Equipping the Schwind shaft with a vertical transport device
(Wydawnictwa AGH, 2019) Zuski, Zygmunt; Pasek, Rafał; Rożenek, Zenon
The article presents the construction of an inter-level shaft between levels II lower and level III and equipping it with a transport system. The purpose of the project was to provide transport of loose materials and long items from level III to level II lower, which was necessary to secure the mining excavations. Before the investment, only a limited amount of materials could be transported manually by means of ramps.

Thesis concerns the quantitative interpretation of the vertical distribution of gravimetric survey. Discusses the theoretical basis of research in mining shafts, and shows the method of calculating the density interval. The possibilities of using gravimetric measurements to update the old geological data. Shown the possibility of using distributions of anomalies to determine the physical parameters of body disturbing, which include thickness, density and range horizontal. Also presented how the individual parameters affect the shape of the curve anomalies.

In the case of occurrence of substantial rock mass pressures on a shaft lining practically impossible is protect a shaft breakout with the aid of the typical construction of a rigid lining. Especially large pressure can occurs in the case of shaft driving through the thick layers of salt, where on the great depth, primary vertical stress exceeds the strength of salt. Increased rock mass stresses also should be taken in to consideration in the case of influence of deformation generated by mining exploitation. The paper presents the constructional solution of shaft lining by make use its load capacity to braking creep of rock mass just after moment of its execution and the solution of lining making possible creep of a shaft cheek with maintain a constant diameter of shaft.

Ocena wskaźnika nośności CBR dla wybranych gruntów spoistych i sypkich
(Data obrony: 2010-03-10) Rudzka, Joanna
Wydział Geologii, Geofizyki i Ochrony Środowiska
The aim of these master’s thesis is the evaluation of California Bearing Ratio two cohesion soils (loam, silt) and one cohesion less (sand). Thesis contains three parts. First part brings the base and methods of sign the evaluation of California Bearing Ratio. In second part presented performed research of the basic physical parameters of soils. The last fragment presents laboratory part of subject (topic) with calculations and conclusions from conducted research, where focused on the swelling cohesive soils and determination the evaluation of California Bearing Ratio for individual soils. On the basis of the results obtained it was possible to determine whether the ground test can be used in road construction as a material incorporated into embankments or shaft.

Przedsiębiorstwo Budowy Szybów - nietypowe zadania w budownictwie szybowym
(2007) Rusek, Janusz; Sanocki, Tomasz
In December 2003 Kopex SA concluded a Contract for main shaft deepening, construction and furnishing of support excavations at Cayeli Bakir Isletmeleri Zink and Copper Ore Mine in Turkey. From December 2003 till August 2007, PBSz SA carried out complete work in mining and mechanical branches, within the confines of a project consisting in opening-out a new production level. The scope of work included: deepening by 286 m an operating production shaft of 5.5 m diameter, construction and furnishing of shaft station room, skip pocket, conveyor drift, electric substation room and main pump room on the new production level, sinking of oblique ore passes and a ventilation raise, driving approx. 1000 m of stone headings with the application of shotcreted anchor support. During the shaft and ore pass sinking, the construction of support structures and driving of headings procedure employing the techniques of large diameter hole drilling and blasting were applied at a wide range. The procedure applied allowed the carrying out non-standard tasks in shaft construction.

The concept of applying the shaft inclinometer in verticality and rectilinearity measurements of shaft guides
(2008) Skulich, Mikołaj
Artykuł przedstawia budowę, zasadę wykonywania pomiaru oraz wstępne wyniki badań prototypowego urządzenia o nazwie inklinometr szybowy, służącego do określania prostoliniowości i pionowości prowadników szybowych. Przedstawiona technika pomiarów z wykorzystaniem inklinometru szybowego ze względu na swoje bezpieczeństwo i krótki czas pomiaru może stanowić propozycję alternatywną dla stosowanych obecnie klasycznych metod inwentaryzacji prowadników w szybach górniczych.
