Support Optimization of 14-1103 Working Face in Zhengli Mine Based on Numerical Simulation

Article Preview

Abstract:

In the process of production of Zhengli mine 14-1103 working face, found that though the existing supporting system can satisfy the requirement of support, there will be a bulge in a few places, anchor invalidation etc. In order to guarantee safe production and high efficiency production requirements, it is necessary to optimize the working face support. In this paper, by the method of numerical simulation, compared the original support and optimized system, test the optimized supporting effect. It’s proved that lengthen the top bolt is an important measure for optimizing the support system.
