- Rock bolting to unstable roof and sidewall areas
- Working with the Mine Manager to Mines Regulations requirements
- Crane operated shaft access and man riding systems, communication, ventilation, lighting, operating and emergency procedures
- Mine haulage and transport including winch & rail systems
- Pumping and placing infill materials in underground stabilisation areas - concrete, foamed concrete, PFA paste, grout and sand
- Constructing barriers and bulkheads to mine galleries from in-situ concrete, grout, blockwork or structural steel to retain infill materials
- Shuttering underground for concrete or grout barriers including propping & dowelling in restricted working space
- Use of geotextiles to prevent grout loss into mine discard and to reinforce stepped grout barriers
- Stowing and placement of sand, aggregates and cement bound stone infill materials using conveyors, pneumatic stowers and mining dragline “slusher” system
- Installation of bat mitigation measures in mine galleries
- Investigation and surveys, working with other specialists - geotechnical consultants, geologists, archaeologists, environmental and radon exposure consultants
