Slurry Tunnelling

Excellent water separation is vital to efficient slurry tunneling.

Separation difficulties result in:

• Severe loss of advance rate due to over-weight slurry.
• Equipment wear due to excessive solids in the slurry
• Major expenses in dumping and diluting the slurry

Morrison Mud specialise in centrifugal flocculaton techniques which remove all fines and return clear water to the system.

Equipment sale and hire

Morrison Mud offer complete slurry systems to tunnelling contractors and manufacturers, as well as components and specialised help for designing, specifying and building your own system. Hire equipment including shakers, hydrocyclones, tanks, centrifuges and

flocculation systems are also offered (subject to availability).

Viscosity and Gel Strength

Plain water is generally the best fluid for slurry tunneling in clays. But or difficult conditions such as gravels, cobbles, and open running sands, Morrison Mud use the science of rheology to formulate special slurries - with or without bentonite - which

• Prevent scouring and over-mining
• Resist slurry loss into the ground
• Provide real support for unstable face
• Give very high cuttings loading at lower pump rates
• Prevent s settling out in pipes, pumps and tanks
