Iniekcyjne uszczelnianie i wzmacnianie górotworu przed czołem przekopu łączącego 1 drążonego przez strefę uskoku andaluzyjskiego w warunkach Zakładu Górniczego »Piekary«
(Wydawnictwa AGH, 2005) Rembielak, Tadeusz; Łaskawiec, Leszek; Majcher, Marek; Mielcarek, Zygmunt
In ZG »Piekary« there was a necessity to undertake a binding cross-cut 1 in the seam 506 through the Andaluzia Fall Zone in the range of the mining area »Brzeziny IV« and »Rozbark II«. In order to avoid several problems and to increase safety during undergoing the cross-cut through tectonically distributed zone, there was designed advancing by cementation, sealing and firming of a rock mass in front of its head, using injectory holes drilled by drills.

Iniekcyjne wzmacnianie górotworu podczas przebudów rozwidleń wyrobisk korytarzowych
(2007) Rembielak, Tadeusz; Krella, Jan; Rosikowski, Janusz; Wala, Franciszek
The occurring mineral water in KWK »Piast« cause corrosion of the excavations' lining. Because of that it is necessary to rebuild these dog headings. In order to increase safety during rebuilding dog headings junctions, there were applied forthcoming injectory firming the rock mass in its surrounding, which prevents from occurring the fall of rocks and from the results of these fallings. In the paper there was presented an exemplary technology of headings junctions rebuilding in KWK »Piast«.

Iniekcyjne wzmacnianie górotworu podczas przebudów wyrobisk korytarzowych jako sposób zapobiegania obwałom skał i skutkom tych obwałów
(Wydawnictwa AGH, 2005) Rembielak, Tadeusz; Mielniczuk, Lech; Rosikowski, Janusz; Rusinek, Józef; Wala, Franciszek
The occurring mineral water in KWK »Piast« cause a corrosion of the excavations lining. Because of that it is necessary to rebuild these dog headings. In order to increase safety during rebuilding crossing of excavations there were applied forthcoming injectory firming of the rock mass in its surrounding, which prevents from occurring the fall of rocks and from the results of these fallings. In the paper there was presented an example of crossing rebuilding technology from a lining LP to the crossing of the POLYTRAB type in the Heintzmann Company in KWK »Piast«.

Iniekcyjne wzmacnianie górotworu poprzedzające przebudowę rozwidlenia wyrobiska korytarzowego jako sposób zapobiegania obwałom skał i skutkom tych obwałów
(Wydawnictwa AGH, 2009) Rembielak, Tadeusz; Kudela, Jacek; Rosikowski, Janusz; Wala, Franciszek
The occurring mineral water in KWK »Piast« cause corrosion of the excavations' lining. In order to increase safety during rebuilding of dog headings' forks forthcoming injectory firming of the rock mass in its surrounding were applied, which prevents from occurring the fall of rocks and from the results of these fallings. An exemplary technology of fork rebuilding in KWK »Piast« at the level of 500 m was presented in the paper.

Zwiększenie bezpieczeństwa podczas rozruchu ściany 375 w KWK »Piast« na drodze iniekcyjnego wzmacniania pokładu 209 przed jej czołem
(Wydawnictwa AGH, 2009) Rembielak, Tadeusz; Kudela, Jacek; Krella, Jan; Rosikowski, Janusz; Zamarlik, Bogdan
In order to safely reinforce and perform the movement of the wall 375-1353 in the seam 209 in KWK »Piast«, injectory firming of the seam before its face was designed. Applying the injectory firming of the wall's face eliminated movement of loose rocks from the cutting, and the roof to the wall's cross-cut during reinforcing and starting of the wall, and as a result of that the aim of work was achieved.
