Laboratory Controlled Experiments of Rock Fracture and Induced Seismicity

裂缝在自然界中的所有尺度上都很重要，从矿物颗粒微裂缝到构造板块边界。它们制造地震，控制流体流动，并在工程规模上降低地下结构周围岩石的完整性。地震传感器在地球上的记录使地震学家能够创建地球内部结构的详细图像。以类似的方式，可以在受控条件下在实验室中收听小规模的诱导压裂，并使用具有高频传感器的相同地震学技术来对裂缝的生长进行成像，并监测其对岩石变形和流体流动的影响。

Fractures are important at all scales in nature from mineral grain micro-cracks to tectonic plate boundaries. They create earthquakes, control fluid flow and at the engineering scale reduce the integrity of rock around underground structures. The recording of earthquakes on sensors all around the earth has allowed seismologists to create detailed images of the internal structure of the earth. In a similar way, it is possible to listen to small scale induced fracturing in the laboratory under controlled conditions and use the same seismology techniques with high frequency sensors to image the growth of fractures and monitor their effect on rock deformation and fluid flow.
