摘要
威西矿床地质勘探井,大部分施工于60年代末70年代初,至今已有40年左右,在自贡辖区内分布有9眼地探井。地探井属无主矿井,自1987年以来,一些探井相继发生井眼及周边岩层裂隙泄漏卤水,造成农田、井泉污染、坡坎垮塌等灾害,给附近的村民带来了一定的损害。本文分析了威西岩盐矿床的地质特点、地探井污染的预防与治理的技术难点与治理方法。
Most of the geological exploratory wells in Weixi rock salt mine were constructed in late 1960s or early 1970s.About 40 years have passed.There are 9 wells in Zigong area.They are dereliction wells.Since 1987,brine spllage from or around some of the wells have resulted in the pollution of farmland and well spring and collape of slopes and ridges,bringing certain damages to the farmers nearby.This paper analyzes the geological characteristics of Weixi rock salt deposit,the technical difficulties of the pollution prevention and treatment and measures to be taken.
