The Mining Remediation Authority requires a framework agreement for the provision of services relating to the construction and rehabilitation of boreholes in former mining areas to support the objective to understand water levels and chemistry. The services are anticipated to include borehole drilling, construction, maintenance, cleaning, rehabilitation and associated works/services. The drilling will be predominately coal measures and overlying strata including regionally important aquifers (may need casing off). The targets will often be specific mining features, both void and collapsed. Drilling may be required in areas where multiple sets of workings are present which may create challenges. Targets and strata above and in the zone of influence of workings may be collapsed and/or fractured due to the effects of mining. Accuracy and verticality of borehole drilling will be of high importance as targets are often small and at many hundreds of metres depth. The future survey/sampling/pumping requirements for the boreholes makes verticality important for both targeting of underground features and their operational purpose.
