The primary objective of mine safety monitoring is the swift identification and proactive management of safety concerns and potential disaster risks within mining operations. This goal is pursued to enable the timely implementation of appropriate measures aimed at both preventing and responding effectively to any accidents that may arise. This comprehensive approach hinges on the utilization of diverse technical methodologies to collect, analyze, and continuously monitor data derived from the mining environment.

Project Background

In a competitive bid for a copper mine safety monitoring system in Serbia, Hi-Target was selected as the contractor for a comprehensive online monitoring solution. This achievement followed meticulous assessment and led to deploying GNSS high-precision devices. The realization of this environmentally conscious and technologically advanced mine marks a significant milestone. Hi-Target played a key role in establishing Serbia’s first green, digital mine, a significant milestone that supports the nation’s sustainable economic growth. This underscores Hi-Target’s commitment to innovation and contributing to Serbia’s prosperity.

Pain Point Analysis

Hi-Target encountered its initial hurdle in meeting a demanding schedule, necessitating the prompt setup of survey stations within a tight timeframe while ensuring precision and uninterrupted monitoring functionality. The subsequent challenge involved navigating the intricate mining environment, encompassing a multitude of points and potential signal interference due to nearby metal ores affecting GNSS Receiver reception. Lastly, terrain constraints posed a final obstacle, offering limited space for device installation due to the challenging topography.

Implementation Program

The Hi-Target compact all-in-one MS401 GNSS receiver is distinguished by its exceptional performance and unwavering stability. Housing a Linux operating system, a high-performance positioning board, an antenna, MEMS sensor, and a range of 4G modules, it facilitates vital functions such as MEMS decoding integration, remote control, diverse configuration modes, intelligent communication, and more. The device’s straightforward, compact structure is complemented by features like effortless installation, an IP68 protection rating, and remarkably low power consumption. This amalgamation of attributes renders it eminently suitable for a spectrum of applications, including geohazard monitoring, mining, reservoir management, slope assessment, bridge analysis, and beyond.

Workflow

The intricacies of the project’s survey area posed significant construction challenges, and Hi-Target’s compact all-in-one GNSS receiver proved to be an ideal fit for this monitoring scenario.
Initially, technicians conduct a site survey to identify a stable location beyond the survey area’s boundaries for erecting a GNSS Receiver base station. This strategic placement ensures heightened precision in positioning and capturing displacements for the monitoring stations within the survey area.
Within the survey area itself, technicians establish monitoring stations at each significant feature. These stations are streamlined, comprising just a pole, a solar panel, and an all-in-one GNSS receiver atop. This simplified setup eliminates the need for intricate construction processes or cumbersome transportation methods.

The system achieves real-time collection, transmission, calculation, and analysis of critical operational data from key segments of mine slopes. It captures absolute slope displacement data, enabling a real-time assessment of overall quarry slope safety. This effort establishes a comprehensive deformation monitoring network. By organizing and analyzing this data, the system offers real-time forecasts and early warnings.

Furthermore, the platform visually presents the historical progression and current status of each monitoring and surveillance dataset. This interface provides an uncomplicated, lucid, and efficient point of reference for mine safety management personnel. In the event of an emergency, the system promptly issues warning notifications through various channels, such as audible alarms, animated screen alerts, monitoring screen prompts, and tiered notifications via text message or email to pertinent management and supervisory staff.
