The West Two Of MengDong Opencast Stability Of South Dump

Slope stability is an important part of opencast mining, but also th e hot topic of mining engineering studies. Opencast Coal Mine is seco nd only to the huge mining field structures, it accepts asylum geotechn ical open pit waste stripping. Therefore, for opencast coal mine, waste rock dump and calculate emissions requirements is very high, especially the stability design. With large-scale mining of Mengdongxier surface coal mine, the slope stability will affect the mining production and aff ect the progress of mining. And it will also bring great security risk f or waste dump base equipment and personnel security. Aiming at the s ituation and geological conditions of Mengdongxier Second Opencast en gineering, the stability of the dump is analyzed.Combining with the outcast mechanics index and landslide model, we use the stability coefficient of the selected profile by the limit equi librium calculate. And then, using ANSYS, FLAC3D to simulate the 2D status chart, stability study provides a scientific basis for Mengdongxi er surface coal mine, but also provides a reliable reference basis for ot her dumping stability analysis.
