Removal of mine shafts is a complex issue especially in terms of existing threats of water and gas. Method of winding shaft and the choice of material depends on the hopper of the excavation, its equipment, the existing horizontal connections to the pits and the extent of inflow. In the event of liquidation of the shaft, partially filled with water has a fundamental importance of proper selection of the type of material hopper. Skip and fine material, or combination of these materials should demonstrate the ability to solidify the aqueous medium, and after solidification have a soak resistance to or re-liquefaction. Skip and solidified material should also exhibit sufficient stability of the burden resulting from successive portions of the material entering the hopper shaft. This paper will be presented the results of laboratory tests on the potential use of fly ash from fluidized bed boilers to eliminate the shaft. The choice of fill material is related to the stability of the column filling feeder point of intersection of the shaft of the excavations on different levels. There is also a dependence on the choice of fill material requirements for gas permeability. There is no material that would be absolutely impervious to gases. With the increased demands that the permeability to gases, choose a filler with an effective hydraulic binder. The paper presents the results of selected physical and mechanical properties ofmixtures of fly ash-based water drawn from the ashes taken from the fluidized bed boilers burning coal plants: Plant “J”, Power Plants, “C” Power Station “T” and burning brown coal: the Power “TU”.
