This paper research on the failure mode of a coal mine dump slope in Inner Mongolia. Firstly, there are some brief introductions of the surface mine dump slope failure mode and the basic principles of Lagrangian; Secondly, the collected geological data is shown. We established the dump slope model by FLAC3D program and than draw conclusions. This method can provide an useful safety information for the opencast coal mine.

South Slope

This paper is aimed at analysing the slope failure model for an open pit slope. Firstly, The method of engineering geological survey is carried out for the open pit south slope. Then, the appropriate geological model is established. And the slope model of the open pits was established and solved by finite elemen program. The analysis reveals the internal sliding of the open-cut and the failure modes of bottom sliding along the base weak level. It will be an important guiding significance for the safe production of open pit coal mine.

Abstract The characterization of failure modes of DRAM is often straight forward if array related hard failures with specific addresses for localization are concerned. The paper presents a case study of a bitline oriented failure mode connected to a redundancy evaluation in the DRAM periphery. The failure mode analysis and fault modeling focus both on the root-cause and on the test aspects of the problem.
