Problems solved by technology
This method mainly relies on manual map reading and judgment. Especially in the edge area, it is difficult to clearly define the change point of the ore body thickness, resulting in an error between the given number of blasting unit layers and the actual one, which affects the determination of the ore recovery rate. Full recycling of resources

Embodiment Construction
[0026] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0027] Taking the ore body of Meishan Iron Mine as an example, through the present invention, the stratification of the mining blasting unit body is judged and the stratification number is stored and recorded, such as Figure 7 As shown, the specific steps include:
[0028] (1) Ore body modeling: In the Surpac software, the boundaries of each layered ore body are connected independently to form their own independent surfaces, and layer-by-layer independent ore body surface entities are established, such as figure 2 shown;
[0029] (2) Obtain the number of ore layers: drag the ore body surface of each layer built in step (1) and the roadway entity to build the b...

The invention provides a method for layer judgment and layer number storage and recording of a mining blasting unit body. The method specifically comprises the following steps of carrying out ore body modeling, and building layers of independent ore body surface entities; obtaining the number of seams, cutting a stoping drift section required for modeling of the blasting unit body and obtaining the number of the seam at which the current layer is located; and writing attribute description values, namely generating a blasting unit entity, writing the number of the seam into attribute description fields of the blasting unit entity and a contour line. The method provided by the invention can obtain the ore source condition of the upper part of the current blasting unit body under the condition of not needing an ore body plane graph and various layered ore body profiles of the position at which the blasting unit body is located, so that the work efficiency and the accuracy for obtaining information are greatly improved; fine management on resources in mining production is achieved by data; and a detailed data basis is provided for fine management in the mining production process.
Description
technical field [0001] The invention belongs to the field of underground mine mining technology and computer three-dimensional modeling technology, and in particular relates to a method for judging the layers of a mining blasting unit body and storing and recording the number of layers. Background technique [0002] Underground mine blasting unit is the most important object and means of mining production and mine resource reserve management. For underground mines mined in sections, counting from the first layer, the blasting unit is located in which layer, and the condition of the upper layer ore body directly affects the mining design of the ore body and the recovery of ore resources. [0003] Such as figure 1 As shown, the blasting unit body is constrained by two upper and lower sections and three layered diamond-shaped mining tunnels. In the thick and large ore body area, in addition to the three layers constituting the blasting unit, there may be multiple layers of or...
