Accurate Survey Data for Safe and Efficient Mining Operations

MCS Surveyors provide professional open pit mine surveys to support safe, efficient, and compliant mining operations. Whether you are managing a large-scale mining site or conducting smaller open cut extraction works, our team delivers precise survey data essential for planning, monitoring, and reporting throughout the mining lifecycle.

With over 30 years of experience in civil and infrastructure surveying, MCS Surveyors is a trusted partner to mining contractors, site managers, and resource developers across Sydney and regional New South Wales.

What Is An Open Pit Mine Survey?

An open pit mine survey involves the measurement, mapping, and analysis of open cut mining sites. These surveys are essential for maintaining operational accuracy, safety, and compliance across all stages of the project, from initial site preparation to final rehabilitation.

Using advanced equipment and techniques, surveyors collect and process spatial data that supports:

Volume calculations for cut and fill or material extraction
Bench design and slope stability assessments
Surface movement and deformation monitoring
Equipment positioning and guidance
Compliance with design models and safety standards

Survey data allows site managers and engineers to make informed decisions, optimise production, and ensure adherence to operational and regulatory requirements.

Technology We Use

At MCS Surveyors, we use the latest surveying technology to ensure high accuracy, repeatability, and efficiency across all mining sites. Depending on the site conditions and the stage of the project, we employ:

Total stations for precise angular and distance measurements
GNSS/GPS equipment for rapid position acquisition across large areas
Aerial drone surveys for fast, high-resolution mapping of complex terrain
Laser scanning for detailed surface modelling and volume assessment

All data is processed using industry-standard software to generate outputs including 3D models, contour plans, digital terrain models (DTMs), and volume reports suitable for engineering, planning, and operational use.

Initial site surveys and baseline mapping

Before mining begins, we carry out topographic and feature surveys to document the existing terrain. This forms the base for mine planning, design modelling, and environmental assessments.

Set out and alignment surveys

We mark out design features such as pit walls, haul roads, drainage systems, and working zones to ensure that excavation works follow planned alignments and safety parameters.

Bench and slope monitoring

We regularly monitor bench levels and slope angles to assess wall stability and ensure that mining works remain within safe and approved tolerances.

Volume calculations and stockpile surveys

Using drone photogrammetry, total station, or GPS methods, we calculate volumes of overburden, waste, and extracted material to assist with reporting, reconciliation, and project costing.

End of month (EOM) surveys

We provide accurate end of month reporting surveys for tracking material movement, measuring productivity, and verifying quantities for contractors and stakeholders.

Deformation and subsidence monitoring

Our team can install and monitor control points around the site to detect movement and ground deformation, helping prevent safety incidents and infrastructure damage.

Why Are Open Pit Mine Surveys Important?

Open pit mining projects require ongoing surveying to ensure excavation is accurate, safe, and economically viable. Mistakes in alignment or volume estimation can result in wasted resources, increased operating costs, or regulatory breaches.

Reliable mine surveys allow project managers to:

Maintain strict compliance with safety and environmental regulations
Track material movement and manage resources efficiently
Make informed design or excavation adjustments based on real-time data
Monitor site stability and prevent slope failure or ground movement
Document site progress for contractors, investors, and reporting obligations

Whether you are starting a new pit, expanding operations, or closing a site, accurate survey data is essential at every stage.
