为了探讨鹤岗兴安矿深部软岩水理特性和塑性变形原因,分别在埋深500和740 m的不同岩性特征处,选取5个试样,采用扫描电镜-X射线能谱仪,对该矿深部软岩矿物成分与微观结构进行实验分析。结果表明：兴安矿深部软岩中主要矿物成分为石英、长石、方解石及黏土矿物,各别试样中含有菱铁矿和金红石。黏土矿物的主要成分为伊/蒙（I/S）混层、伊利石、高岭石、绿泥石等。I/S混层中蒙脱石的类型有钠蒙脱石和钙蒙脱石。碎屑矿物中有石英加大、方解石溶蚀、长石淋滤、菱铁矿解理发育等现象。黏土矿物I/S混层主要呈片架结构、蜂窝结构和絮状结构,高岭石呈书本状结构,伊利石与绿泥石呈片架结构。

Aimed at investigating the hydrological characteristics and the plastic deformation of the deep soft rock for Xing’an mine in Hegang,this paper describes the study of mineral composition and the microstructure,based on five samples selected from the 500 m and the 740 m in buried depth,and using SEM-EDS techniques.The results show that the deep soft rocks occurring in Xing’an mine consist mainly of the Quartz,Feldspar,Calcite and some other clay mineral,except some specimen containing Siderite and Rutile.The primary mineral ingredients of clay mineral are Illite mixed layer（I/S）,Illite,Kaolinite,Chlorite and so on.The Illite mixed layer is composed mainly of sodium-montmorillonite and Ca montmorillonite.Quartz overgrowth,Calcite dissolution,Feldspar leaching,cleavage-growth of Siderite are all found in the test of detrital minerals.Illite mixed layer shows laminated,honeycomb and flocculated structure.Kaolinite shows booked structure.Illite and Chlorite are of laminated structure.
