    Percussion-rotary method of drilling large-diameter dewatering wells in »Bełchatów« liginte mine
    (2016) Gasiński, Jerzy; Macuda, Jan; Kaczmarek, Tomasz
    Lignite opencast extraction can be performed after prior dewatering of the rock mass. Most frequently it is realized with large-diameter dewatering wells which have been mostly drilled with the invert mud rotary method and airlift. This method allows for quick drilling in lithologically diversifi ed aquifers, minimizing the negative impact of mud on the near-well zone. When drilling in dewatered carbonate rocks with the stone runs or well developed karst the effi ciency of this method considerably decreases. The technical and technological aspects of use of downhole hammers for drilling large-diameter dewatering wells in diffi cult geological conditions are discussed in the paper. Thanksto the use of this method for drilling wells in ‘Bełchatów’ Lignite Mine the drilling rate could be increased and the number of complications and drilling failures lowered.

    System obserwacji wód podziemnych w Kopalni Odkrywkowej Węgla Brunatnego Bełchatów - prace doskonalące jakość systemu
    (2008) Gasiński, Jerzy; Kaczmarek, Tomasz
    A system of observation holes is an indispensable element of a dewatering system, which acts both as a tool of control and reconnaissance. The efficiency and the usefulness of the observation system are a sum of individual efficiencies of its elements. Therefore the greatest stress is laid on the assurance of the best possible technical state of the piezometer. Through the adequate selection of drilling diameter, the granulation of the cover, type of the filter and the process of activating, we want to achieve the best efficiency of the plumbing-active part of the filter. The continually evolving system of the technical state control will allow us, in the near future, to thoroughly assess the usefulness of the separate monitoring holes for the entire system. This, ultimately, will lead to a raise of information value.
