Definitions

  • the invention relates to a method for controlling the discharge of dissolved in underground mining at different points of the mine mining systems Haufwerks about arranged in the mine building funds and bunkers to equipped with a conveyor shaft or to a raw coal transfer point on the day, for example, a raw coal storage.
  • a bunker conveyor overlapping with a second extension conveyor which, in order to increase its storage capacity, has a correspondingly greater length and possibly additionally a correspondingly larger transport cross section than the second extension conveyor, wherein the control or adaptation of the storage capacity by means of a corresponding control of the Conveying speed can be made.
  • the invention is therefore based on the object of specifying a method of the aforementioned type, by means of which a maximum and as constant as possible product delivery to the shaft promotion of a mine can be realized.
  • the invention provides a method in which for the individual conveyors and bunkers connected downstream of each individual picking machine the lowest available conveying capacity of the conveying means and buffering capacity of the bunker systems is determined on the basis of continuously recorded actual data and in a computer-aided control unit with the current one Is-recovery performance and / or expected for a given period target recovery capacity and / or on the past actual data projected plan performance of the associated pinwheeling machine is compared and where detected discrepancies, the control unit automatically compensates for capacity between the individual different siphoning machines downstream funding and Bunkeranlagen by appropriate control of the individual subsidies and bunker systems, taking into account their maximum Fö Coder performance or buffer capacity causes and / or controls the extraction capacity of the in-picking machine, taking into account the respective available delivery capacity of the downstream funding and buffer capacity of bunkers controls.
  • the control method does not provide for any change or adaptation as long as the capacity of the downstream conveyors and bunker systems is equal to the current or for a fixed forecast period planned recovery of a single sear picking machine, taking into account other quantities of HUF received by other siphoning enterprises.
  • the control system automatically compensates for capacity between the different conveying means or bunker systems connected downstream of the different siphoning units, taking into account the actual value given to this squeezing machine. state or the planned in the considered prognosis period target state made, so that, taking into account all individual flow rates an optimum flow rate is achieved.
  • the invention it is possible in an advantageous manner to identify upcoming bottlenecks in the transport routes by predictive forecasting of the processes, both on the extraction side and on the production side, and to counteract them at an early stage and thus by means of suitable measures tailored to the overall system of a mine to avoid in the extraction and advance payment. Since in practice not all mine mining operations oriented in a mine building can and do run at the same time, the production readiness of the mining companies is to be determined for a certain predefined forecast period and then all capacities of the production facilities, including the required buffer capacities, are controlled in such a way that an optimal production volume is carried away becomes.
  • the individual conveying means can be controlled from the shaft back to the extraction means so that they are always operated at a performance limit to be determined and thus "quasi" generate a suction towards the shaft. In this case, if sufficient conveyed is provided, the leading funding will be increased in its actual promotion until the trailing funding has reached its capacity limit. Insofar recognizes and avoids the control system, the critical bottleneck in the discharge, the so-called bottle-neck.
  • the inventive method makes it possible to take planning influence on the quality of the coal subsidized by depending on the raw material properties such as sulfur, chlorine and / or ash content of coal in the different extraction operations coal extraction performance the individual sheres are modified and adapted, whereby at the same time and automatically by adjusting the capacities of the Downstream funding and bunkering is ensured that the specified quantities and qualities within the specified period at the shaft for promotion are available.
  • the speeds of the conveying means and the bunker withdrawal rates for the current buffer capacity of the bunker systems are recorded as actual data for the current conveying capacity of the conveying means.
  • the maximum delivery rate of the conveying means is determined on the basis of performance data of drive motors and / or limit values for engine flows and / or limit values for engine temperatures.
  • a variable adjustment of its speed is given to adapt the vorzuhaltenden buffer capacity of a conveyor.
  • the target recovery time related to the predetermined period of time and / or the past actual data is determined on the basis of the seam thickness and the feed rate of the in-picking machines, wherein, according to a further alternative embodiment, the personnel occupancy of the respective Recovery operation and / or the maintenance data such as maintenance intervals and inspection data.
  • the methane content and / or the CO content is included in the determination of the desired recovery capacity.
  • the recorded actual data from the process of harvesting and conveying in the control unit in some sense logically with each other linked or set in relation to each other, the control unit in response to it by means of suitable computer programs the downstream resources and / or the extraction machines correspondingly controls or identifies their free capacity.
  • control unit causes an increase in the extraction power due to the respective free, not yet exhausted delivery capacity of the downstream funding.
  • control unit Furthermore, it can be provided that the actual data, the desired data and the control processes effected by the control unit are visualized.
  • the scheduling preview is called for a one-touch operation with a temporary priority change.
  • An extraction operation "A" is occupied with two layers; the target subsidy is 4,200 t / d.
  • the control unit checks in an automatic opportunity and risk assessment whether the extraction operation "A” can be temporarily provided with a higher discharge capacity without additionally operating production facilities " B “and / or” C "miss the daily target in the event of a possibly temporary reduction in the removal capacity to be allocated to them, so that the overall result is the best possible flow rate for the extraction operations "A", "B” and "C” is achievable.
