The throwing direction design subsystem comprises (1) surveying the space occurrence and the bedding surface distance of the layered blasting rock mass, analyzing the dominant bedding structure surface and optimizing and designing blasting parameters. In a certain open-air limestone mine, the inclination angle of the rock stratum is 61-77 degrees, and the distance between the main rock strata is 0.3-1.2 m.

1) The resistance of the rock medium to blasting depends on its properties, which are fundamentally determined by its formation conditions, mineral composition// structural architecture and later geological formations. Except for the influence of the later geological construction effect on the unit consumption of explosive, the influence of the rock property on the unit consumption of explosive mainly refers to the influence of the physical and mechanical properties of the rock on the unit consumption of explosive. The types of the rocks are different, the physical and mechanical properties of the rocks are obviously different, and the unit consumption of explosive required by blasting is also obviously different; the volume weight of the rock is increased, the strength and the capacity for resisting the blasting action of the rock are also increased, and the energy consumed for breaking the rock and moving the rock is also increased; generally, as the rock strength factor increases, the specific charge increases.
common types of rocks are coal seams with little gangue, clay, coal seams with much gangue, mudstones, shales, sandstones (argillaceous, siliceous (quartzitic), calcareous), limestone (argillaceous (oolitic or bamboo leaf-shaped), siliceous (dense)), granite (granite conglomerate, coarse-grained granite, medium-grained granite, fine-grained granite), and iron ores (low-grade iron ore, medium-grade iron ore, high-grade iron ore).
2) generally refers to kinds of rocks, as the weathering degree increases, bedding cracks develop more and more, the strength performance of the rocks is greatly reduced, and the unit consumption of explosive required by blasting also obviously decreases.
The weathering degree of the rock and the corresponding mean fracture spacing values are: the average crack spacing of the fully weathered rock is less than or equal to 0.1 m; the average crack spacing of the strongly weathered rock is more than 0.1m and less than or equal to 0.5 m; the average crack spacing of the weakly weathered rock is more than 0.5m and less than or equal to 0.8 m; the average crack spacing of the slightly weathered rock is more than 0.8m and less than or equal to 1.4 m; fresh rock has an average fracture spacing of greater than 1.4 m.
3) is the influence of step height, for medium-length hole step blasting, the larger the step high order is, the stronger the clamping action of the step bottom is, the needed single consumption of explosive will be improved correspondingly.
4) The three factors of explosive explosion are exothermicity, high-speed reaction and large-amount gas generation. The main indexes for measuring the explosion performance of the industrial explosive comprise theoretical demonstrative parameter indexes such as explosion heat, explosion capacity, explosion temperature and explosion pressure, explosion performance indexes such as explosion speed, blast intensity, work capacity and sympathetic explosion distance, safety performance indexes such as thermal inductance, friction sensitivity and impact sensitivity, and environment-friendly indexes such as toxic gas content. The work capacity (explosive force) is the main energy index, and the influence on the unit consumption of the explosive is the largest.
The types of explosives commonly used are:
a. on-site explosive mixing: mixing and loading an emulsion explosive, a porous granular ammonium nitrate fuel oil explosive and a heavy ammonium nitrate fuel oil explosive;
b. packaged explosive (type 2# rock): emulsion explosive, expanded ammonium nitrate explosive, modified ammonium nitrate fuel oil explosive and powdery emulsion explosive.
5) The parameters of the effect of blasting on specific charge consumption can generally be determined by the maximum allowable bulk size (mm) and the loosening or throwing requirements. The loose throw requirement can be subdivided into six types of loose reduction, normal loose, loose reinforcement, throw reduction, normal throw, and throw reinforcement.
specific examples are now given:
