摘要：
A new method of fracture controlled blasting was put forward using different coupling (water and gas) within the hole at the same time. The paper studies the pressure of hole wall about the hydraulic pressure blasting and gas decoupling blasting by system experiment, and compares the strain with damage on different medium directions after blasting, which reflected the suffering force and distortion of medium. The blasting method can control the process of energy releasing and direction effectively, which makes it possible to destroy one side of the wall rock and protect the other side at the same time.
