高强电爆震是一种新型的致裂技术，可以高效改造煤岩层结构，提升煤层气开采效率并增加清洁能源占比，助力实现“双碳”目标；通过改变电压研究了高强电爆震在16 kV和204 μF的条件下致裂长庆岩石的冲击波能量特性。试验结果表明：电压的增加导致电压曲线波前时间下降，下降速率随着电压的上升而降低，这造成电压波形幅度和高强电爆震放电功率的增加，并提升冲击波强度；最大值冲击波振动速度方向为水平从岩石内表面向岩石外表面，为振动的主要传播方向；冲击波的振动能量的主频为0~10 Hz，能量主要分布范围为0~1 000 Hz；电压的提升使冲击波频谱的峰值振幅增加和振动曲线的峰值粒子速度增加，电压的提升使冲击波产生更强的瞬时力，并加速岩石内部结构向不稳定转化。

High strength electric detonation is a new type of fracturing technology that can efficiently reconstruct coal and rock layers structure, improve the efficiency of coalbed methane mining, increase the proportion of clean energy, and help achieve the “dual carbon” goal; the shock wave energy characteristics of Changqing rock induced by high intensity electric detonation under 16 kV and 204 μF conditions were studied by changing the voltage. The experimental results show that the increase of voltage leads to a decrease in the wavefront time of the voltage curve, and the decrease rate decreases with the increase of voltage, which leads to the increase of the amplitude of voltage wave pattern and the discharge power of high-strength electric detonation, and the increase of shock wave intensity; the direction of maximum shock wave vibration velocity is horizontally from the inner surface of the rock to the outer surface of the rock, which is the main propagation direction of vibration; the main frequency of the vibration energy of shock wave is 0-10 Hz, and the energy is mainly distributed in the range of 0-1 000 Hz; the increase in voltage increases the peak amplitude of the shock wave spectrum and the peak particle velocity of the vibration curve. The increase of voltage makes the shock wave produce stronger instantaneous force, and accelerates the transformation of rock internal structure to instability.
