LKAB’s Kiruna Mine, located in northern Sweden, produces about 24 million tons of iron ore yearly using an underground mining method known as sublevel caving. To efficiently run the mills that process the iron ore, the mine must deliver planned quantities of three ore types. We used mixed-integer programming to schedule Kiruna’s operations, specifically, which production blocks to mine and when...

The principal objective of this work is to contribute to the development of effective remote autonomous mine countermeasure operations by providing pertinent flow, heat flux and sediment transport characteristics in the benthic boundary layer to missions engaged in sea mine reconnaissance and hunting. These environmental characteristics govern acoustic and light propagation, chemical and biogen...

Mine disasters claim thousands of human lives and cause millions of property loss every year. The safety of the mine worker is of paramount importance in any underground environment. Advances in the development of Wireless Sensor Networks (WSNs) for monitoring infrastructure health, and environmental conditions provide end users with the benefit of low-cost installation, maintenance and scalabi...

The increases above 1975 levels for acid mine drainage and subsidence for the years 1985 and 2000 based on projections of current mining trends and the National Energy Plan are presented. No increases are projected for acid mine drainage from surface mines or waste since enforcement under present laws should control this problem. The increase in acid mine drainage from underground mines is proj...

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...

Monitoring data in coal mine is essentially data stream, and missing coal mine monitoring data is caused by harsh coal mine environment, therefore coal mine safety evaluation can be seen as incomplete labeled data stream classification. The method is proposed for unlabeled data and concept drift in incomplete labeled data stream in this paper that uses semi-supervised learning method based on k...

In Escherichia coli MinE induces MinC/MinD to oscillate between the ends of the cell, contributing to the precise placement of the Z ring at midcell. To do this, MinE undergoes a remarkable conformational change from a latent 6β-stranded form that diffuses in the cytoplasm to an active 4β-stranded form bound to the membrane and MinD. How this conformational switch occurs is not known. Here, usi...

Mine safety assessment is a precondition for ensuring orderly and safety in production. The main purpose of this study was to prevent mine accidents more effectively by proposing a composite risk analysis model. First, the weights of the assessment indicators were determined by the revised integrated weight method, in which the objective weights were determined by a variation coefficient method...

In order to ensure that the Sudbury Neutrino Observatory (SNO) is clean, some simple methods need to be developed for the cleanliness monitoring program. Two methods arc selected and examined. The two methods. X-ray fluorescence and optical counting, can be used for detecting and quantifying the amount of mine dust on flat surfaces. X-ray fluorescence is based on element detection, a method tha...
