上庄煤矿水文地质特征及主要充水因素分析

Analysis of hydrogeological characteristics and main water filling factors in Shangzhuang Mine

矿井水文地质条件是评判煤矿安全开采的重要标准之一,主要充水因素是矿井水防治的主要依据。根据上庄煤矿地质、物探及钻井资料,综合分析了井田水文地质特征及主要充水因素,阐明了3号煤层采空区积水及K8砂岩富水区分布特征,揭示了以导水裂隙为主要充水通道的各煤层开采潜在风险,为矿井安全生产及矿井水防治提供了依据。

Mine hydrology and geological conditions are one of the most important criteria for judging the safety of mining,and the main water-filling factors are the main basis for mine water control.Based on the geological,physical exploration and drilling data of Shangzhuang Mine,the hydrological and geological characteristics as well as the main water-filling factors of the mine were analyzed comprehensively,and the characteristics of the water accumulation in the goaf of the No.3 coal seam and the distribution of the water-rich area of the K8 sandstone were clarified,the technology revealed the potential risk of each coal seam mining with water-conducting fissure as the main water-filling channel,which provided the basis for mine safety production and mine water prevention.
