这是一个在密封、可膨胀的爆炸室内使用丙烷和氧的可控的震源装置。它所产生的能量通过爆炸室的活动底板送入地下,膨胀的爆炸气体与直接按在爆炸室上面的压缩空气簧的惯性成相反的作用力。不需要的二次脉冲(枪拾动gun bounce)被“液压限制器”的机械
This is a controlled source device that uses propane and oxygen in a sealed, swellable explosion cell. The energy it generates is sent to the ground through the moving floor of the explosion chamber and the expanded explosive gas acts in opposition to the inertia of the compressed air spring directly above the explosion chamber. Unnecessary secondary pulse (gun bounce) is the “hydraulic limiter” of the machinery
