Abstract
High-intensity electric shock (HES) is a new type of fracturing technology that uses electrical energy as a driver. Self-developed ultrahigh-power HES equipment is used to fracture rocks, which is to study the fracturing mechanism of HES. Strain curves of rock fracture processes and ultradeep field images of rock sections are used to analyze the force characteristics and fracturing process of rocks. The rock fracture process is subjected to intense strains with values exceeding 100,000. The generation of strains is related to tensile and shear stresses. The rock section mainly exhibits a tensile section texture. The main cause of rock fracture is the extension of fractures due to the destruction of grain boundaries and intergranular structures. The significance of the above findings is a clearer explanation of the rock-breaking mechanism of the HES.
期刊介绍:
Energy & Fuels publishes reports of research in the technical area defined by the intersection of the disciplines of chemistry and chemical engineering and the application domain of non-nuclear energy and fuels. This includes research directed at the formation of, exploration for, and production of fossil fuels and biomass; the properties and structure or molecular composition of both raw fuels and refined products; the chemistry involved in the processing and utilization of fuels; fuel cells and their applications; and the analytical and instrumental techniques used in investigations of the foregoing areas.
