Research on conditional characteristics vision real-time detection system for conveyor belt longitudinal tear

Conveyor belt longitudinal tear is one of the most serious problems in coal mining. Existing systems cannot realise lossless and real-time detection for longitudinal tear of conveyor belt. Currently, visual detecting systems are proposed by many researchers and are becoming the future trend. A visual recognition system based on using laser...

Manometric determination of supercritical gas sorption in coal

The characteristics of the manometric method are investigated so that it can be used to obtain accurate data of sorption of supercritical gas in coal. Furthermore, data of the sorption of carbon dioxide, methane and nitrogen in coal at in situ conditions have been determined. Accurate data are required to develop a theory that can describe the...

Carbon dioxide transport and retention in coal

Dynamics of CO2 in coal as a reservoir

The mechanisms, by which the coal seams sorb, retain and store gases needs, to be understood. The results presented in this thesis give an insight into the dynamics of CO2 and other flue gas components in coal that are related to operation feasibility of ECBM projects. The main issues relate to the permeability behavior and the flue gas/ CO2...

Alkali metals in combustion of biomass with coal

Growing demand for energy in the world, depletion of fossil fuels and green house effect require from us to utilize alternative, renewable sources of power. Biomass gained in the last few years more and more attention especially in Europe. Many research programs focused on the various forms of thermal biomass utilization have been launched and...

Coal mining in the Netherlands: The need for a proper assessment

In the Netherlands several billion tonnes of mineable coal remained after closure of all mines in 1974. Mining activities in Dutch Limburg were suspended relatively early in comparison to surrounding basins, of which only DSK’s Ruhr mines are still producing. In retrospective this saved the costs of uneconomic exploitation and limited further...

Electromagnetic De-Shaling of Coal

The efficiency with which an electromagnetic sensor array is able to distinguish density and ash content of coal and shale mixtures was determined experimentally. The investigated sensor was originally designed for automatic metal detection and sorting in industrial glass recycle processing, where it is widely applied. In coal preparation, the...
