  • Supercritical fluid drilling and blasting integrated double-arm drill jumbo and control method thereof
    Patent number: 11634986
    Abstract: A control method of a drill jumbo is provided. The drill jumbo includes a pre-splitting arm, a drill arm, and a chamber. The pre-splitting arm includes a positioning device, a fixing buckle, a longer rod, an electric telescopic rod, and a water injection opening. The chamber includes a constant pressure valve, an excitation circuit, and a port. A computer controls the positioning device to perform positioning, afterwards, the fixing buckle is opened, the telescopic rod is started, the longer rod is jacked into a position in the hole, and oil is injected into a hydraulic expansion capsule. After blocking of the hole is completed, water is injected into the water injection opening. The port is opened to inject a mixed-phase fluid. The port is closed, the excitation circuit is started, and after a pressure rises to a set value, the constant pressure valve is opened.
