中文摘要: 为了解决黄金开采过程中由于数据不足和参数偏差等不确定因素导致的地质特征分析难度大的问题,提出一种基于钻孔土层参数的黄金开采地质特征三维模拟方法,以改进资源储量估算的准确性。采用钻探设备获取钻孔土层信息,并利用距离反比加权差值法优化钻孔土层参数,建立包含地质参数的数据库。基于这些参数,可以使用Surpac软件来构建具有地下空间的三维模型,生成黄金开采区不同地质特征。实验测试结果显示:该钻孔土层参数能够构建较为理想的黄金开采区地下空间三维模型,同时还能模拟出地下空间黄金开采不同深度的地质特征,划分出研究区域的断裂带以及金矿分布、侵入岩位置,准确估算出金矿储量,误差值在2%以内。所提出的基于钻孔土层参数的黄金开采地质特征三维模拟方法具有较高的可行性和准确性。该研究方法的应用可以提高黄金开采区地质特征分析的准确性和可信度,有助于更好地理解研究区域的地质环境,为黄金开采过程中的决策制定提供准确的地质数据支持。
Abstract:In order to solve the problem of difficulty in geological feature analysis caused by uncertain factors such as insufficient data and parameter deviation during gold mining, a three-dimensional simulation method of gold mining geological features based on drilling soil parameters is proposed to improve the accuracy of resource reserve estimation. Drilling equipment is used to obtain information on the drilling soil layer, and the inverse distance weighted difference method is used to optimize the drilling soil layer parameters, establishing a database containing geological parameters. Based on these parameters, Surpac software can be used to construct a three-dimensional model with underground space to generate different geological features of the gold mining area. The experimental test results show that the soil parameters of the borehole can construct a relatively ideal three-dimensional model of the underground space of the gold mining area. At the same time, it can also simulate the geological characteristics of different depths of gold mining in the underground space, divide the fault zones and the distribution of gold deposits and the location of intrusion into the rock in the study area, accurately estimate the gold reserves, with an error value of less than 2%. The proposed 3D simulation method for geological characteristics of gold mining based on drilling soil parameters has high feasibility and accuracy. The application of this research method can improve the accuracy and credibility of geological feature analysis in gold mining areas, help to better understand the geological environment of the study area, and provide accurate geological data support for decision-making in the gold mining process.
