地球物理测井在吉林省磐石市马鞍山石墨矿勘查中的应用

Application of geophysical prospecting geological exploration of Ma’anshan graphite mine in Panshi City,Jilin Province

针对石墨矿体的物理性质,选择合理有效适合的地球物理测井方法,通过地面物探如自然电场法、激发极化法在石墨矿区寻找靶区、找出有进一步工作价值的区域,再利用钻探和测井方法确定矿体的地下空间位置及矿石的固定碳含量等各项指标,认识矿体赋存规律。

According to the physical properties of the graphite ore body,a reasonable and effective geophysical exploration method is selected. In the past,ground geophysical exploration,such as natural electric field method and induced polarization method have been used to find target areas and identify areas of value for further work in graphite mining area. Then,drilling and logging methods are used to determine the underground space position of the ore body and the fixed carbon content of the ore,so as to understand the occurrence law of the ore body.
