Embodiment
[0025] The technical solution of the present invention is: a step blasting teaching demonstration model, such as figure 1 and figure 2 As shown, including the pedestal, the front end of the top of the pedestal is respectively equipped with a blasting network simulation part and a charge simulation part, among which,
[0026] The blasting network simulation part includes a Chevron board, and a number of uniformly distributed small holes are opened on the top of the Chevron board, and LED lights 7 are arranged in the small holes, and the LED lights 7 are fixed on the Chevron board during processing. The wires are all placed under the Chevron board, and the wires are correspondingly connected to a circuit board, on which a row of pins is soldered, and each row of pins represents an LED light 7 for connecting the circuit. The control circuit board is controlled by a single-chip microcomputer. It is also soldered with pin headers. The number is the same as the number of lights on...

The invention discloses a bench blasting teaching demonstration model. The model comprises a base, a blasting network simulation part and a charging simulation part are arranged at the front end of the top of the base, the blasting network simulation part comprises a plate body, small holes which are uniformly distributed are formed in the top of the plate body, and light sources are arranged in the small holes, the charging simulation part comprises a transparent plate body and a transparent pipe, the transparent plate body is provided with an opening, the base is provided with a hole corresponding to the opening in the transparent plate body in position, the transparent pipe penetrates through the opening to be inserted into the base, the part, located at the lower end of the charging simulation part, of the base is transparent, and the transparent pipe is filled with designated materials to simulate blasting materials, the rear end of the top of the base extends upwards along the three side walls of the base to form a boss, the top of the boss is parallel to the top of the base, the gas cylinder is connected with the rear end of the boss, grooves are vertically formed in the front end of the boss side by side, the front end of the boss is connected with a rock simulation part, and the rock simulation part comprises blocks which are stacked to form a trapezoid. According to the invention, a user can understand related knowledge such as explosive charging, wiring, detonation, blasting pile forming process and the like conveniently.
Description
technical field [0001] The invention belongs to the technical field of teaching aided design, in particular to a step blasting teaching demonstration model. Background technique [0002] Because of its obvious superiority in economy and technology, open-pit mining determines that it has a general trend of priority development in the field of mineral resource development. Therefore, all mineral resources that are suitable for open-pit mining should be used first, so open-air step blasting is very important. [0003] Open-air step blasting is currently widely used in engineering projects such as mines, highways, railways, water conservancy and hydropower, etc., and the demand for blasting operators is increasing. Due to relevant safety management regulations, personnel without work permits are not allowed to enter the blasting construction site, so it is difficult to achieve hands-on operations when training such workers. At present, in the teaching of open-air step blasting...
