摘要
眉山市芒硝矿以含钙量高、矿物晶体较大、埋藏浅、规模大为特点,目前采用洞室水溶法开采。钙芒硝生产过程中主要环境地质问题是地下水疏干。这给矿山及附近居民的生产、生活带来较大的影响。通过对其形成机制的分析,可采取工程措施进行治理。
The Meishan mirabilite ores are characterized by high Ca content, large mirabilite crystalline, shallow occurrence depth and giant reserves. The ores are mined by chamber solvent extraction. The mine water drainage has serious influence on the environment. It is necessary to control measure based on the genetic mechanism.
