UDEC Numerical Simulation Research of Mining Overlying Strata Movement Regulation

Abstract:

The process of fractures developing of coal and rock and overlying strata movement is a temporal dynamic evolution process. In this paper, based on the research object a working face of a mine, using the UDEC numerical simulation software to research the movement of the working face upper strata in mining process, the results showed that the overlying strata forms "vertical three zones" in the vertical direction from bottom to top. Overlying strata above the goaf displays a fracture table with a trapezoid shape entirely; the cut side of the fracture angle is slightly larger than the working face side of the fracture angle. Numerical simulation calculation of the height of two zones will get a close consistent result to empirical formula. The conclusions have important guiding significance for reasonable arrangement of the gas exploitation.
