The CabSafe Solution

Monitoring Air Quality in Mining Operations

Introduction

Mining operations are crucial in meeting global resource demands but come with environmental challenges, particularly concerning air quality. Particulate matter, specifically PM2.5, emitted during mining activities poses a significant health risk to workers and nearby communities. This blog post will delve into the health risks associated with PM2.5 exposure and introduce an innovative solution, CabSafe, designed to monitor and mitigate these emissions effectively

Health Risks of PM2.5 Exposure

PM2.5 refers to particulate matter with a diameter of 2.5 micrometres or smaller, which can penetrate deep into the respiratory system when inhaled. The health risks associated with PM2.5 exposure are well-documented and include:

Respiratory Issues: Inhaling PM2.5 can lead to respiratory problems such as asthma, bronchitis, and exacerbation of existing lung conditions.

Cardiovascular Effects: PM2.5 has been linked to cardiovascular issues, including heart attacks and strokes, as these tiny particles can enter the bloodstream and affect the heart.

Cancer Risk: Long-term exposure to PM2.5 has been associated with an increased risk of lung cancer, making it a serious concern for communities residing near mining operations.

Cardiovascular Effects: PM2.5 has been linked to cardiovascular issues, including heart attacks and strokes, as these tiny particles can enter the bloodstream and affect the heart.

Monitoring and Addressing PM2.5 Emissions

Open-pit mining operations must actively measure and understand particulate emissions to mitigate health risks. The CabSafe solution offers a practical and efficient way to achieve this goal. Here’s how:

Compact Size: CabSafe's compact size allows for easy deployment over large areas, ensuring comprehensive coverage of the mining site and surrounding regions.

Low Cost: Cost-effectiveness is a crucial factor in implementing monitoring solutions. CabSafe provides an affordable option for mining operations investing in air quality monitoring technology.

Low Power Consumption: CabSafe's low power consumption is a game-changer, enabling it to run on a small solar panel. This sustainability feature ensures continuous monitoring without relying on conventional power sources.

LTE-M Connectivity: CabSafe utilises LTE-M connectivity to offload real-time data online. This enables mining operators to access critical information promptly and take immediate action to address any spikes in PM2.5 emissions.

Pole-Mounted Setup: The CabSafe setup can be easily pole-mounted, allowing for flexible and strategic placement across the mining site. This adaptability ensures that monitoring is conducted where it matters most.

Their expertise in air quality monitoring solutions can help you proactively create a safer and healthier environment for workers and neighbouring communities. Together, we can work towards sustainable mining practices that prioritize the well-being of all stakeholders.

Managing Dust for Enhanced Electronics Reliability in Mining Operations

Dust and MTBF: Enhancing Electronics Reliability

In the realm of electronics, the presence of dust within electrical cabinets poses a multifaceted challenge. While dust may lead to shorts, depending on its composition, it also acts as an insulating layer, hindering proper cooling of electrical components. As we understand, the Mean Time Between Failure (MTBF) exhibits a strong correlation with the operating temperatures of electronics, characterized by an exponential relationship. Thus, ensuring dust-free environments that facilitate adequate cooling significantly bolsters the reliability of electronic components. This realization has prompted mining companies to adopt stringent cleaning procedures for critical electronics cabinets.

Cleaning Procedures and RCS: A Safety Concern

Pressurized air stands as the primary tool for periodically clearing dust from electrical cabinets. However, a substantial portion of this dust comprises Respirable Crystalline Silica (RCS), presenting a significant safety hazard for individuals conducting the cleaning. Exposure to RCS can contribute to severe ailments such as silicosis and lung cancer. Alarmingly, in 2017, the Queensland Mines Inspectorate reported that around 50% of all respirable dust and RCS exceedances observed in surface coal mines stemmed directly from compressed air usage during maintenance activities. Notably, a third of these exceedances specifically related to blowing out high voltage cabinets in electric drive trucks or motor-generator sets in dragline houses.

Prevention Over Remediation

Given the hazardous nature of cleaning operations, it becomes imperative to prevent dust intrusion into electrical cabinets altogether. This approach not only minimizes the need for risky cleaning procedures but also promotes a safer work environment. To support this preventive stance, CabSafe has collaborated with a mine operator in Australia to install CabSafe units inside the main electrical cabinets of Komatsu mining trucks. These installations serve as the baseline for quantifying the effectiveness of future improvements.

CabSafe Installation and Data Analytics

CabSafe operates as a fully self-contained air-analytics lab, requiring either 10-30VDC or a USB battery bank for operation. Data retrieval occurs via LTE-M or through a mobile phone, facilitating seamless offloading to the analytics portal. Its self-contained design allows for flexible deployment, enabling detailed air-quality assessments within driver cabins or electrical cabinets.

Measurement Insights

CabSafe’s built-in accelerometer enables the distinction between the truck’s stationary and driving states. Each graph provides averages and standard deviations for both datasets, highlighting notable differences in CO2 readings and particle concentrations between stationary and mobile states. Baseline readings underscore substantial room for improvement. Following enhancements to the air-cooling systems within these cabinets, we anticipate quantifiable improvements, which will be documented in future measurement campaigns.

Stay tuned for updates on our ongoing efforts to optimize the cooling of this Komatsu truck electrical cabinet!
