Ore resource consumption assessment method based on three-dimensional laser scanning technology

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

technical field [0001] The invention relates to a resource reserve evaluation method in the technical field of mineral mining, in particular to a method for evaluating mineral resource consumption based on the combination of three-dimensional laser scanning technology and geological technology and fully utilizing the advantages of the three-dimensional laser scanning technology. Background technique [0002] A more accurate assessment method of mineral resources consumption is useful for the prediction of deep mineralization in mining areas, the comparative study of mine exploration and mining, the dynamic detection of resource reserves, the acceptance of mining engineering quantities, the management of "three rates" of mines, and the evaluation of the value of mineral resource reserve damage caused by illegal mining The development and effectiveness of such geological work are of great significance. However, due to the difficult and dangerous operating conditions in the min...

Problems solved by technology

However, due to the difficult and dangerous operating conditions in the mining area formed by mining, the abnormally irregular spatial shape of the ore body production range, and the uneven rock-mine interface, the simple geometry of the ore body can be constructed with limited data collected by conventional measuring instruments such as GPSRTK and total stations. Poor shape intuition, low work efficiency, and the assessment results of mineral resource consumption are often very different from the actual consumption. Therefore, it is necessary to scientifically improve the mineral resource consumption assessment method with the help of modern advanced measurement technology
