【摘要】：介绍了一种基于高压电脉冲的煤体增透实验台,详细地描述了实验台的工作原理和各组成系统的功能特性。该实验台由高压脉冲电源、脉冲放电装置、脉冲水激波传递管道、刚性三轴压力室4部分组成,可模拟10 MPa水压、500 m深度原岩应力下的煤体试样钻孔环境,并在此环境下实现最高15 k V的放电实验。该实验台可完成高压电脉冲水激波衰减特性实验、原岩应力下的煤体静态水压致裂实验、原岩应力下的煤体高压电脉冲水压致裂实验等多项研究工作,为高压电脉冲用于煤体增透的应用研究,提供了硬件支持。
[Abstract]:This paper introduces a kind of coal body antireflection test bench based on high voltage electric pulse, and describes the working principle of the test bench and the functional characteristics of each component system in detail. The test bench consists of a high voltage pulse power supply, a pulse discharge device, a pulsed water shock wave transfer pipeline and a rigid triaxial pressure chamber. It can simulate the drilling environment of coal samples under the original rock stress of 10 MPa water pressure. The discharge experiments of up to 15 kV are carried out in this environment. The experiment bench can be used to study the attenuation characteristics of high voltage electric pulse water shock wave, static water pressure fracturing experiment of coal body under original rock stress and high pressure electric pulse water pressure induced fracture experiment of coal body under original rock stress, etc. It provides the hardware support for the application of high voltage electric pulse in the research of coal antireflection.
