Ocena rozwiązań projektowych likwidacji szybów zastosowanych w procesie restrukturyzacji polskiego górnictwa węglowego
(Wydawnictwa AGH, 2009) Czaja, Piotr
The significant changes in the mining potentials of the Polish mining industry can be characterized by a substantial number of mines that were closed down and particularly by a big number of shafts that were liquidated. In the past 30 years 35 hard coal mines have been closed down, which resulted in the necessity to liquidate 392 shafts, including 41 shafts in metal ore mines and 7 in salt mines. The remaining ones were located in hard coal mines. Thus, in the past 50 years the Polish mining industry has been first the place of a massive construction of shafts and then of a similarly massive liquidation. Such experience should not be forgotten and must be passed on to the future generations of engineers responsible for the Polish mining industry. The paper constitutes a preliminary evaluation of the design solutions that were applied in this period of substantial transformation.

Uwagi o projektowaniu technologii zamrażania górotworu dla potrzeb głębienia szybów
(2007) Wichur, Andrzej
Domestic experiences indicate that the method of rock mass freezing may be applied practically in all geological-mining conditions; the sole limitation here are the costs, which, in many cases, render deepening with this method uneconomic. The collected research results and the need for applying this technology substantiate the requirement of evolving refined principles of designing technologies of freezing the rock mass to deepen shafts in the conditions of water-logged overlay of considerable thickness. These principles ought to be based upon previously elaborated guidelines that had proved their suitability during the designing of the rock mass freezing in the conditions of the Lublin Coal Basin.
