The experimental system for testing the seepage property of crushed rock was designed as shown in Figure 3, which was comprised of four parts: (A) hydraulic pressure system, (B) axial displacement system, (C) permeability system, and (D) data acquisition and analysis system. (A) Hydraulic pressure system was used to provide hydraulic pressure for the specimens.

• Hydraulic fracturing is the use of fluid pressure to create fissures in solid substrate • The gas industry uses ‘fraccing’ to increase the rate and extent of recovery of gas • Gas flows more rapidly & completely through the fracture than through coal or rock Fraccing uses fluid pressure to create cracks for gas and water transport

The 15% crushed limestone mixed with 85% sand indicated a value of good hydraulic conductivity 9.75 × 10 −7 cm/sec but slightly less than the ideal value. The SWCC exhibited a bimodal feature for the bentonite without replacement and tended to be unimodal for the bentonite with TBM material additives.
