This technology aims to accurately control explosive energy release and efficiently break rock mass, which not only significantly improves construction efficiency and safety, but also optimizes blasting effect, reduces explosive consumption and vibration hazards. Therefore, the automatic and accurate design of single-hole charge quantity has become a key link to improve the level of rock mass blasting technology.

[0003] Existing blast hole charge quantity design mainly relies on artificial experience or simplified formula for overall estimation. These methods cannot accurately reflect the complexity caused by the non-uniformity of rock mass and the change of physical and mechanical properties when the blast hole passes through different rock layers, resulting in inaccurate single-hole charge quantity calculation, unstable blasting effect, and serious explosive waste. Although the blasting specific consumption is the core of calculating the single-hole charge quantity, and it is affected by many factors, the existing technology lacks an automatic design method for single-hole charge quantity that can dynamically respond to changes in rock layers. Some attempts to simplify the specific consumption based on rock mass explosibility have not effectively solved the problem of accurate design under complex geological conditions.

[0031] Figure 1 The flowchart of the rock mass blasting hole charge amount design method based on rock mass blastability provided by the embodiments of the present application is shown as Figure 1 The rock mass blasting hole charge amount design method based on rock mass blastability includes steps 110, 120, 130, 140, 150 and 160.

[0032] Step 110, based on exploration data, blasting design and three-dimensional geological modeling technology, a target rock mass model containing blast holes is constructed and relevant attributes are obtained according to coordinate information; In some embodiments, the rock mass blasting hole charge amount design method based on rock mass blastability includes: Based on three-dimensional geological modeling technology, a rock mass model is constructed; Based on the blasting design plan, the rock mass model is cut into a blasting area to obtain coordinate information of the blasting area, and the blast hole is laid out; The coordinate information of the blasting area is corresponded with the exploration data to obtain the attributes of the target rock mass and perform value assignment, the attributes of the target rock mass include lithology, rock density, rock mass longitudinal wave velocity, designed blasting crater condition and blasting block size condition obtained by early exploration; Based on the attributes of the target rock mass, the target rock mass is layered to construct a target rock mass model containing blast holes and related attributes.

[0033] It is easy to understand that based on the three-dimensional geological modeling technology, the rock mass model is constructed, the rock mass model is cut based on the blasting design plan, the blasting hole is laid out, the cut blasting area has geological coordinate information, and then the geological information in the corresponding coordinate interval range is obtained according to the geological coordinate information and combined with the previous geological exploration data, including the properties (which rock type) and density of the rock mass.

[0034] Combined with the exploration data and the three-dimensional geological modeling technology, the coordinate information of the blasting area is corresponded with the exploration data, the properties of the target rock mass are obtained and valued, the density of each layer of rock, the longitudinal wave velocity of the rock mass, the blasting crater condition and the blasting fragmentation condition are determined, the density of the rock is generally obtained in the engineering geological exploration, and the elastic longitudinal wave velocity is valued as the general longitudinal wave velocity of which rock type. Finally, the target rock mass is layered based on the properties of the target rock mass, and the target rock mass model containing the blast hole and the related properties is constructed.

[0035] Step 120, calculating the blastability index of each layer of rock mass; In some embodiments, the calculating the blastability index of each layer of rock mass comprises: Based on the rock density, the longitudinal wave velocity of the rock mass, the blasting crater condition and the blasting fragmentation condition of each layer of rock mass, the blastability index of each layer of rock mass is obtained through the rock mass blastability index calculation formula, and the rock mass blastability index calculation formula is as follows:

[0036] Among them, is the volume of the rock mass blasting crater in the design requirement, , , The large block rate, the small block rate and the average qualified rate of the blasting crater in the design requirement respectively, is the rock density in exploration, is the rock mass elastic longitudinal wave velocity corresponding to the rock type, N is the rock mass blastability index.

[0037] It is easy to understand that the rock mass blastability comprehensively reflects the difficulty of the rock mass to resist the blasting and crushing of explosives, which is mainly determined by the physical and mechanical properties of the rock mass and the geological structure of the rock mass.

[0038] For example, the large block rate of the blasting crater is greater than 700mm, the small block rate is less than or equal to 100mm, and the average qualified rate is 200~700mm.

[0039] Step 130, determining the unit consumption of each layer of rock mass according to the blastability index; In some embodiments, the determining the unit consumption of each layer of rock mass according to the blastability index comprises: Based on the explosibility index, the blasting classification, the explosibility degree and the unit consumption of each rock mass are determined.

[0040] Table 1 is a table of the relationship between the explosibility index and the explosive unit consumption provided by the embodiments of the present application. As shown in Table 1, the rock mass explosibility is divided into 5 levels. The explosive unit consumption of open blasting is smaller than that of underground blasting. The specific case can be determined by comprehensively judging the range of the unit consumption corresponding to each explosibility index in combination with the rock mass and geological conditions of the site construction.

[0041] Table 1 Relationship between explosibility index and explosive unit consumption

[0042] When the explosibility index is obtained, the corresponding unit consumption value is obtained by using the linear value method according to Table 1. The linear value calculation formula is as follows:

[0043] Among them, , , , respectively represent the minimum and maximum rock mass explosibility index, the minimum and maximum unit consumption of the interval, is the unit consumption value, is the explosibility index.

[0044] Step 140, determining the length of the blast hole in each rock layer in the target rock mass model; In some embodiments, the determination of the length of the blast hole in each rock layer in the target rock mass model comprises: Obtaining the left intersection point and the right intersection point of the blast hole path at the interface of different rock layers in the target rock mass model; Based on the left intersection point and the right intersection point, the intersection center value is obtained; Based on the intersection center value distance of the interface of different rock layers in the three-dimensional model, the length of the blast hole in each rock layer is obtained.

[0045] Figure 2 is a structural schematic diagram of the rock mass layering provided by the embodiments of the present application, as Figure 2 shown, - Different rock layers are shown. There can be different rock layers in one blasting area. Each rock layer can have different lithology, rock density, etc.

[0046] Further, according to the geological model, the rock layer situation and the length of the blast hole are determined. The explosibility, unit consumption and other information of each rock layer are recorded. According to the intersection point of each rock layer and the blast hole path in the three-dimensional geological model, the length of the blast hole passing through each rock layer is determined. For the contour hole such as the presplit hole or the smooth hole, the unit consumption at this time represents the linear charge density.

[0047] It should be noted that the blast hole is divided into profile hole (including presplit hole and smooth hole), buffer hole and main blast hole.

[0048] Step 150, calculating the average unit consumption of the blast hole; In some embodiments, the calculating the average unit consumption of the blast hole comprises: When the type of the blast hole is the profile hole, at this time the unit consumption is the linear density of explosive, the average linear density of explosive of the profile hole is calculated based on the length of each rock layer by the following formula:

[0049] Wherein, is the average linear density of explosive of the profile hole, is the linear density of explosive, is the length of the profile hole corresponding to the rock layer, i is the total number of layers of the rock mass; n When the type of the blast hole is the buffer hole or the main blast hole, the average unit consumption of the buffer hole or the main blast hole is calculated based on the length of each rock layer by the following formula: Wherein,

[0050] is the average unit consumption of the buffer hole or the main blast hole, is the unit consumption of the rock layer, is the length of the buffer hole or the main blast hole corresponding to the rock layer, i is the total number of layers of the rock mass. i When the type of the blast hole is the buffer hole or the main blast hole, the average unit consumption of the buffer hole or the main blast hole is calculated based on the length of each rock layer by the following formula: n

[0051] Step 160, obtaining the target charge amount of the blast hole based on the average unit consumption.

[0052] In some embodiments, the obtaining the target charge amount of the blast hole based on the average unit consumption comprises: When the type of the blast hole is the profile hole, the target charge amount of the blast hole is obtained based on the length of the profile hole and the average linear density of explosive; When the type of the blast hole is the buffer hole or the main blast hole, the target charge amount of the blast hole is obtained based on the volume occupied by the buffer hole or the main blast hole and the average unit consumption.

[0053] It is easy to understand that when the type of the blast hole is the profile hole, the target charge amount of the blast hole is obtained based on the length of the profile hole and the average linear density of explosive, and the calculation formula is as follows:

[0054] Wherein, L is the length of the profile hole, ​​The target charge amount of the profile hole is determined.

[0055] When the type of the hole is a buffer hole or a main blast hole, the target charge amount of the hole is determined based on the volume occupied by the buffer hole or the main blast hole and the average specific consumption, and the calculation formula is as follows:

[0056] wherein, a is the spacing of the holes, b is the row spacing of the holes, H is the height of the step, V is the volume of the hole, Q is the target charge amount of the buffer hole or the main blast hole.

[0057] According to the rock mass blast hole charge amount design method based on rock mass explosibility provided in the embodiments of the present application, the attribute value of the target rock mass is obtained by acquiring the point cloud data of the target rock mass and performing three-dimensional model construction and blast area cutting, the specific consumption range is determined in combination with the explosibility index of the target rock mass, the length of each rock layer is calculated based on the intersection of each rock layer and the hole path in the three-dimensional model, the average specific consumption of the hole is calculated based on the length of each rock layer, and finally the target charge amount of the hole is obtained according to the average specific consumption. By obtaining the corresponding specific consumption according to the explosibility index of the rock mass, the average value of the specific consumption is calculated according to the explosibility of different rock layers to further design a reasonable single-hole charge amount, thereby reducing the problems of waste or poor blasting effect caused by improper charging. By reasonably determining the hole charge amount, the blasting effect can be maximized, automatic design of the single-hole charge amount based on the rock mass explosibility index is realized, the attribute differences of different rock layers are considered, the average explosive specific consumption is determined, and the design result of the charge amount is more objective and reasonable.
