kuongehLJong konton le一x一ng矿床勘探类型(exploratory‘ypes Of Ore de-Po斌s)矿床按勘探的难易程度分类。它是确定矿床勘探程度、选择勘探方法和技术手段、确定勘探工程间距和决定储量级别比例的地质依据划分矿床勘探类型的依据是:矿体规模大小,矿体形状产状变化的复杂程度,工业矿化的连续性,矿石中有用组分分布的均匀程度和构造对矿体的破坏程度。矿床中矿体规模愈大、形态产状愈稳定、矿化愈连续、有用组分分布愈均匀、构造破坏愈少(或无)的,勘探类型愈高(l或皿类);相反,则勘探类型愈低(IV、V类);各种变化指标中等,则属中等级别类型(班类)。中国198。年以来国家地质矿产部和有关工业部门制定的勘探规范中铁矿矿床勘探类型划分为四类。工类,矿体长度达数千米以上,呈层状、似层状,厚度大,形状,产状稳定、矿石品位分布极均匀或很均匀,矿体中夹层少,构造简单;l类,矿体长度千米以上至数千米,矿体形状较规则,常为层状、似层状或大型透镜体状,矿体形状、产状较稳定,矿石品位分布较均匀,但矿体常受成矿后断裂、岩脉切割,并常有夹层;.类,矿体规模中等,长度数百米至千米,矿体形状不规则,常呈似层状、透镜体状,厚度、产状变化大,矿石品位分布不均匀,夹层或包体较多,构造较复杂;W类,矿体规模小,形状复杂,呈中小透镜体状、脉状、囊状、扁豆状或不规则形状,厚度、产状变化大,矿石品位分布很不均匀,工业矿体多不连续.常组成矿体群,构造复杂。
