【摘要】 随着浅部矿产的日益减少,勘探工作逐渐向矿区深部发展,寻找深部第二成矿空间成为矿山找矿突破的新途径。针对深部隐伏矿定位难题,经多年研究,提出以"定位模型-成矿信息-三维预测"为主线的隐伏矿体三维可视化预测方法。矿体定位概念模型实现成矿规律到矿化分布规律的转换,获得矿体空间定位量化指标;采用形态分析、距离场或缓冲区分析、蚀变场分析等空间分析方法,分析和成矿信息定量指标;采用非线性多元回归、三维模糊证据权等方法,建立矿体三维预测模型,对深部体元的含矿性、品位和金属量进行预测。以安徽铜陵凤凰山铜矿和金川铜镍硫化物矿床为例展开矿区深部三维可视化预测研究,结果显示,该方法能够适用于不同类型矿床的深部找矿工作,对于深部找矿具有重要意义。更多还原

【Abstract】 With the reduction of shallow mining deposits, exploration work gradually turns to the deep mining area. As a result, looking for a second deep metallogenic space is regarded as a new way to make breakthrough in mine prospecting. Based on previous research, this paper proposes a 3D visualization prediction method for concealed ore bodies in the deep mining area. In our method, 3D geological modeling and metallogenic information extraction are applied to traditional metallogenic prognosis. In order to verify the correctness and applicability of the method, we take the copper mine of Fenghuangshan in Tongling, Anhui and Jinchuan Cu-Ni(PGE) sulfide deposit as examples to start our research on 3D visualization prediction in the deep mining area. The outcomes show that the method can be applied to the deep prospecting work of different types of ore deposits and the prediction results are true and reliable and have a great significance for deep ore prospecting.*更多还原
