为了进一步对杂怀沟硬质粘土矿石质量有一个比较合理的评价,下面将杂怀沟矿石质量,特别是特级品矿石质量与国内外同类品种进行一些比较,同时对内蒙古自治区硬质粘土资源情况作了一些分析,以供参考。一、杂怀沟硬质粘土矿床地质概况该矿床产于石炭二叠纪煤系地层中,为层状沉积矿床。勘探区矿体东西长700余米,南北宽平均60米,由两层矿组成,上部为硬质粘土夹煤层,出露厚度一般为30～39米,最厚53米,最薄22米,平均35米;下部为优质硬质粘土层,出露厚度一般为15～20米,平均18米,此层为矿山主要开采对象,其特级品矿石多赋存在本层的中下部,又多富集于西部地段,有
In order to further have a reasonable evaluation on the quality of the hard clay ore in Zouhuagou, the following will make some comparisons of the quality of the ore in Qianghuagou, especially the quality of the special grade ore, with the similar varieties both at home and abroad. Meanwhile, the hard clay resources in Inner Mongolia Autonomous Region Made some analysis for reference. First, the heterozygous ditch hard clay mineralization Geological Survey This deposit is produced in the Carboniferous Permian coal strata, stratiform sedimentary deposits. The ore body in the exploration area has a length of 700 meters between east and west and an average width of 60 meters in the north and south. It consists of two layers of mines. The upper part is composed of hard clay intercalated layers. The exposed thickness is generally 30-39 m, the thickest is 53 m and the thinnest is 22 m. An average of 35 meters; the lower part of the high-quality hard clay layer, the exposed thickness is generally 15 to 20 meters, an average of 18 meters, this layer is the main mining targets of the mine, Set in the western lot, there
