ABSTRACT: In the article the analysis of real exploitation conditions of the systems «vessel ― reinforcement» in vertical shafts is executed, recommendations providing the necessary increase of operating strength security of hoisting plants for the shafts with the broken geometry are represented. The researches are done on the base of application of modern hardware and software measuring complexes, calculation of the correcting impacts localized to address and controlling parameters. These measures are applied to prevent the emergency situations and provide transition of shaft equipment in the state of the equal spreading of set level safety indicator on the depth of shaft, at influence of external factors of difficult technical and mountaingeological conditions with minimum technological economical expenses.
1 INTRODUCTION In the operative mine shafts in the area of mountain breeds movement guides’ deviation from vertical line are the main source of excitation of strikecyclic interaction. Mine shafts are the continuously changing systems, in a different period of time found in different types of the technical state - from normal to emergency dangerous. With the increase of exploitation term speed of possible transition from one state to another increases because of the contemporary accumulation of the concomitant degradation occurrences in the all elements of shafts’ equipment. It is the main source of failures in mine shafts with the heavy material consequences and threat for the people life. The mine winding plant (MWP) is an extensive, multiple-link, multi-oscillatory system with multiple degrees of freedom where links consist of a combination of assumed hard limits of operating parameters and stochastic variables with high variability. During their operation exists strong correlations between mutual influenced dynamic processes where non-localized heterogeneous links influence each other. The operational state of each link is sufficiently characterized by a set of diagnostic parameters with normative values that are both deterministic and stochastic in nature. The functioning deterministic state of the MWP links must work in the projects dynamic operation dampening the presence of the
undue fluctuations influencing the dynamics of other system links. 2 DYNAMIC APPARATUS STATE OF SYSTEM REINFORCEMENT”
