摘要
江苏省东海县双湖矿区建筑用片麻岩为宋山二长片麻岩的一部分,矿区范围即矿体范围.矿石自然类型为二长片麻岩,水饱和抗压强度为70.0～165.5MPa;组合分析测试结果显示优于建筑用石料I类要求,矿石的吸水率满足建筑用石料要求,矿石化学成分中有害物质含量符合建筑用石料Ⅱ类指标要求.矿石加工技术性能结果显示,建筑用片麻岩矿经加工后的产品均可满足相应的利用要求.
Abstract
The construction gneiss used in Shuanghu mining area,Donghai county,Jiangsu province is a part of Songzhuang Erchang gneiss.The mining area refers to the range of the ore body.The natural type of ore is diorite gneiss,with a water saturated compressive strength of 70.0～165.5MPa;The combination analysis test results show that it is superior to the Class Ⅰ requirements for building stone materials.The water absorption rate of the ore meets the requirements for building stone materials,and the content of harmful substances in the chemical composition of the ore meets the Class Ⅱ index requirements for building stone materials.The performance results of ore processing technology show that the processed products of building gneiss ore can meet the corresponding utilization requirements.
