  • Publication number: 20250154868
    Abstract: An electric-pulse fracturing device for hard roof of coal mine based on a self-sealing water bag and an using method thereof are provided. The device includes a power switch, a charging power supply, a current limiting protection resistor, an energy storage capacitor and a high-voltage electric pulse switch connected in sequence. The energy storage capacitor is connected with an end of a gas gap switch, an other end of the gas gap switch is connected with an assembled self-sealing water bag high-voltage electric pulse electrode structure through a high-voltage cable, and the electrode structure is fixed through an assembly rod. The self-sealing water bag high-voltage electric pulse electrode structure includes a self-sealing water bag and an electrode structure capable of focusing shock wave energy, and the number of the self-sealing water bag high-voltage electric pulse electrode structure depends on fracturing effect.
