| 本研究通过对天全县复兴村玄武岩进行系统化学分析及物理力学性能测试，结合水文地质与工程地质条件，对其在纤维制造和建筑材料领域的适用性进行深入探讨。结果表明，该区玄武岩普遍具有较高的 SiO.含量、适宜的酸度和黏度系数，化学组分介于碱性与亚碱性之间，利于在高温拉丝过程中实现稳定成纤。高强度、低吸水率以及低碱活性等特征则使其在混凝土和高等级建筑结构中表现出优异的耐久性和力学性能。研究区矿山的水文地质与工程地质条件适中，边坡稳定性较高，资源开采具有较好的可行性和安全性。基于上述分析，复兴村玄武岩不仅适合作为高性能玄武岩纤维的原料，而且在建筑骨料等领域亦有广阔的应用前景；若能结合环保理念，科学开发，将有助于推动当地资源优势转化为经济优势，并为新材料产业与区域经济的可持续发展奠定坚实基础。 |
| 英文摘要: |
| This study systematically evaluated the applicability of basalt from Fuxing Village，Tianquan County，in the fields of fiber manufacturing and construction materials through chemical analysis and physical-mechanical property testing，combined with hydrogeological and engineering geological conditions. The results indicate that the basalt in this area generally exhibits high SiO. content，suitable acidity and viscosity coefficients， with chemical compositions ranging between alkaline and sub-alkaline. These characteristics facilitate stable fiber formation. Its high compressive strength，low water absorption，and weak alkali activity make it highly durable and mechanically suitable for concrete and high-grade building structures. The region′s hydrogeological and engineer. ing geological conditions are moderate，with high slope stability，suggesting favorable feasibility and safety for resource extraction. Based on these analyses，basalt from Fuxing Village is not only an excellent raw material for high-performance basalt fiber but also shows promising potential in construction aggregates and other applications.Integrating environmental considerations with scientific development will further enhance the transformation of localresource advantages into economic benefits，providing a solid foundation for the sustainable development of the new materials industry and regional economy. |
