Realizacja upodatnienia zmechanizowanej obudowy ścianowej

W artykule przybliżono problematykę doboru zmechanizowanej obudowy ścianowej do warunków górniczogeologicznych. W oparciu o przegląd literatury zdefiniowano pojęcie upodatnienia i przedstawiono dotychczas stosowaną w tym zakresie metodę. Zaprezentowano wyniki badania, w oparciu o które zaproponowano prowadzenie ocen upodatnienia po zakończonej eksploatacji ściany.

This paper describes the issue of increasing the flexibility of a powered roof support. The authors present an innovative method for optimising flexibility, which was developed by the engineers from the Renovation and Production Facility of Polska Grupa Górnicza S.A. as well as a method used so far, which was developed by the Central Mining Institute in Katowice. The results of the calculation of powered roof support overload as a result of rock mass shocks in a longwall according to declared and projected parameters and the results of a dynamic test of a hydraulic prop were demonstrated. The authors suggested that in order to improve the method for selecting a powered roof support for longwall excavations where there is a risk of rock mass shocks (especially those classified under the 2nd rock burst hazard class), a method for the analysis of powered roof support flexibility after its operation in a longwall is completed (and before its installation in another longwall) should be introduced and combined with station-based tests.
