Abstract. The mining of large underground potash deposits presents an unusual challenge because the quantity of ore to be mined is very large, the value of the ore is relatively low, there is extreme competition, and most dominately, at the depth of many potash mines there are severe stress and creep (plastic flow) problems.Web
