江西新余良山铁矿合理勘查工程间距研究
|
摘要
江西新余良山铁矿属典型的"红绸舞"式铁矿,其勘查经历了对构造认识从"单层加断层"观点到多期褶皱叠加并伴随变质作用的过程,勘查类型及勘查工程间距也随着对矿区构造的不断深入研究逐步合理化。勘查中通过对复杂褶皱形态研究,提出了褶皱全息律,处于同一变形体系中的微小褶皱是大褶皱构造的近似缩影。良山铁矿体内微小褶皱、铁矿层变化规律性与矿床地质构造、区域地质背景具自相似性。褶皱构造形态的协调性,其本质在于新余铁矿田构造系统是在同一物质系统(南华纪含铁岩系)、同一成矿作用系统、同一动力作用方式相似变形机制下形成的全息体。经探采对比研究,表明新余良山铁矿确定为第Ⅱ勘查类型(偏复杂)的划分是合理的、适用的。采用200 m×100 m的基本工程间距,同时重视对褶皱端的控制,有效解决了褶皱形态复杂铁矿的勘查难题,成为复杂类矿床勘查的典范,突出了勘查工作对地质规律研究的重要性。
Liangshan iron mine in Xinyu, Jiangxi province is a typical "red silk dancing" type iron ore. Its exploration has gone through the process of understanding the structure from the point of view "single layer plus fault" to the superposition of multistage folds and accompanied by metamorphism,the exploration type and exploration engineering space are rationalized with the deepening study of the mining area structure. Through the study of complex fold morphology, the holographic law of fold is proposed. The small fold in the same deformation system is the approximate miniature of the great fold structure.The regularity of microfolds and changes in Liangshan iron ore deposit is self-similar to its geological structure and regional geological background.The harmony of fold structure morphology,its essence lies in that Xinyu iron ore field tectonic system is a holographic body formed under the same material system(Nanhua iron bearing rock series) under the same metallogenic system and similar deformation mechanism of the same dynamic action.By exploration and mining contrast,Liangshan iron ore as Ⅱ exploration type(partial complex) is reasonable and applicable.The basic engineering spacing of 200 m × 100 m, at the same time pay much attention to fold the control, effectively solved the difficult problem fold form complex ore exploration,which becomes a complex class model of ore deposit exploration.The importance of exploration to the study of geological laws is highlighted.
