马海钾矿床北部矿段资源概略评价及开采

Outline Evaluation and Exploitation of Resources in Northern Segment of Mahai Potassium Deposit

马海钾矿区是一个固、液并存的钾矿床,其工业开发的钾盐主要分布于58—79勘探线12号孔以北,故称北部矿段,分布于地表浅部的固体钾矿和潜卤层中液体矿相伴而生。按照综合利用的原则,固、液矿不仅要同时开发,而且应该依据固、液矿之间相互转换的关系统筹开发。

Mahai potassium deposit is one in which solid and liquid co-exist with each other. Potassium salt for commercial exploiting is distributed mainly in north of the 58-79 survey line and 12# hole called the northern segment. The solid potassium ore in the shallow earth surface is associated with the liquid ore in the latent halogen layer. For the sake of comprehensive utilization, ores of solid state and liquid state should be exploited in a unified way with consideration of transformation between them.
