  2. 1. Short-term Underground Mine Scheduling : An Industrial Application of Constraint Programming

    Author : Max Åstrand; Mikael Johansson; Mats Carlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduling; mining; underground mines; constraint programming; large neighborhood search; korttidsplanering; gruvdrift; underjordsgruvor; villkorsprogrammering; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The mining industry is facing a surge in automation in the pursuit of safe and profitable operations. As the excavation process is increasingly automated, today's mining companies seek to optimize the coordination of the now automated mining activities. READ MORE

  4. 2. Short-term Underground Mine Scheduling : Constraint Programming in an Industrial Application

    Author : Max Åstrand; Mikael Johansson; Christian Schulte; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduling; mining; mine; underground; constraint programming; cp; large neighborhood search; lns; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The operational performance of an underground mine depends critically on how the production is scheduled. Increasingly advanced methods are used to create optimized long-term plans, and simultaneously the actual excavation is getting more and more automated. READ MORE

  5. 3. Short term water heat storage : studies of velocity and temperature fields and their importance for sizing of the storage

    Author : Jan Dahl; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Short term water heat storage's have been introduced in many district heating systems. The main reason for this is the possibilities opened by the storage for optimization of the generation of heat and electricity in combined heat and power plants. READ MORE

  6. 4. Short term water heat storage : an experimental and numerical investigation of phenomena that affect the degree of thermal stratification

    Author : Roger Hermansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Thermal stratification was studied by measurements of the temperature and velocity fields in water heat storage's and by numerical simulations. The work includes experimental investigations in three model heat storage's of different size and comparisons to numerical simulations for two of the storages. READ MORE
