Dynamic slope stability in open-pit mines still remains a challenging task in the computational mining design. Earthquake and blasting are two significant sources of dynamic loads that can cause many damages to open-pit mines in active seismic areas and during exploitation cycles. In this work, the effects of earthquake and blasting on the stability of the NW slope of Chadormalu mine are compar...

one of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. after choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could be economically impossible. choosing a mining method depends on the geological and geometrical c...

In recent years, there has been a decline in the efficiency of coal mining by traditional methods. On one hand, volume outside contour cut, which is economically impractical for open-pit mining, increasing. other when using underground geotechnology, cost production exceeds performing operations open this due to differences factors operation pit and mine. This circumstance determines use open-u...

Original scientific paper Evaluating the deterioration of ecological environment and vegetation of coalfields caused by China’s large-scale coal mining activities is important because of the fragile ecological environment and low temperature in cold and arid areas. This study takes the open coal pits of Haizhou, Gulianhe, and Huolinhe as examples and proposes a method for evaluating their ecolo...

Abstract Rock bolts have been used in the mining industry for a long time. They are as reinforcement tendons to keep stability of openings underground and slope open-pit mining.
