[0052] The inside of the main box 1 is installed with: a water tank 11, a booster pump 12, a main controller 2, a battery 31 and a distribution valve 7; the main controller 2 is electrically connected to the battery 31 an...
Embodiment 2
[0056] Such as Figure 6 As shown, the directional variable flow hydraulic splitting method in this embodiment is realized by the directional variable flow hydraulic splitting system in the above embodiment, and specifically includes the following steps:
[0057] S1: Path planning, first plan the rock splitting path and the splitting timing of each splitting point according to the construction conditions on site and the direction of the stone falling, and mark it on the rock wall;
[0058] S2: Drilling and data acquisition, the rock wall is drilled with the marking point on the rock wall of the drilling device 4, and the torque of the first motor 45 and the second motor 46 is collected by the secondary controller 47, and the data is collected. It is transmitted to the main controller 2, and the rock formation hardness at each marked point is obtained through the calculation of the main controller 2, and the cracking critical pressure value at the marked point is calculated at ...
