Construction of the new mining level 950 m in »Borynia« Coal Mine caused that a new complex of headings of the main supply and drainage system must have been built. Pump Chamber is one of the headings of this complex. Taking into account both the heading section in the breakout which equals about 50 $m^{2}$ and the peculiar construction of the V36 support, the construction works of this chamber required preparation of atypical technology to drive this heading. In the article, the process of construction of the whole heading complex has been presented starting from the final stage of the bidding up to hanging over the finished construction to the Investor. Enterprise of Mining Works in Rybnik, which acts within Consortium of Polish enterprises for underground works and shaft sinking Join-stock company, was charged with this construction. All the stages of driving the pump chamber, made in a special lining - 6.5 m in width and 7.0 m in height, have been precisely described as the technology is unusual.
