GROUND SUPPORT & ROCK REINFORCEMENT
MasterLifeSF100 and MasterLife300D are watersoluble bags easily added when adding the fibres . And overall it is a more cost-effective solution compared to post-excavation grouting / rehabilitation work .
GHH ' s roof & ground support offer
GHH Group offers a wide range of equipment to provide secure roof and ground support . This includes through Mine Master roof bolters , roof scalers and customised , dedicated solutions to support customer ’ s specific ground conditions and application needs . GHH also has dedicated shotcrete machines in both the articulated and rigid chassis variations as well as front basket boom machines to support the operations .
Starting with the Roof Scaler 2.0 SB , this is a turnkey , custom designed machine for a mine in Zimbabwe , with a tramming height of less than 2 m . This machine was designed with the purpose of controlling the condition of the hanging wall - carrying out roof inspection and roof scaling . The RS 2.0 SB has one boom with an inspection basket ( with FOPS certified canopy ) allowing two people to be lifted to a height of 6.2 m to visually check the condition of the hanging wall . The second boom has a powerful hydraulic breaker to remove broken fractions , preventing uncontrolled rock fall . Operation of the booms can be either done using diesel engine or electric network depending on the conditions and service supply

availability . The hydraulic breaker can be controlled safely from the FOPs certified operator ’ s compartment or from outside of the machine via wireless control panel – in this scenario the operator needs to be in a safe zone guarded by laser barrier . The machine also comes with a collision avoidance system interface and overspeed control system - a proven solution for increasing safety during tramming . On top of that RS 2.0SB has four wide angle cameras and a ‘ black box ’ to record all footage .
In co-operation with long time partner J . H . Fletcher and strategic mining customer KGHM in Poland , Mine Master developed , and successively implemented , the Roof Scaler 3230-AD , in a KGHM salt mine . The machine is able to mechanically remove loose material from the hanging walls / side walls / foot wall , with a reach of up to 9 m in height and 0.5 m below ground level . The machine can work with a drum cutter as well as with a pick , to conduct scaling in a safe way . There is already a remote control option installed , whereby the machine can be operated from outside the cab .
A powerful cutter head allows for performing these tasks in rock salt , where other scaling systems , like hydraulic breakers , cannot be applied . The specific formation of the rock salt deposit does not allow for any vibrations during scaling .
Another customised solution from Mine Master is the SWOI 1.4 or SWOI 1.7 , an auxiliary machine designed to place temporary hydraulic props , which work as additional roof support . It inserts the prop between the roof and the floor
