Abstract: The development of fissures in water-rich burnt rock pose a serious threat to the safe production and slope stability of open-pit mines.In order to determine the width of the water resistant coal rock column on the high slope of the burnt rock in open-pit mines, the northern slope of a certain open-pit mine in Changji, Xinjiang was taken as a research object.By constructing a mechanical model of a hump distribution for excavation and unloading of the slope, the unloading and relaxation area of t... More
