中文摘要:
      利用渗流基本原理,推导得出榆神矿区煤炭开采对水资源的影响系数计算公式,提出影响程度分区方法及标准。通过对区内钻孔资料统计分析,计算得到528个影响系数,结合水文地质条件,将榆神矿区煤炭开采对水资源影响程度划分为无水采煤区、间接影响区、直接影响区3大类,并进一步划分成数个亚区,其面积分别为836、3 668、761 km2,占矿区总面积的15.88%、69.67%、14.45%。对比研究区及周边矿井涌水量实测数据,涌水量较大井田位置与本次分区结果一致,分区方法及标准正确可行,对水文地质条件相似区域具有借鉴意义。最后,根据典型煤矿排水特征及对水资源的影响,提出煤炭开采的水资源保护建议。
英文摘要:
      Based on the principle of seepage, the formula of the influence coefficient of coal mining on water resource in Yushen Mining Area was derived, and the zoning methods and criteria for impact levels were proposed. Through statistical analysis of drilling data, 528 influence coefficients were calculated. Considering the hydrogeological conditions, the impact levels of coal mining on water resources in YuShen Mining Area was divided into three categories: no water area, indirect impact area and direct impact area, with an area of 836 km2, 3668 km2 and 761 km2 respectively, accounting for 15.88%, 69.67% and 14.45% of the total mining area. Furtherly, they were divided into several subareas. According to the measured data of inrush water, the location of the high water yield mines is consistent with the results of this zoning, which proves that the zoning methods and standards are correct and feasible, and they can be used in areas with similar hydrogeological conditions. Finally, based on the drainage characteristics of typical coal mine and the influences on water resource, several suggestions on water resource protection for coal mining were proposed.
