The static rock blasting technology is a novel technology for replacing the traditional explosive blasting. Compared with the traditional explosive, the static blasting has the advantages of high safety, low noise, simple and convenient operation, easy storage, easy transportation and the like.

Static blasting is usually implemented by filling a hole with a static blasting agent or applying a hydraulic rod to apply pressure to the wall of the hole, and when the pressure exceeds the tensile strength of a material to be blasted, the material is broken to realize blasting under the further action of the pressure. For the static blasting agent, the static blasting agent and water are subjected to chemical reaction to generate expansion, the reaction effect is influenced by various factors such as temperature, water quantity and the like, and the blasting speed and the blasting effect are difficult to control. Therefore, the hydraulic rod gradually becomes a main mode of static blasting, the currently used hydraulic rod mainly generates thrust on a rock body through a push block on the hydraulic rod in a hydraulic process, so that cracking is realized, the push block can generate larger thrust through the hydraulic mode, but the action area of the push block and the rock body is relatively larger, and the crack propagation direction is influenced by the drilling stress, but still has certain uncontrollable effect.
