大安纳多利斯克耐火材料联合企业露天矿开采弗拉基米尔斯克矿床的次生高岭土,是一种有价值的高铝粘土原料。该高岭土矿主要含有2～3个品级层,并以其高砂性(细散状均布砂粒达20%)、低可塑性和粘性、高研磨性而区别于其它耐火粘土和高岭土矿床。该矿床水文地质条件复杂、含水性高,由此降低了采场底板的承载能力,增大了高岭土在工作机构和采掘设备转载装置部件上的粘结和冰冻作用。该联合企业最初在其下属部门的开采工
The secondary Kaolin clay found in the Vladimirsk deposit by the Grand Unionat Refractories Joint Venture is a valuable source of high-alumina clay. The kaolin mine mainly contains 2 to 3 grade layers and is distinguished from other refractory clays and kaolin deposits by its high sand content (up to 20% finely distributed sand), low plasticity and viscosity, and high abrasiveness. The deposit is characterized by complex hydrogeological conditions and high water content, thereby reducing the bearing capacity of the stope floor and increasing the bonding and freezing of kaolin on the components of the working mechanism and the mining equipment transfer device. The conglomerate initially hired workers in its subordinate departments
