A directionally controlled smooth blasting apparatus as claimed in claim 8, wherein: the storage box (4-3) is welded at the bottom of the annular clamp (4-1), the winding motor (4-4) is arranged on one side of the storage box (4-3), the winding rod (4-5) is rotatably arranged in the storage box (4-3) through a reinforcing shaft, one end of the winding rod is connected with an output shaft of the winding motor (4-4), the connecting cable rope (4-6) is wound on the winding rod (4-5), the spraying rings (4-7) are fixedly connected with the connecting cable rope (4-6), and the spraying rings (4-7) are sequentially connected through a connecting rope.
10. A method of directionally controlled smooth blasting according to any one of claims 1 to 9, comprising the steps of:
the method comprises the steps of firstly, acquiring and simulating data of a tunnel face (5) through various measuring and calculating instruments, wherein the data comprises the size of the tunnel face (5), the rock strength in a tunnel and the like, then carrying out blasting simulation in a simulation system of an intelligent computer, thereby determining various blasting parameters comprising depth parameters of holes to be charged, and determining charging intervals corresponding to the holes according to the depth parameters of the holes;
secondly, debugging and installing equipment, detecting a blasting device and related equipment of detonator explosives to ensure that the equipment is normal, then placing the blasting device on a tunnel face (5), positioning a blasting point by utilizing a bottom calibration bracket (1), a center fixed calibration component (2), a lateral adjustable fixed calibration component (3) and a hanging type longitudinal point position spraying component (4) of the blasting device, and then drilling holes on the blasting point to form a peripheral eyelet (6), a bottom plate eyelet (7), a peripheral auxiliary eyelet (8), a vault auxiliary eyelet (9) and a uniform eyelet (10);
thirdly, arranging and blasting the detonator, striking the detonator at the drilling position, then removing the blasting device, moving personnel to a safe position, controlling the detonator to open, detonating explosive, enabling the generated shock wave and high-temperature and high-pressure gas to act on the eye wall, and enabling rocks around the peripheral eye hole (6), the bottom plate eye hole (7), the peripheral auxiliary eye hole (8), the arch crown auxiliary eye hole (9) and the uniform eye hole (10) to be subjected to strong compression crushing, and meanwhile, the formed compression stress wave is spread in all directions, so that smooth blasting is finally realized.
