| الوصف: | The article discusses feasibility of secondary mining of natural–manmade sylvinite seam KrII* in the Upper Kama Potassium Salt Field. The full scale tests of large samples were carried out to determine mechanical properties of seam KrII*. Mathematical modeling provides estimates of load exerted on nonuniform safety pillars after secondary mining. The authors propose alternative flow charts for the secondary mining of natural–manmade seam KrII* to ensure safety and reasonable efficiency of production. |
