Artykuł przedstawia problematykę bezpiecznych metod czyszczenia i kontroli zbiorników węgla, eksploatowanych w warunkach dołowych kopalń węgla kamiennego, na przykładzie JSW S.A. KWK „Pniówek". Zwraca uwagę na aspekt zagrożenia związanego ze specyfiką prac na wysokości oraz potrzebę minimalizowania tego zagrożenia poprzez wykorzystanie do tych czynności technik alpinizmu przemysłowego.

Coal reservoirs are an important element of the technological process. Their walls may be contaminated with sediments from the mined coal (overhangs on the housing of tanks and even jamming at their outlets) hindering their operation, which results in disturbances of the mine's operations. The applicable regulations impose an obligation on the entrepreneur to carry out a periodic inspection of the condition of coal reservoir housings. Each inspection is preceded by thorough cleaning of their housing, ensuring safety of the inspectors and reducing the problems related to the operation of the tanks. In the mining industry, inspection of brickwork of reservoirs is carried out in one of three ways: from the pile of mined coal accumulated in the tank, from a mobile platform suspended on ropes attached to beams that are built into the ceiling of the chamber above the reservoir, or using industrial mountaineering techniques. The article describes the use of mountaineering method on the example of Hard Coal Mine „Pniowek". Cleaning and inspection of reservoirs is carried out here by specialised rescue teams for operations in vertical workings, on action basis. Their plan is reviewed each time by the district mine rescue station. The actions are carried out by specialised rescue teams. Owing to this, their members can improve their skills, work out and consolidate the procedures. All this together allows for carrying out the work safely with the use of mountaineering techniques, and ensures uninterrupted operation of coal reservoirs.

W artykule opisano przykładowe akcje ratownicze i prace szczególnie odpowiedzialne, wykonane przez zespół specjalistów ratowniczych z „Wysokościowego zastępu ratowniczego do prac w wyrobiskach pionowych i o dużym nachyleniu KWK »Pniówek« z wykorzystaniem technik alpinistycznych”. Przedstawiono również nowoczesny sprzęt alpinistyczny stosowany przez ratowników – alpinistów.

n 1998, a "High-altitude rescue team for works in vertical and steep slope excavations of the Pniówek coal mine with the use of climbing equipment" , consisting of 22 rescuers, was established as of 1/08/2019. The basic climbing equipment used by the team is manufactured by Petzl: Avao Bod Croll Fast harness, ASAP fall--arrester, self-braking descenders with auto-lock function I'D or RIG and Ascension handled rope clamp for rope ascents. The members of the team, in addition to works related to the inspection and repair of coal tanks and shafts without hoisting equipment, take part in rescue operations and various types of particularly responsible tasks. The first rescue operation was carried out by the members of the team already in 1999, during the liquidation of shaft III in the Morcinek coal mine. In 2005, an injured employee who fell into a retention tank at the level of 830 m in the Pniówek coal mine was evacuated. Subsequently, the rescue team performed works related to: reconstruction of the ventilation duct in the area of the ventilation shaft V of the "Pniówek" coal mine – in 2007; replacement of the elevation sheathing of the "Ludwik" shaft tower – in 2010; removal of the consequences of breaking and falling of the power cable into shaft II of the "Zofiówka" coal mine – in 2014. A very complicated task carried out by the high-altitude team were the works performed in 2016 in shaft V of the Pniówek coal mine. The safety works in the shaft were carried out by a high-altitude mine rescue team, instead of an external company, which saved money and time.
