The presentation was at the AIG (Australian Institute of Geoscientists) Hydrogeology

Tom Wilson, senior implementation manager at Earth Science Information Systems, presented Groundwater and surface water data management at Rosebery Mine, Tasmania in May 2015 at the AIG Hydrogeology in Mining conference. 

The Conference aims included providing information exchange and awareness raising among the South Australian mining and hydrogeology communities. The Conference programme provided talks covering a range of groundwater fields by industry professionals drawn from mining and energy companies, government bodies and consulting firms.

The Conference was for mining and resource industry staff, providing practical and technical information on groundwater issues. The Conference also benefited hydrogeologists who wished to understand the issues associated with mining.

The Conference programme was designed assuming minimal experience; however, the majority of talks concentrated on specific technical areas. The Conference was suitable for all levels of experience: from new entrants to the industry to experienced practitioners.

Groundwater and Surface Water Data Management at Rosebery Mine, Tasmania

Rosebery is an underground polymetallic base metal mine operated by MMG and is located in the township of Rosebery, Tasmania, approximately 300 north-west of Hobart. It has operated continuously since 1936 with current mine life extending beyond 2020.

Zinc, lead and copper concentrate and gold dore is produced at Rosebery using mechanised underground mining methods and crushing, grinding and flotation processes.

The groundwater flow system comprises a deep fractured aquifer (which contains the mine voids), overlain by surficial glacial deposits and weathered material. Interaction between surface waters and groundwater has been observed across the catchment, with 17% of precipitation infiltrating as groundwater to subsequently be discharged as baseflow into creeks and rivers.

To monitor surface water and groundwater quality at the site, a network of over 60 groundwater monitoring wells and approximately 40 surface water sampling locations have been established. Groundwater monitoring occurs biannually to assess seasonal variability in quality, while surface water monitoring occurs as often as weekly at some locations.

Historical monitoring data extends to 1990, providing a valuable information source to identify long term water quality trends. The historical data set grows with each new monitoring event.

Efficient management of the large monitoring data set is paramount given licence conditions imposed on the mine. Confidence in the data accuracy is crucial in forming the basis for interpretation and subsequent operational decisions.

MMG has adopted an Environmental Data Management System (EDMS) comprising the following ‘off-the-shelf’ components produced and supplied by Earth Science Information Systems:

ESdat LSPECS – a complete field program management system used to generate Sampling and Analysis Quality Plans, manage field program delegation, scheduling and post-field validation as well as all stages of laboratory interaction (including e-quotes, e-COC, e-SRN and laboratory reports)

pLog – a tablet based application that synchronises with LSPECS (via the cloud) allowing complete field data capture, including water levels, field parameters, field observations, sample information and even well logs and construction details

ESdat Desktop – client based software accepting and compiling data from myriad sources, including LSPECS generated and validated field program data, logger data, historical data and environmental standards. ESdat Desktop allows rapid data interrogation and map based querying as well as generation of a wide range of standard reports, such as comparison tables, time series graphs and hydro-chemical plots, such as stiff and piper diagrams.

MMG has implemented the EScIS EDMS with great success, with key benefits including:

  • Centralised on-site storage of all Environmental data in a single SQL data base
  • Easy-to-use and powerful querying of long term historical data to identify trends, generate timely responses to ad-hoc regulator requests or share data with consultants
  • Complete electronic data capture and lab interaction (primary and secondary labs)
  • Real productivity gains, allowing transition of effort from manipulation to interpretation
