煤开采可行性及其安全开采防治水措施进行初步讨论,并提出建议和措施.

Discussion on the Feasibility of Under Coal Group Mining and the Underground Water Control Measures

In the analysis of regional and Minefield hydrological and geological conditions on the basis of water through underground rock, and water control measures of the study, proposed to strengthen the existing conditions of the underground water governance, strengthen the prevention, detection, solid, block, separated from policy implementationresearch prevention and treatment of water, gray water to reduce Austrian threat of coal mining, mining achieve with pressure to reduce the sudden impact of water caused bysubmergence. Combined with the existing exploration data base, the feasibility of coal miningon the next set of water control measures and safe mining preliminary discussions, and recommendations and measures. 5refs.
