Study of Methods for Determining the Thickness of Safe Roof in Open Casting Turn to Underground Mining

Abstract:

Aiming at the problem of determining the interlayer thickness from open-casting to underground mining and based on a practical situation of a mining, the safety thickness was determined by using the Thickness and cross-ratio method, Structural mechanics simplified beam method, Protodyakonovs theory and K.B.Lu peiniet theory, According to the least square algorithm and achievement by MATLAB to determine the best weights of safe thickness.
