Example Embodiment

[0029] Generally, in the assessment of mineral resource consumption, it is based on the average thickness of each block in the mining area of ​​the ore body obtained during the exploration and mining stage, and then the limited spatial data projected area obtained by conventional instrument measurement methods to estimate the space volume and ore volume of the block. And the amount of beneficial components, and then calculate the total consumption of mineral resources in the scope of the ore body. Because this method is limited, discontinuous, and uneven in the collection of spatial information of the ore body's utilization range, it cannot fully reflect the ore body's exposed spatial range in the mining stage; in addition, the evaluation method is mainly based on the cross-sectional view and the plane projection map. To proceed, the error is large and time-consuming and laborious. In view of the shortcomings of the prior art, the present invention provides a method for evaluat...

Abstract

The invention discloses an ore resource consumption assessment method based on the three-dimensional laser scanning technology. The method comprises the steps that early-stage preparations are conducted; mining area range space point cloud data is collected and preprocessed; according to the mining area range space point cloud data, an employed ore body morphology model is corrected and built according to the mining area range space point cloud data; a block morphology data model is built through space division of the employed ore body morphology model; a digital surface model is built to estimate the simulated point cloud data distribution corresponding to block sections; the block range space volume is decompose and estimated through the block morphology model; the ore resource consumption in the employed ore body range is assessed. The invention further provides a high-density continuous uniform distribution data point space range limit estimation method and a space point cloud data simulated distribution quadric surface fitting method. The assessment efficiency and the precision of the ore resource consumption are obviously improved.

Description
