contents	We use a true-triaxial apparatus to monitor hydraulic fracturing in the laboratorial Hot Dry Rock reservoir environment. The borehole injection and propagate fractures are in 300×300×300 mm3 heated granite specimens under triaxial confining pressures. The granite specimens can be heated to 60-120 degrees Celsius. We use pressures to record the triaxial stress and hydraulic fracturing pressures. Every 10 seconds, the data are recorded. The data reflect the variation of hydraulic fracturing with time.
