Benefits of technology

This patented technology allows operators to efficiently perform various tasks while maintaining their safety during excavations without requiring specific skill levels or technical means such as explosions or hydrants. Additionally, it provides efficient ways to demolish rocks underground at shallow depths where there may have insufficient ground support due to lack of adequate soil conditions like clay mineral deposits.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the efficiency and effectiveness of explosion prevention systems without damaging their surroundings. Current solutions involve either reducing risks associated with blasts themselves or requiring expensive tools like drilling machines. Non-sparking techniques offer potential benefits over current methods because they don’t require dangerous substances like flamane, nitrogen hexavalanche charge propellants, and ammonia. They provide technical means to improve blast resistance performance and safety concerns at sites where large amounts of potentially harmful particles exist.

Abstract

The invention discloses a high-strength rock splitting method and a splitting device based on a weak surface, A method for split comprises that step of: measuring the position parameter and size parameter of high strength rock, measuring the strength of high strength rock coring to obtain rock strength distribution data based on position parameters, determining at least one weak surface of the rock based on the rock strength distribution data, expanding At least one of that weak surface to form a generally elongate groove, wherein the sidewall of the strip sidewall of the groove has a low strength is an air-facing surface, the rock breaking direction is perpendicular to the air-facing surface and points to the air-facing surface, the rock-breaking holes are arranged in vertical rows alongthe rock-breaking direction, wherein, the hole depth, the hole spacing and the row spacing are determined based on the size parameter and the rock strength distribution data, the down-the-hole drill perforates the rock breaking hole based on the rock breaking hole position, inserting the monopolar rock breaking pillar into the rock breaking hole and the rock breaking pole axis faces the face surface, and the hydraulic pressure pushes the rock breaking pole axis to split the rock mass to be broken between the face surface and the rock breaking hole.
