| 摘 要： | 本文以水口山、宝山、锡矿山、洪水坪、湘潭锰矿等各矿区的实际资料为依据,从影响矿坑涌水量计算的诸因素中,提出了矿坑涌水量全年中出现次数最多的值作为涌水量的基准值的概念,并以此值大小把矿坑涌水量分为3大类7亚类;对涌水量的动态变化采用涌水量最大值与正常值之比作为不稳定系数来表达,并将其分为4类;据动静储量的比例系数值把矿坑水储量分为静型、静动型和动型3类,从而确定了涌水量计算的内容,对计算精度依照基准值分类各划分了四个等级和相对应的储量等级,同时确定了相应的误差值与评分标准。

| Abstract: | Based on the practical data from Shuikousha, Xikuangsha, Hongshuiping, Xiangtanmeng-kuang and other mines, according to the factors influencing the calculation of pit water yield, a concept that the most frequent value in a year is taken as the datum value of pit water yield has been proposed, and according to this value, the pit water yield is divided into 3 types and 7 subtypes. The dynamic variation of water yield is expressed by the insta-bility coefficient, the ratio of the maximal water yield to the normal value, and is classified into 4 types. According to the proportion coefficient value of dynamic and static reserves, the pit water reserve is classified into 3 types, that is, static type, static-dynamic type and dynamic type. Therefore, the content of pit water yield calculation is defined. The precision of the calculation results is classified into 4 levels and corresponding reserve classes for each datum value-based type, at the same time, the relevant error value and ranking stantard are defined. |
