华北成盐区古近纪盐矿床赋存特征及开发利用现状

Storage Characteristics and Current Status of Development and Utilization of Paleogene Salt Deposit in Chengyan District in Huabei Province

综述了中国东部华北成盐区地下盐矿的赋存特征:鲁西南亚区和苏北亚区矿体大多赋存于2000m以浅,而渤海湾亚区矿体埋深相对较深;矿体厚度整体较大,最厚超过千米;不同成盐区矿物组分存在差异,但矿物成分整体以石盐为主,仅大汶口盆地见钾盐。结合区内盐矿开发利用现状,提出了盐矿床开发利用过程中存在的问题,并对其合理开发利用提出建议。

This paper comprehensively illustrates the storage characteristics of underground salt mine in Chengyan district which is located at Huabei province. The most ore-body of Southwest-Shandong Asia District and North-Jiangsu Asia District exist at underground 2000m or shallower, and the ore-body of Bohai Bay Asia District exist at deeper position. The overall thickness of orebody is big, for example, the most thickness position exceeds one kilometer. The mineral constituents in different Chenguan districts are different. However, the mineral constituents most consist of rock salt, and the sylvite only can be found at the Dawenkou Basin. This paper according to the development and utilization status of salt mine in this district, comes up with the problems during this process and gives some suggestions for the reasonable development and utilization.
