Automation is transforming the mining industry, offering increased efficiency, safety, and productivity. Let’s explore several significant pitfalls and challenges accompany its adoption: High initial investment The cost of purchasing, installing, and integrating automated machinery and digital infrastructure is substantial. While long-term savings are possible, these upfront expenses can be a financial burden, especially for smaller […]

Wedges are used in conventional or wireline drilling. A wedge is set in a borehole so that it deflects the drill string in the desired direction when drilling recommences. Roller jet bits are used in oil drilling. A roller bit with a large jet on one side is often used to change direction. The drill […]

Drilling has existed as an industry since the Chinese erected the first cable-tool rig approximately 4000 years ago. Since the development of drill rigs, techniques and applications have led to the industry’s expansion multiple specialised sectors. Definitions of each drilling sector follow, along with brief outlines of the applications involved. Processes and spheres of influence […]

Sublevel caving (SLC) is most effective under specific geological conditions characterized by: Orebody geometry and dip: SLC is particularly suited for steeply dipping ore bodies, generally greater than 60°, and can also be applied to very thick and massive deposits. The orebody is typically divided into vertical slices for systematic extraction from top to bottom. […]

Controlling internal and external dilution in mining operations is essential to maximize ore recovery and minimize unnecessary waste material, which can significantly impact the overall profitability of the mine. Dilution control is crucial for maintaining the economic viability and sustainability of mining projects. By incorporating these strategies into their mining practices, companies can optimize their […]

A driller understands the various processes involved in creating a borehole; such as crushing, abrasion, impact, tearing, twisting, cutting, erosion, stirring or sluicing, and excavation. This knowledge enables the driller to adapt drilling methods to suit specific applications. An experienced driller relies on multiple senses to monitor downhole conditions. They observe instrument readings, like pressure […]

Drillers are as diverse a group of people as the industry in which they work. Every drilling operation is different and requires a highly skilled person to ensure that the drilling process is successful. Drillers should have a mechanical background and enjoy working with machinery. They are resourceful people, capable of solving problems as they […]

This article focuses on innovative methods adopted by an aggregate company to enhance the efficiency of its drilling and blasting operations. The primary objective is to streamline the process, reduce costs associated with both primary and secondary blasting, and ultimately extend the operational life of loading, hauling, and crushing equipment. Rock drilling marks the initial […]

Premiums for consumers buying aluminium on the physical market in the United States hit a record 60 cents a lb or $1,323 a metric ton on Thursday after U.S. President Donald Trump imposed higher tariffs on U.S. imports of the metal. The tariffs doubled to 50% on Wednesday. The U.S. Midwest duty-paid premium has gained […]

Canadian companies and a major union said on Wednesday higher U.S. tariffs on steel and aluminum could result in more job losses and lost sales, as Prime Minister Mark Carney said Canada is preparing reprisals. The U.S. tariff hike on the two metals to 50% from the 25% rate introduced in March took effect at […]

The Puutu Kunti Kurrama and Pinikura (PKKP) Aboriginal Corporation and Rio Tinto have signed a Co-Management Agreement to support a lasting and trusted partnership. The agreement is the overarching framework for Rio Tinto’s iron ore operations on PKKP Country and formalises how they engage on proposals affecting heritage and social surroundings throughout the mine lifecycle. […]

Introduction Mining has long faced safety hazards, labor intensity, and environmental harm. Traditional mining demands heavy manual effort, which increases risks and costs. Robotics and automation now offer safer, faster, and more eco-friendly mining through AI-driven equipment control and data monitoring. Enhancing safety through robotics Reducing human exposure to hazards Mining involves dangers like unstable […]

The introduction of driverless (autonomous) trucks in surface mining has brought significant changes to the industry, affecting safety, productivity, workforce roles, and risk profiles. in the line below, we highlight some impact of driverless trucks in surface mine. Safety improvements and new risks Reduced human exposure: the primary benefit of autonomous trucks is improved safety, as […]

To reduce the occurrence of boulders during blasting, it’s essential to combine smart blast design, accurate drilling, and real-time monitoring. In this article we provide a structured approach based on proven techniques and current industry practices: Optimizing blast design Effective blast design plays a critical role in achieving good fragmentation. One proven strategy is using […]

The expertise of truck drivers plays a vital role in mining productivity, significantly impacting safety, operational efficiency, fuel usage, and overall costs. Experienced drivers maintain higher levels of alertness throughout long and often monotonous shifts, helping to prevent fatigue-related incidents. Since fatigue and drowsiness are leading causes of accidents in haul truck operations, addressing driver […]
