In the traditional, the ore tonnage calculation in mine production is based on the Field work recording, which was tested by workers outside about the exploded ore. But the geological boundaries still follow the original geological maps. After blasting, the ore body’s volume will expand and the mine rock boundary lines will also change in spatial .It can not meet the needs of the precise calculation of ore production and guiding the scraping operation. In this paper, we proposed that when calculating the volume of the ore body, we should add some variables which were produced when blasting, and have a research on the geological characteristic of the ore body and express it by mathematical analysis methods. Based on the practical production of the impact of blasting on the ore body, we calculate the coefficient of variation ore, the loose coefficient, the trajectory of spatial displacement of the minerals, and recalculate the three-dimensional mass distribution of the ore after blasting in a loose situation, and then according to these parameters to calculate the shape of ore body. At last, according to the blasting part of the ore body based on measurement and acceptance, we need to recover the present ore body after the blasting, add the blasted part to the ore body in order to join the two parts together, and then we can calculate the volume and the quality distribution of the whole ore body more accurate. It has a significant meaning to explore and research the three-dimension mine blasting technique for utilizing the mine resources．
