阿拉伯谷地的冶金考古--"所罗门铜矿"之争

由奔诺·罗森伯格领导的对“阿拉伯谷地”古铜矿冶遗址持续几十年的发掘和研究 ,在冶金考古方面取得了巨大的成就。古埃及哈托尔矿业神庙的发现证明所谓的所罗门的铜矿实际上属于古埃及。具重要意义的是在提姆纳第 3 9号遗址发现了迄今为止考古学家所找到的年代最古老的炼铜炉。遗址的采矿和冶炼技术反映出了早期矿冶状况和冶金技术对人类文明的推动作用。“阿拉伯谷地”古铜矿冶遗址考古的出色工作成为全世界相关学者的典范     

矿山关闭及其生态环境恢复分析

矿山关闭及其生态环境恢复已成为我国的研究重点和难点，但其关闭的科学程序与相应措施还未得到深入研究。本文从矿山可持续发展角度，针对矿山关闭中存在的问题，本文根据国内外相关文献和我国矿山关闭现状情况．阐明矿山关闭及其生态环境恢复中存在矿企外部成本转嫁、产权配置效率低、缺少闭矿规划和忽视生态安全等的问题．在闭矿后合理发展生态农业是缓解经济衰竭的重要措施．并提出编制闭矿规划、调整产权关系、生态环境乡土化、加强矿区地质环境与生态环境的监测、发展特色旅游事业等相应建议。

Low-temperature geothermal potential of the flooded Gaspé Mines, Québec, Canada

The low-temperature geothermal potential of the flooded Gaspé Mines, near Murdochville, Québec, Canada, has been estimated from a long-term pumping test and numerical groundwater flow modelling. A former mining shaft was used to pump water for 3 weeks at a rate averaging 0.062 m³/s (3720 L/min). A mean recovery temperature equal to 6.7 °C and a maximum drawdown of 3.63 m were observed during this test. The observed drawdown was reproduced with a three-dimensional finite element model that simulates groundwater flow through the mine workings and surrounding rock mass. The model was then used to simulate longer-term pumping performed for heat recovery. Modelling results combined with a simplified energy balance calculation suggest that a sustainable energy extraction rate is attained at a pumping rate of 0.049 m³/s (2940 L/min), with a corresponding geothermal energy production potential of 765 kW, assuming a return water temperature of 3 °C. This energy could be extracted with heat pumps and used for space heating at the town's industrial park.     

Materials selection to excavator teeth in mining industry

Hard alloys are normally used as materials for excavators teeth in mining industry. In most cases these alloys do not have enough anti-wear properties and coatings are employed as a good alternative. The objective of this work is to test the abrasive wear resistance of several cast irons alloyed with different elements. Laboratory tests based on the ASTM G105-89 standard were compared to tests carried out under real working conditions of excavator teeth in mines.

The experimental results show an acceptable correspondence between laboratory and field tests. To complete the laboratory research, hardness and microhardness measurements and optical micrographs were performed to identify the mechanism of wear. As a result of the experimental work, an economic evaluation of materials was also performed.
