The Summitville Mine was a high-elevation (3500 m) gold mine in southwestern Colorado. The mine was abandoned in 1992, leaving approximately 200 ha of disturbance comprised partially of an open pit, a cyanide heap leach pad, and two large waste rock piles. Reclamation of these mine facilities is challenging due to extreme climatic conditions in conjunction with high acid-production potential an...

One of the most critical aspects open pit mining is dewatering and mine drainage systems. The NCP Open Pit Gold Mine located in Central Kalimantan. This study area has a range rainfall intensities durations from moderate to heavy. Good required manage runoff water reduce entering front loading. used daily intensity data 1994 2018. Using Mononobe Method, hydrological for this were evaluated by d...

There are some large scale orebodies that extend from surface to the extreme depths of the ground. Such orebodies should be extracted by a combination of surface and underground mining methods. Economically, it is highly important to know the limit of upper and lower mining activities. This concern leads the mine designers to the transition problem, which is one of the most complicated problems...

This paper focusses on the description of reliable, safe and economical treatment of mine water from different types of mines and applications by advanced membrane systems. The applications include mine drainage water from underground mines, intrusion water in open pit mines and excess water from tailing storage facilities. The illustrated references confirm the existence of robust, reliable, a...

A dynamic optimization method was created to address the production schedule issue in an open-pit coal mine while taking into account characteristics of fuzzy structured element. The mining capacities all “geologically optimal push-back bodies” were then examined using moving cove method. One most crucial elements process scheduling is pricing. As a result, this work also presents technique for...

This paper presents an approach towards computationally efficient discrete-event-simulation designed to take advantage of high-performance computing architecture. We demonstrate how computational efficiency combined with large capacity enables quantification and mapping stochastic system performance across a challenging multidimensional parameter space requiring several million individual DES i...

Adequate water distribution in mines is crucial for both cooling and production. As deep-level become deeper, the requirements, subsequent dewatering also increase. Numerous studies on mine planning exist; however, these fail to recognise integrated nature of system, which comprises service supply system. These commonly neglect intensity, life-of-mine planning, use zero-waste baselines. In this...

Truck-Shovel (TS) systems are the most common mining system currently used in large surface mines. They offer high productivity combined with flexibility to be rapidly relocated and adjust load/haul capacity capital expenditure according market conditions. As world moves decarbonise as part of transition net zero emission targets, it is relevant examine options for decarbonising haulage In-Pit ...
