The volume of the three dimensions for surrounding, n-1 is the maximum series of the dam body of the Tailings Dam, and Vol (Pn) is the top dam body shape
Into the volume of three dimensions that is surrounded of reservoir area and initial land form surface.
It is understood that the storage capacity of Tailings Dam can be (high in certain absolute altitude approximately through calculating in the range of Tailings Dam
Journey) under volume obtain, and this volume size is related to the landform situation in the range of Tailings Dam.Based on DEM terrain datas, profit
With analysis by measure instrument (filling out excavation instrument), need to carry out the scope of volume calculations along Tailings Dam boundary mapping, and be input into meter
Absolute altitude is calculated, the volume in the range of this under absolute altitude just can be calculated.The absolute altitude of input if the crest elevation of Tailings Dam design,
Just can be evaluated whether the design storage capacity of Tailings Dam；If input is the current crest elevation of Tailings Dam, Tailings Dam is just can be evaluated whether
Current full storage capacity.Because tailings warehouse dam body is typically a point step piling up step by step, in order to improve the precision of calculating, then a point platform is needed
Rank step-by-step calculation storage capacity and it is cumulative obtain aggregate storage capacity, and the calculating absolute altitude of dam bodys at different levels is correspondence dam body during point step step-by-step calculation
Crest elevation.
The computational methods of the aggregate storage capacity of the Tailings Dam are still illustrated by taking the Tailings Dam shown in Fig. 2 as an example, the Tailings Dam shown in Fig. 2
Aggregate storage capacity be 8 dam body surfaces to the volume sum between initial land form surface, along with described top dam body is formed
Reservoir area to initial land form surface volume sum, i.e.,：Wherein, Vol (Pi) (i=0,1 ..., n-1) is the
In the range of the i grades of volume of dam body Pi, as i-stage dam body Pi, to build preceding initial land form surface as filling datum level, with H (i+
1) be fill absolute altitude packed space；Vol (P8) is in the range of the reservoir area that the top dam body is formed, to build preceding initial land form
Surface is filling datum level, take H8 as the packed space for filling absolute altitude.
