• Constructing new access shafts onto workings
• Propping and cogging to unstable mine roof areas
• Rock bolting to unstable roof and sidewall areas
• Working with the Mine Manager to MASHAM 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
• Install bat mitigation measures in mine galleries
• Investigation and surveys, working with other specialists - geotechnical consultants, geologists, archaeologists, environmental and radon exposure consultants
• The mines being filled are often beneath residential property or ecologically sensitive areas requiring close liaison with residents and other stakeholders
