摘要
刚果(布)钾盐矿为固体矿床,采用房柱式开采方法,晶间卤水通常赋存于石盐晶间孔隙中,对旱采钾盐固体矿井形成水害威胁,影响开采正常进行.通过分析刚果(布)钾盐矿床晶间卤水具有沉积物以同生沉积为主的形成条件,分布特征受古地理、 构造影响,按照晶间卤水赋存成因划分,可分为岩性组合、 断层型、 凹陷型、 断层凹陷复合型三大类,为钾盐矿井防治水工作提供地质及水文地质依据,对矿井安全生产具有重要的意义.
The sylvitedeposit in the Republic of Congo is a solid deposit,which adopts the room-pillar mining method.The intercrystalline brine usually occurs in the intercrystalline pores of the rock salt,which poses a water hazard to the dry mining of sylvite solid mine and affects the normal mining.By analyzing the intergranular brine of sylvitedeposit in the Republic of Congo,the formation conditions of sediments are mainly sedimentary.The distribution characteristics are affected by paleogeography and structure.According to the intergranular brineoccurrence genesis classification,it can be divided into lithology combination,fault type,depression type and fault depression type,which provides geological and hydrogeological basis for the water prevention and control of sylvite mine,and has important significance for mine safety production.
