Prediction of the Potential Daily Output of a Shearer-Loader

Economic analysis allows for determining the required daily output under certain natural and mining conditions based on costs of production process in a particular mine infrastructure. Therefore, there is need to determine potential longwall using technical equipment at disposal mine. In case mines, when exploiting few longwalls simultaneously bumping hazards, it indispensable ensure safety. Due necessity keeping safe distance among fronts, planning their exploitation, developing prediction advance during period needed. To predict from analyzed period, necessary know current operating time machines capacity shearer given conditions. The working results available degree its utilization, which determined by sum unplanned breaks process. productivity haulage speed. Both factors mentioned above are random. Hence, calculation module has been developed, whose task estimate distribution parameters these indicators empirical data. algorithm estimating one distributions: normal, steady or gamma special exponential Poisson obtained input data, constituting sample population, proposed. data sequence numbers measurement machines. These can be memory card, recorded each longwall. On this basis, possible generate random values both individual days operation. possibility speed, shearer’s characteristics computer simulation process, also discussed. carried out GeneSiSv.3.1 software, developed designing picks layout drum. take into account loading cutting It presented that, coal with compressive strength 27 MPa, speed limited drum and, greater cuttability, power electric motor driving paper presents algorithms describing procedure generating assumed period. subject matter part bigger project concerns operation hazards.
