beneficial in a number of ways. Thanks to the small dimensions of the drill rigs, only small quick-to-produce excavation pits are required which cause only a minimum of excavation. This allows the machines to be used in restricted spaces and densely populated areas, especially since a truck-mounted crane or mini-excavator is sufficient for ...

In soft soil foundations, the utilization of box-type retaining walls as a support method represents a novel approach. This study focuses on investigating the key factors influencing lateral wall deflection and ground settlement behind the wall in deep excavation projects supported by box-type retaining walls. Based on a practical engineering case in …

Open-pit mining is a process of extracting mineral deposits from the earth's crust. An open-pit mine site may consist of several pits, each of which is excavated in a series of phases, benches or so-called "pushbacks" (Wetherelt and Van der Wielen 2011). To design a pit at the strategic level, the whole orebody is divided into block

Hi, I am trying to get an idea of the equipment needed and timeline to excavate a 20x80 by 60 feet deep pit. I am assuming that 2 or 3 excavators will be used on benches to haul the soil out of the pit, about 30,000 CY. How many excavators should be used and how many yards of dirt can each excavator move in a day? Thanks

For light-duty applications, a small dozer may be fine. For large operations, however, there's nothing like the brute strength and sheer pushing power a huge machine can deliver. Besides the blade size, the other main consideration in picking a dozer as construction equipment is its physical size or footprint. Larger machines take larger space.
