CONSTRUCTION DEVELOPMENT HEAD UNIT WHEN MINING WEAKLY STABLE ORE BODIES AT GREAT DEPTHS

The design of artificial bottom block of reinforced concrete using a quick-yielding metal support SVP-22, SVP-27 is recommended for use in the design, located in an array of charged under the zone collapses, ensuring their stability, reliability, durability, clean-up rhythm. Specific reactivity of metallic yielding lining SP-28 when it is installed at 0.5 m is 37-42 t/m(2), representing only 7.5% of the pressure at the bottom caving. The use of artificial-governmental structures, at the very beginning of the preparation of the bottom works as a construction of the bottom-lining. The greatest resistance workings bottom provides a monolithic lining of the early strength concrete.
