  • Patent number: 8380345
    Abstract: A method for controlling the extraction capacity of longwall operations in underground coal mining, including ascertaining the respective demand of the longwall operations, for air-technology and climate-technology resources, as influencing variables for a projected delivery quantity on the basis of data applicable to equipment of the longwall operations and to mineral deposit parameters, and storing the ascertained influencing variables in a computer as target data. Actual data for a raw coal delivery quantity, for air flowing through, for the supplied cooling capacity, and for the exhaust gas during running operation is detected and conveyed to the computer. If an increased demand for resources is recognized, coverage is initiated via a changeover of excess resources available at other longwall operations or, if a reduced demand for resources is recognized, excess resources are rerouted to other longwall operations experiencing corresponding demand deficiencies.
