Migration and Stress Distribution of Working Face with Vertical Overbite Main Roof
-
Abstract
According to occurrence of 1602(3) working face, we analyze advance abutment pressure distribution and its peak and effect range through numerical simulation and filed measurement. We also analyze roof's vertical stress distribution, and judge range of strata fracture, abscission horizon and key stratum. Through filed measurement, we got periodic weighting length, and affected areas by mining.
