Application of micro-piles to stabilize unstable slopes has been widely considered in recent years. A micro-pile is a small-diameter (typically less than 300 mm), drilled, and grouted as non-displacement pile that is ...

Increasing efficiency does not necessarily require the use of expensive technologies. Sometimes implementing properly management and engineering principles, employing skilled and efficient manpower, planning appropriately, ...

One of the factors affecting overbreak or slough of the roof and walls of underground stopes, causing unplanned dilution is blast vibration. The amount of damage caused by earth vibration can be measured in terms of peak ...

Selecting a suitable pillar recovery method is one of the most important issues in the room and pillar mining. The main purpose of this study is to compare two methods for pillar recovery in Tabas central coal mine (TCM). ...

Remnant magnetization causes a change in the direction and intensity of the magnetization vector. If inversion is performed regardless of remnance, in some cases it may have unreliable and misleading results. For inversion ...

This paper focuses on some fracture toughness tests performed on the pre-cracked Brazilian specimens of rock-like materials. Also the effect of rock fracture filling on the fracture toughness was considered experimentally.  ...

Slope stability analysis of jointed rocks has been the focus of many studies. The presence of joints and discontinuities in rock environments intensifies instability along with the development of block movements. Many ...
