运城盐湖的开采,据载已有两千五百多年的历史。解放以后,盐湖转以开采芒硝为主,石盐生产退居次要地位。据运城盐化局统计,自1950～1969年共产芒硝730.42万吨,石盐99.91万吨。该地区尚有解州化工厂,成立于1958年,20年共产硝100万吨。 然而,近些年来,由于地下水位普遍下降、地表水源渐绝,严重威胁盐湖的生存。盐湖的蕴藏量究竟还有多少?还能开采多少年?这成了人们极为关心的问题,也涉及到它的建设规模与长远规划。笔者近年在这些方面做了一些探索,撰写成文,敬请读者指教。
The mining of the Salt Lake in Yuncheng has been recorded for more than two and a half centuries. After the liberation, Salt Lake turned to the exploitation of thenardite-based, stone salt production relegated to a secondary position. According to the statistics of Yuncheng Bureau of Salinization, there were 730.42 million tons of Glauber salt and 999,100 tons of salt stone from 1950 to 1969. There are still chemical factories in the region, was established in 1958, 20 years a total of 100 million tons of nitrate. However, in recent years, due to the general decline of groundwater table, the surface water source gradually declined, which seriously threatened the survival of the salt lake. What is the reserves of salt lake? How many years can we still mine? This has become a matter of great concern to people, as well as its construction scale and long-term planning. In recent years, I made some explorations in these areas, writing written, please readers advice.
