Taking a super large deep foundation pit project as an example, the horizontal displacement of crown beam and driveway, surface settlement, axial force anchor cable, underground water level in construction process are dynamically monitored analyzed. The excavation deformation rule influence on surrounding buildings results show that, with pit, driveway incline towards direction eventually tend ...

This paper raises important questions about the way we approach numerical analysis in rock engineering design. The application of advanced models is essential to adequately analyze and design different geotechnical aspects pit-to-cave transitions. We present a critical review methods centered around hypothesis that model not, cannot be, perfect imitation reality; therefore, modelling large-scal...

Sustainable development is about creating a balance between and environment, it consists of three essential principles: society, economy. Today, one the most important challenges in deep open pit mines transition from to underground, which has positive negative impacts on sustainable indexes. In order reduce these adverse impacts, impact various parts operation indexes should be evaluated corre...

one of the main concerns of the mining industry is to determine ultimate pit limits. final pit is a collection of blocks, which can be removed with maximum profit while following restrictions on the slope of the mine’s walls. the size, location and final shape of an open-pit are very important in designing the location of waste dumps, stockpiles, processing plants, access roads and other surfac...
