摘　　要：阐述了不同矿区及同一矿床不同地段的河流冲积砂金矿床底板坡度的特征 ,以矿区实例说明了由于存在底板坡度 ,故采金船选用不同的开采路线时 ,采池水的渗漏量相差较悬殊 。It describes the features of floor slope of alluvial sunstone/aventurine mine in different ore areas and the different sections of the same ore mine.An example of the ore area is given to illustrate that the penetration amount of the mining ponds,with big difference,has great impacts on the mining due to the floor slope of the mine when different mining routines are selected for gold dredger.
