  • S-160 D Mine Shaft Radio Communication System

    The mine shaft radio communication system is desgned for wireless transfer of verbal information between a hoisting machine operator or a cager working at the edge of the shaft and an operator of the mine-cage on any level within the shaft. Moreover, the system enables communication between the operators of the mine-cage and the shaft bottom.Онлайн-запрос

  • Shaft Mining, Mining Techniques, Underground Mining

    Shaft Mining. Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world.Онлайн-запрос

  • Shaft Sinking Methods: Caisson Method and Cementation

    The drilling of mine shafts by suitable machines is the most progressive method of shaft sinking adopted in Russia and other advanced countries of the west. The process is completely mechanised and all the sinking work can be carried out by sequence controlled automatic machines so that there is no need to keep any men at the shaft bottom.Онлайн-запрос
