摘　　要：给出了孔道结构的定义。重点介绍了包括钠沸石、浊沸石、钙十字沸石、菱沸石、丝光沸石、坡缕石、海泡石、绿柱石、异极矿、软锰矿、拉锰矿、锰钾矿、硬锰矿、钙锰矿、水锰矿、黄磷铁矿、磷钠铍石和磷灰石等在内的硅酸盐类、锰的氧化物和氢氧化物类 ,以及磷酸盐类等具有孔道结构的天然矿物和它们的结构特征。简要论述了具有孔道结构的矿物在环境修复和治理中有广泛应用的吸附效应、孔道效应和催化效应 ,认为具有孔道结构的矿物在未来的环境属性开发、化学和生物改性以及合成孔道矿物方面会有很好的应用前景。The definition and classification of tunnel structure minerals are proposed. The framework characteristics for typical tunnel structure minerals are described in detail,such as natrolite, laumontite, phillipsite, chabazite, mordenite, palygorskite, sepiolite, beryl, hemimorphite, pyrolusite, ramsdellite, cryptomelane, psilomelane, todorokite, manganite, cacoxenite,beryllonite and apatite,which belong to silicate, manganese oxide and hydroxide minerals and phosphate respectively. The effects of surface absorption, tunnel structure and catalytic reaction, which were applied in the field of harnessing contamination and remedying environment, are also discussed. The tunnel minerals will play important roles in the future development of the exploitation of environmental properties, chemical and microbial modifications as well as synthetic tunnel structure minerals. =
