摘　　要：分析了我国复杂难采矿床包括“三下”矿体(特别是厚大第四系岩层、流沙含水层和大水矿床等)、矿岩松软破碎及其它工程地质环境复杂矿体、空间形态复杂多变难采矿体、残留矿体(民采残留和境界外矿体等)、露天矿山深部矿体等主要类型和这些复杂难采矿床在开采中存在的主要问题,最后提出了解决这些问题的对策措施。The main types of China＇s complicated hard-to-mine deposits and the main problems in their exploitation are analyzed, which include “three unders” deposits （especially thick tertiary system rock stratum, flowing sand water-containing stratum and heavy water deposits）, soft and fractured or other engineering geological environment -complicated deposits, spatial shape -complicated and variable deposits, residual deposits （left by civil mining or outside boundary ）and deep deposits in open-plt mines. Finally, the countermeasures for solving these problems are proposed.
