Abstract

During the construction of inclined shafts mouths in Kuzbass mines cast-in-situ concrete or reinforced concrete support is applied. Due to coal production increase, there is a necessity to build new coal enterprises, and as a consequence, the necessity to construct inclined shafts and mouths of the inclined shafts in coal mines. As the reinforcement of concrete support, metal frames of H-beams [1] or special mining profile are used. Sometimes interlocks do not fully cope with the task. The type ZPKm interlock was tested in JSC KuzNIIshahtstroy, in the result of these tests the dependences of vertical displacement of the interlocks from the vertical load were received. The authors of the article propose the interlock which is patented under number 77906. Also the tests of metal frame supports in tough and flexible conditions were carried out. On the basis of tests, the dependences were constructed, they became the basis for the development of a new reinforced concrete support construction which was patented # 59726.
