Abstract:Shrinkage stopping is suitable for the mining of steeply-inclined thin to medium-thick orebody. It has the characteristics of low mining cost and simple technology, but it also has some problems, such as high safety risk, and personnel working under exposed roofs for a long time. SHAN Hu ore is a typical steep thin ore body. In the process of shallow hole extraction, there are some problems, such as large blasting blocks, unreasonable stope structural parameters, and poor roof stability. Through theoretical analysis, engineering analogy, and other methods and means, the stope structural parameters, drilling and blasting technology, support technology, and mining equipment are optimized. Various technical and economic indicators have been greatly improved. It provides good engineering practice and a theoretical basis for similar mines.
