An improved GreenAmpt model for rainfall infiltration in the inner

Nov 15, 2021 Due to the characteristics of large reserves, loose structure and low strength, an inner dumping site in the open pit coal mine is prone to erosion or overall instability under the rainfall conditions The analysis of rainfall infiltration is quite important to estimate the stability of a dump The inner dump of the Yuanbaoshan open pit coal mine is taken as The Rock Hawg version of the 1150 EVO model has been designed for continuous surface mining; its 10’6” (320 cm) wide drum is employed in bulkexcavations projects, openpit quarries and mining 1150 EVO allow vertical walls and square corners cutting, thanks to the rear mounted drum larger than the tracks Elevating cab, hydraulic 1150 EVO TesmecIn order to scientifically evaluate frozen rock slope stability and keep slope safe with suitable technology in openpit coal mine, and the changing law of physical and mechanical parameters are analyzed The results show that the mechanical parameters increase while the rock is frozen, but the rock strength decreases after freezing and thawing cycles Medium characteristics and stability of frozen rock (soil) slope in
