Slope stability analysis forms an integral part of the opencast mining operations during the life cycle of the project. In Indian mining conditions, slope design guidelines are yet to be formulated for different types of mining practices and there is a growing need to develop such guidelines for maintaining safety and productivity.

To quickly and effectively determine the coal mine slope stability, this paper establishes a prediction model using the random forest algorithm. Six factors influencing the slop stability were selected as input of the prediction model, including the gravity density of rocks, cohesive force, internal friction angle, slope angle, slope height and ...

The Indian Coal Mining Industry is moving towards deeper opencast mines upto a depth of around 500m like Manuguru OC-II Extension and RG OC-II extension. In India, Lot of accidents have been occurred due to highwall slope failure (table 1.1). These slope failure accidents in Indian mines have taken place due lack of sound design of slopes

Memories of a WV Coal Miner. In 1972, at the age of 22, I completed a twelve-week mining course at Sharples and graduated with a 95 % average. As much as I tried though, I couldn't get anyone to hire me because of no underground experience. The Pittston mining office was almost directly across the river from our house, so I took advantage of ...

The results of field forensic investigation, laboratory physical model test, and numerical simulation show that the mining of the M16 coal seam exerts little disturbance to the mountain, while the mining of the M10 and M14 coal seams is the main external cause of landslide and collapse and the mining of M14 coal seam finally unleashes the collapse.
