神南矿区煤炭开采水资源漏失量评价分区

Zonation of water resources leakage due to coal mining in Shennan mining area

  • 摘要: 针对神南矿区煤炭开采与水资源保护的矛盾问题,通过野外踏勘资料、钻孔资料及压水试验数据等,分析了研究区水资源分布特征、土层物质含量和渗透特征以及区内工程地质条件对保护砂层潜水所起的作用。把(导水)裂隙带、岩层厚度、土层厚度作为分区因子,根据煤层采动对浅层地下水的影响程度,将研究区划分为严重失水区、一般失水区、轻微失水区和无影响区4个区;结合地貌特征,进一步细分为梁峁漏失区、梁峁无影响区、严重失水区(砂层)、一般失水区(砂层)、轻微失水区(砂层)和风沙滩地无影响区6个区。该研究成果可为区域水环境和生态环境保护提供科学评价依据。

     

    Abstract: Aiming at the contradiction between coal mining and water resource protection in Shennan mining area, through field investigation data, borehole data and water injection data, the paper analyzed the distribution characteristics of water resources, material content characteristics of soil layer and the role of engineering geological conditions in protection of phreatic water of sand layer in the study area.Water-conducting fractured zone, thickness of formation, thickness of soil layer were taken as factors for zonation.According to the influence of mining disturbance on shallow groundwater, the study area was divided into four zones, i.e., zone of serious water leakage, zone of normal water leakage, zone of light water leakage and not influenced zone.According to geomorphologic characteristics, the study area was further divided into six zones, i.e., water leakage zone of Liangmao, not influence zone of Liangmao, zone of serious water leakage(sand layer), zone of normal water leakage(sand layer), zone of light water leakage(sand layer) and not influenced zone of shaoly land.The results of this study can provide scientific basis for protection of regional water and ecological environments.
