abandoned surface mine excavations can be a major environmental, social and/or human healthproblem for the mining industry as well as for the community living nearby. this problem is exacerbated by therapidly growing population encroaching on areas of historic mined lands. the aim of this studywas to assess thesafety status of the historic nyala mine excavation with the purpose of coming up wit...

Disposal of greywater is a neglected challenge facing rapidly growing human populations. Here, we define greywater as wastewater that originates from household activities (e.g., washing dishes, bathing, and laundry) but excludes inputs from the toilet. Pollutants in greywater can include both chemical and biological contaminates that can significantly impact human, animal, and environmental hea...

In-pit crushing and conveying (IPCC) systems have drawn attention to the modern mining industry due numerous benefits than conventional truck-and-shovel systems. However, implementation of IPCC system can reduce flexibility introduce additional sequence requirements. This paper investigates long-term production scheduling crusher relocation plan open-pit mines using a semi-mobile high-angle con...

Abstract Since the safety and stability of original tunnel structure are easily affected by adjacent foundation pit excavation, it is strongly necessary to study deformation evolution tunnels during excavation. With regard two cases that adjacently located at right bottom pit, influence different supporting methods, including pile support, bolt pile-bolt shotcrete-bolt on was investigated basis...
