Opis:
The handling operations are the inseparable element of production processes. The percentage of this type of work, in reference to other production activities, can reach even high levels bringing the increase of expended costs. The capital consumption of handling works affects the improvement of a proper selection of means to assure the production profitability. An important issue of selecting the handling means is based on their work efficiency evaluation. The paper contains the description of the software (developed at The University of Life Sciences in Lublin), that would be helpful in solving the real problems associated with the selection of the continuous handling means used for works planned to do during a production process. The described software is an application consisting of forms that reflect divisions of means for continuous handling and connected databases for storing auxiliary information and results of calculations performed. The principle of the software is based on making calculations of the work efficiency as well as exploitation costs for continuous handling means. Additional values are: ease of data input and search for means characterized by possibly the lowest exploitation costs. Correctness of the software functioning was verified on an example related to comparison of three conveyor types.

Opis:
The first part of the paper concerns the natural deposition conditions of the 325/1 seam in the “W” coal mine, in the 102 longwall mining panel. It also presents the most important technical conditions regarding the exploitation at this longwall. To characterize the methane hazard in the longwall area, the parameters of ventilation and total methane concentrations as well as the volumetric flowrate of methane captured by the methane removal system, have been presented graphically. A significant part of the methane flow in the longwall area was released to the air flowing to the longwall. The most significant part of the article is the presentation and analysis of the results of prognoses of mean methane concentrations at the exhaust of the longwall area. The accuracy of the prognoses of methane concentration was verified using two methods: while not considering the release of methane to the air flowing to the longwall and while considering the total flowrate of methane to the ventilation air in the area of the 102 longwall. The method of forecast presented in the article has so far been checked for a 5-day and 6-day work day, as well as for walls operating in a non-regular mode. The article refers to the wall operating in a continuous mode, which required adaptation of the proposed method to this mode. The application of the one-day forecast proposed in the article allows for undertaking temporary methane prevention measures enabling safe use of the wall.
