勘探工程对金矿地层特征分析及探究

Analysis and exploration of geological characteristics of gold deposits in exploration engineering

勘探钻进受地层产状影响,钻孔易出现误差。该矿区钻孔质量要求高,通过钻探、坑探、采样、岩芯化验等对矿区金矿进行全方位的分析及探究,其岩芯指标较为详细。通过五个钻孔钻探任务的实例分析研究,总结出了一系列详细的矿区岩性数据及开采利用分析数据,资源储量,扩大矿区远景,为深部扩界提供地质依据。查明了矿区内地层、构造及岩浆岩特征;通过对矿体进行硐探、钻探工程深部控制,基本查明了矿体的形态、产状、规模及品位变化情况;对矿体的矿物成份、矿石质量、物理性能及矿石加工技术性能有了进一步的了解;估算了该区段的资源储量,对矿床的经济意义也作了评价。

Exploration drilling is susceptible to errors due to the influence of geological formations.The drilling quality requirements in this mining area are high,and comprehensive analysis and exploration of the gold mines in the mining area are carried out through drilling,pit exploration,sampling,core analysis,etc.The core indicators are relatively detailed.Through the analysis and research of five drilling tasks,a series of detailed lithological data and mining utilization analysis data of the mining area have been summarized,including resource reserves,expanding the prospects of the mining area,and providing geological basis for deep boundary expansion.Identified the characteristics of strata,structures,and magmatic rocks within the mining area;By conducting underground exploration and drilling engineering for deep control of the ore body,the morphology,occurrence,scale,and grade changes of the ore body have been basically identified;Further understanding of the mineral composition,ore quality,physical properties,and ore processing technology performance of the ore body;The resource reserves of this section were estimated,and the economic significance of the deposit was also evaluated.
