21世纪矿业应向后工业发展势态倾斜--适者生存和可持续发展 总被引:5,自引:0,他引:5
“后工业”(post-industry)是知识经济或曰“新经济”的发展时代。这个时代的自然资源和一般劳动力资源,包括矿产资源在国民经济和社会发展中的基础地位逐渐为知识产权、市场网络、信息、创新环境等后天获得性资源,以及为创新人才的新“认知”(recognized intellect,RI)所代替。然而,据矿产资源分布及其成矿既具有一定的全球统一性又有区域的特殊性,以及不同国家(地区)对矿产资源勘查程度的不均衡性,特别是矿业活动与其他产业性质的不同,如何能按不同国家(地区)的具体发展状况,做好21世纪矿业向“后工业”发展势态的倾斜,达到适者生存和矿业可持续发展的目标是当代探讨的重大问题。在概括阐述了21世纪矿业发展势态、矿业活动特点及其自然属性的基础上,提出了矿业可持续发展的地质勘查和矿业活动决策支持系统的模拟,以及对当前紧缺铜矿资源可持续发展的新“认知”。 相似文献

The newly independent country of Timor Leste is located in the eastern half of Timor Island (Indonesian archipelago). Geological studies of the country’s mineral resources and extractive activities are practically non-existent. There is evidence of the exploitation of ceramic raw materials at outcrop level and two small brick kilns, nowadays inactive, in the Dili and Aileu areas. Near Aileu, there are light-coloured silt-rich deposits, interpreted as overbank deposits, interbedded with ancient river terraces (post-Pliocene) overlying metamorphic bedrock. These sediments are the subject of this study, which encompassed geological mapping and preliminary characterisation. Tectonically, the area is a graben, preserving alluvium and colluvium deposits. Five channel samples representative of the silt-rich deposits were collected. Semi-quantitative mineralogical analysis shows that the samples are made of illite, quartz and kaolinite clays, with accessory illite/vermiculite interstratified minerals and K-feldspar. The chemical data show agreement with the estimated mineralogical composition. The grain size distribution points to a silt-dominated assemblage. Most samples have a satisfactory extrudability but deficient moulding properties. After firing, the sampled raw materials form a final product with possible ceramic capability for whiteware production. 相似文献

Trends in location, labor force, and procurement practices in maquiladoras are examined using recent data sources. A growing proportion of maquiladoras are selecting interior locations, south of the borderlands. Once dominated by young women, the labor force is rapidly approaching gender parity. While far below prevailing rates in the United States, maquiladora wages are comparable with equivalent manufacturing sectors in Mexico. Majority ownership of maquiladoras is split almost evenly between Mexico and the U.S., however, maquiladoras have failed to develop domestic sources of materials and parts and remain dependent on imported material inputs. As the North American Free Trade Agreement is phased in, the regulatory environment of maquiladoras will change but their role as low cost assembly specialists will persist. 相似文献

This paper presents a methodology used to combine energy and mineral market variables between Less Developed Countries (LDCs)
and Developed Countries (OECD) over the past 24 years (1966–1990). LDCs include all countries, except OECD and central planned
economies (CIS) and other countries in Eastern Europe. This period permits a comprehensive view of the impact of the energy
crisis and the changes in economic growth patterns, correlated with changes in trends of production and consumption of energy
and metals in both country blocs. This complex relationship was evaluated by a factor model of consumption and production
variables using the aluminum, copper, lead, and zinc industries. The following variables are used in the factor model: export
dependence, geographic concentration of mining production, geographic concentration of refined demand, geographic concentration
of refined production, import dependence, refined demand growth, stability of demand, income elasticity of refined demand,
price stability, intensity of use, and intensity of energy. The model for all commodities shows that the factor scores projections
for LDCs and OECD blocs depicted a clearly divergent trend after the two oil shocks (1973–1979), when the intensity of energy
variable presents high loading in the factor. The results are in substantial agreement with findings that the demand for energy,
as well as for metals, is growing more rapidly in LDCs than OECD. 相似文献
