· Concept drift detection is a crucial task in data stream evolving environments. Most of the state of the art approaches designed to tackle this problem monitor the loss of predictive models. Accordingly, an alarm is launched when the loss increases significantly, which triggers some adaptation mechanism ( retrain the model).
Therefore, he created Summit Mining: the way to make cryptocurrencies accessible to all, in an ethical and profitable way. ... At a time when there is a lot of talk about cloud mining, Summit Mining preferred to focus on community mining. A major difference, since each member physically owns a share of the mining equipment. Like a real estate investment trust, where you buy shares in real ...
Block caving is an inexpensive bulk mining method where the ore is drawn by gravity and which is suitable for ore bodies which are low grade and are consistent in their grades. Depending on how the ore is broken there are three block caving systems 1) The Grizzly system for fine material, 2) the slusher system for coarser material and 3) the LHD system for very coarse material. Full gravity ...

· Abstract. Mine haulage drifts are the arteries of any mine, as they are used to transport the valuable ore out of the mining zones as well as to move operators and equipment. Hence, their stability is crucial in underground mines. Drift instability could lead to serious consequences such as injuries, production delays and higher operational cost.

Concept drift in process mining (PM) is a challenge as classical methods assume processes are in a steadystate,, events share the same process version. We conducted a systematic literature review on the intersection of these areas, and thus, we review concept drift in PM and bring forward a taxonomy of existing techniques for drift detection and online PM for evolving environments ...

At times of high metal prices, mining projects that have previously been put into the too hard basket' are now being more closely examined. Typically these projects include the potential recovery of small mineable tonnes with high contained metal values and often with poor ground conditions. For many underground mining projects, the drift and fill method is viewed as a highcost method and a ...
In mining: Horizontal openings: drifts. All horizontal or subhorizontal development openings made in a mine have the generic name of drift. These are simply tunnels made in the rock, with a size and shape depending on their use—for example, haulage, ventilation, or exploration.
Access drifts. A drift (or access) is an excavated tunnel built for the purpose of providing a pathway for the transit of equipment, services or ore between different loions in an underground mine. Installing Rock Bolts and Screen at Rio Tinto Diavik, 2014, Lac de Gras, NT, Canada.

![[] A Framework for Explainable Concept Drift ...](/f8bu3kq/617.jpg)
· Research in process mining has so far only focused on detecting, loing and characterizing significant changes in a process and not on finding root causes of such changes. In this paper, we aim to close this gap. We propose a framework that adds an explainability level onto concept drift detection in process mining and provides insights into the causeeffect relationships behind .
