Mine operators face increasing uncertainty. For example, mineral price volatility, weather conditions, operating performance, supply chain disruptions, etc. impact their ability to sustain cost-effective production. Drilling is a primary activity that affects operating performance. Failures of drilling equipment seriously impact production. Unplann...

Since 2012, low commodity prices have forced many mining companies to suspend or cease operations. To remain in business, some mine managers are exploring strategies to reduce operational costs. Given its importance as a cost element, increasing bench drilling efficiency and performance in open-pit mines has the potential to generate considerable s...

Madencilik endüstrisi belirsizliklerle dolu operasyonlar bütünüdür. Bu belirsizliklerin göz ardı edilmesi yapılan hesaplamalarda hatalar meydan getirmekte ve tahmine dayalı kararların yanlış verilmesine neden olmaktadır. Doğru tahminlerin yapılması için bu belirsizlikleri hesaba katacak benzetim teknikleri kullanılması gerekir. Benzetim teknikleri,...

Madencilik, oldukça zor koşullarda gerçekleştirilen ve farklı iş kollarının bir bütün halinde uygulandığı multidisipliner bir sektördür. ILO (Uluslararası Çalışma Örgütü) istatistiklerine göre maden iş kollarında çalışanlar, farklı iş kollarında çalışanlara göre en az 3 kat daha fazla kaza maruziyet riski taşımaktadır. İş güvenliği, kavramsal olara...

In the mining industry, significant progress and increased mineral production cause waste disposal issues which is one of the crucial problems in mining operations. It leads to both environmental and economic issues. Particularly, wastes from the production of metallic sulfide ore cause serious environmental pollution. In the last three decades, wa...

Doğru tahmine dayalı zamanında kararlar, maden endüstrisi için daha iyi sonuçlar vermektedir. Benzetim teknikleri, sistemleri doğru bir şekilde modellemek ve oluşabilecek farklı senaryoların sonuçlarını tahmin etmek için yıllar içinde geliştirilmiştir. Bu tür benzetimlerin doğru şekilde modellenmesi, büyük sermaye yatırımları içeren, güvenilir ve k...

Low commodity prices have forced many mining companies to explore new strategies to minimize operating costs. One cost-saving strategy is to increase drilling efficiency and performance, specifically in open pit mines; drilling operations are expensive, and they directly and indirectly affect most aspects of the mining process. A substantial portio...

In recent years, commodity prices have swiftly decreased, narrowing the profit margin for many mining operations and forcing them to find effective cost management strategies to respond to low prices. Given that equipment is one of the most significant assets of a mining company, efficient equipment utilization has strong potential to reduce costs....

One of the most important responsibilities that employers have to fulfill against the employee is ensuring the safety of employees in the working environment. The personal protective equipment (PPE) is the last resort in case the danger cannot be eliminated despite the required measures taken in the working environment. The user-oriented design of...

Mineral commodity prices have declined in recent years. This decline forces mining companies to find effective cost-management strategies to sustain their operations. Otherwise, many operations will be ceased or suspended. Effective equipment utilization has a strong potential to reduce operational costs. Furthermore, unexpected events or failures...

Proper risk management is mandatory to eliminate risk factors for the health of the employees and the safety of the system by providing a safe working environment and keeping the risk, which cannot be eliminated, at the lowest possible level. After the risk assessment, the prevention methods can be sorted in order of importance; eliminating the ris...

To gain a competitive edge within the international and competitive setting of coal markets, coal producers must find new ways of reducing costs. Increasing bench drilling efficiency and performance in open-cast coal mines has the potential to generate savings. Specifically, monitoring, analyzing, and optimizing the drilling operation can reduce dr...

In recent years, the profit margin for mining companies has been declining due to low commodity prices and high operating costs associated with resource degradation and system aging, forcing mining companies to reduce operating costs in order to maintain operations. Cost savings presented by new technologies and computational resources that allow c...

Problem statement: Increasing efficiency and performance of bench drilling in open-pit mines has the potential to generate considerable savings. This increase can be realized by monitoring the drilling operation, analyzing monitoring data with statistical tools and optimizing operational variables. Finding the best configuration of controllable dri...

Mineral commodity prices have declined in recent years. This decline forces mining companies to find effective cost management strategies to sustain their operations. Otherwise, many operations will be ceased or suspended. Effective equipment utilization has strong potential to reduce operational costs. Furthermore, unexpected events or failures du...

Cost is the main concern for the mining industry. System aging and resource degradation are the main reasons for increasing operating costs in mining activities. Thus, it is necessary for mine management to pay attention in order to reduce operating costs through operation rationalization and continuous improvement. In this frame, reducing drilling...

The high cost of drilling has a serious impact on mining operations requiring strategies which use advanced technologies and techniques that closely monitor the drilling operations to reduce costs and maximize performance. Experimental design and analysis methods are used to investigate controllable parameters of drilling activity evaluation of the...

Drilling is one of the primary operations in open-pit mining cycle. Any failure in drilling equipment affects operational production schedule directly. Therefore, analysis of drilling system reliability and availability are to sustain the operation. In this paper, whether the drilling machine exhibits a trend; if so, type of trend, a fitting a mode...

Design of the fill or backfill material has been an important subject for rock engineers due to the increased volume of underground mining operations as well as the environmental concerns raised from mineral processing plant tailings. Filling operations are useful for underground mining not only for the use of the opening as a tailing deposit but a...

Günümüz madenciliğinin en büyük problemlerinden biri olan atık bertarafı ekonomik ve çevresel faktörler dikkate alındığında önem arz etmektedir. Özellikle metalik sülfiirlü cevherlerin üretimi sonucu sülfür içeriği yüksek atık, su ve oksijen varlığında sülfiirlü minerallerin oksidasyona uğraması, asidik su oluşumuna ve atık içindeki metallerin çözü...
