theoretical review of ‘mining pit lakes’ indicates that like natural lakes such lakes display a huge diversity. they are typically in a non-equilibrium state with respect to their surroundings. hence, at the decommissioning phase of mining operation a detailed technical study are required on different aspects of such created water bodies considering its morphometry, geology, hydrology, water qu...

Hillslope processes and mass movement are key issues in the analysis evaluation of geological disasters mountainous regions. A rockfall-dominated talus slope exhibits a typical outcrop–talus system as product detached boulders rock fragments. The Zongling rockfall zone is one most active systems southwest China, it provides representative case study on assessment hazards at base slopes. In this...

PT. Bukit Asam Tbk is an open-pit coal mining company in Muara Enim, Soutgh Sumatra. In activities, slope stability analysis carried out to evaluate the mine order create a safe process. Several types of failure are associated with geological structures. This research was conducted identify type landslides low wall area Pit X and determine factor based on discontinuity data using scanline metho...

Coal gangue is a byproduct of coal mining, and has been piled up for years in China, forming thousands hills, which have become an important part abandoned mining areas. In recent years, the government issued various policies on ecological restoration hills provided economic support. However, relying solely support not long-term solution. The key to improve production efficiency promote their s...

Abstract Mining activities that involve constructing slopes will increase the potential for slope problems, especially those related to increased rock failure. Therefore, an in-depth study of stability is required determine ability stay stable without reinforcement or choose type best fit a if it has significant landslides. This research aims obtain safety factor value sandstone mine in Sedau V...

The electrical resistivity tomography technique is a geophysical inspection method widely used for several investigations, such as mining exploration, fault localization, groundwater flow, geological and pollution zones. Infusing brine into substructure can increase conductivity becomes useful medium to trace the path of seepage flowing in rockfill dams. In this article, an elapsed-time was dev...

block-flexure is the most common mode of toppling failure in natural and excavated rock slopes. in such failure, some rock blocks break due to tensile stresses and some overturn under their own weights and then all of them topple together. in this paper, first, a brief review of previous studies on toppling failures is presented. then, the physical and mechanical properties of experimental mode...
