However, the hydraulic pressure had a different influence on the uniaxial compressive strength of samples with flaws at different inclination angles. Moreover, three new types of crack were observed: One was a tensile crack, and the others were lateral cracks that emerged in samples under hydraulic pressure.

Hydraulic Fracturing of Rock Formations Part 1: …

 · Hydraulic fracturing involves pumping water and sand at high pressure into gas or oil-bearing rock to fracture it and open pathways for the gas or oil to escape to the receiving well. This is far removed from the mid-nineteenth century practice of ''shooting'' a well, which used explosives instead of water, but the principle is the same.
