Khvorost V. Explanation of span structures on the mines surface characteristics with account of transition to eased cladding structures

Thesis is devoted to the urgent scientific and technical problem explanation analysis of span structures on the mines surface characteristics with account of transi-tion to eased cladding structures on the basis of dynamic characteristic principles. Computer simulations results by finite elements and theoretical calculation me-thods allowed analyzing the dynamic processes in span structures galleries and estab-lishing principles of its strength defection. Experimentally obtained dynamic processes in span structures are used for strength, resistibility, endurance evaluation of dynamically loaded span structures. Obtained results based on the results of dynamic processes in galleries struc-tures are used for recommendation formulation to determine the resonance zone width and dynamic index value of span structures under conditions of transition to eased cladding structures. Implementation of effective cladding structures of span structures allows re-ducing the cost of span structures reconstruction an average of 10…20 %.
