Abstract

Advancement of wave action stimulation and cross-well seismic imaging in mineral mining governs the need for downhole sources of elastic vibrations. The presented periodic electromagnetic seismic source is equipped with a mechanical–hydraulic drive for fixturing in a hole and for impulse transition to rock, and an electromagnetic impactor for pressure pulse generation. This article presents the experimental studies into the operation of the seismic source of three structural layouts. The features of the operation are discussed. The supply voltage dependences of the main parameters of the seismic source are obtained, and the practical application recommendations are formulated.

井下周期性电磁震源设计

摘要

在矿物开采中，波浪作用刺激和井间地震成像的发展决定了井下弹性振动源的需求。提出的周期性电磁地震源配备有用于固定在孔中并冲动过渡到岩石的机械液压驱动器，以及用于产生压力脉冲的电磁冲击器。本文介绍了对三种结构布局的震源运行的实验研究。讨论了操作的特征。得到了震源主要参数的供电电压依赖性，并提出了实际应用建议。
