摘要
铝土矿是山西省的优势矿种之一,保有资源储量居全国之首。然而浅部的铝土矿勘查殆尽,后备可开采资源不足,需要加大对中深部隐伏铝土矿的勘查。本次工作在山西省霍西云义地区,利用可控源音频大地电磁测深法(CSAMT法)以及高精度重力测量法,结合钻孔数据,基本查明了研究区的构造断裂情况,初步绘制了奥陶系灰岩侵蚀面并推测出了铝土矿含矿段的赋存范围。这表明本次工作对古喀斯特地貌发育地区减少无效工程的数量和控制边界颇有成效,对今后山西省中深部的煤下铝土矿勘查工作有启示意义。
Bauxite is one of the dominant mineral resources in Shanxi Province, ranking first in the our country. With the growth of alumina production project, the bauxite resources of Shanxi province have been in short supply, but the shallow exploration of bauxite mining resources can be exhausted.With the lack of resources, we need to increase the exploration of deep concealed bauxite. This research used Controlled Source Audio- Frequency Magnetotelluric method（CSMAT method） and high precision gravity measurement method.Combined with drilling data, we ascertain the fault situation of the study area ,draw preliminaryly the Ordovician limestone erosion surface and infer the occurrence position of iron-bauxite rock group. This work provides a theoretical basis for the engineering design and layout for drilling bauxite the next exploration in areas of Shanxi province in the future, at same time the deep coal bauxite exploration plays an important role for the work.
