对三山岛金矿的花岗岩进行不同化学溶液作用下的腐蚀试验,利用三轴测试系统、超声波测试以及离子色谱检测等试验手段,对不同化学溶液侵蚀环境下花岗岩的宏观力学特性及微观物理、化学变化作进一步的探索。试验发现:与自然干燥状态相比,经不同水化学溶液腐蚀后的花岗岩试件出现了相应地软化,水化腐蚀作用通过水中化学成分与岩石活性矿物的反应造成岩石颗粒活化、迁移、溶解并产生裂隙结构,导致岩石的孔隙性与非均质性增大,并使得其物理力学特性变差。
The corrosion tests of granite under Sanyanshijin Gold Mine under different chemical solutions were carried out by using three-axis test system, ultrasonic test and ion chromatography. The macroscopic mechanical properties and microscopic physical and chemical properties of granite under different chemical solution erosion environments were studied. Change for further exploration. It was found that the granite samples that had been corroded by different aqueous chemical solutions appeared to soften accordingly compared with the natural dry state. The hydration corrosion reaction resulted in the activation, migration and dissolution of the rock particles through the reaction between the chemical composition of the water and the rock active minerals Resulting in cracks in the structure, resulting in increased porosity and heterogeneity of the rock and detracting from its physical and mechanical properties.
