摘要
针对石材矿勘探和开发中存在的矿体边界确定、石材完整性判别等实际难题,首次将高密度电法技术引入到石材矿探测中,在新疆哈密黄山南黑冰花型石材矿开展了探测研究。通过改造测线布置方法、优选装置,获取了高分辨率的测量数据;进行二维反演和三维电阻率成像反演,实现了三维电阻率数据体在三维可视化环境下的交互式显示和操作;结合地质资料,完成了对石材矿的探测解释及评价。结果表明:高密度电法能清晰地刻画出具有高电阻率特征的石材矿矿体三维空间形态,对影响石材矿质量的风化层、裂隙构造等不利因素有较强的识别能力。
Electrical resistivity imaging（ERI） was introduced to stone mineral exploration in order to resolve some actual problems such as ore body boundary determination and integrality distinguish.The ERI was used in a Heibinghua stone deposit exploration in Xinjiang.High resolution survey data was acquired by change survey line dispose and select appropriate equipment and then both 2D inversion and 3D tomography was done based on these dataset.The inversion results can be display,operate interactively realized by 3D visualize technology and then accomplish both interpret and evaluation for stone mineral.The result of ERI exploration indicate that this method can depict 3D shape of stone ore which have high resistivity,and it also indicate that ERI have stronger recognition capability for disadvantage factor such as mantle rock and cranny.
