    Wydział Geologii, Geofizyki i Ochrony Środowiska
    Celem projektu inżynierskiego jest omówienie norm z rodziny ISO 14000, w kontekście działalności organizacji. Przedstawione zostaną normy: ISO 14001, ISO 14015, ISO 14031 oraz ISO 14040. Każda z nich dotyczy innego zagadnienia związanego z zarządzaniem środowiskowym. Przy ich powstawaniu przyświecała idea, aby zminimalizować negatywne oddziaływanie organizacji na środowisko. Dotyczy to zarówno wszystkich działań jak i wyrobów przez nią wykonywanych. W wyniku wdrażania norm z serii ISO 14000, organizacja w sposób pośredni lub bezpośredni czerpią z tego wymierne korzyści.

    Stress state and bearing capacity of shallow tunnel linings undergoing the influence of nearby located buildings
    (Wydawnictwa AGH, 2005) Fotieva, Nina; Bulychev, Nikolay; Sammal, Andrey; Deev, Petr
    The paper describes a new analytical method of designing shallow tunnel linings of an arbitrary cross-section shape undergoing the influence of buildings both erected nearby the already existing tunnel and constructed before the tunnel driving. The method is based on analytical solutions of the corresponding elasticity theory plane problems for a heavy semi-infinite medium weakened by a supported opening. The approximate technique is proposed for taking the 3-D character of problems into account caused by limited sizes of buildings in the direction along the tunnel axis and by the location of several buildings on some distances between them in this direction. It gives a possibility to determine the stress state and evaluate the lining bearing capacity in different cross-section along the tunnel axis. Example of the design are given.

    Wpływ wewnętrznego rąbka zwornika przewodu na przepływ płynów wiertniczych
    (2007) Bednarz, Stanisław; Knez, Dariusz
    Drill pipes called drill rods as an essential part of the drill string are used in horizontal directional drilling. The application of frictional welding is the most common method in plain pipes and tool joints connection. The outside and inside surfaces flash at the ends of parts joined arises after this operation as a result of high contact force, simultaneous rotation of tool joint and high temperature in accordance with the materials melting. The outside surface flash is removed by cutting method, however big problems are encountered during removal of the flash inside of the pipe. The paper concerns the influence of the internal flash on the drilling fluid flow during making the hole. The ununiform flash shape creates difficulties in the analytical description of this phenomenon. According to this, computer simulation appears to be a very effective tool for solving this problem. Friction losses and velocity vectors field in the flash zone are evaluated on numerical calculations basis.

    The objective of the research under consideration is subterranean waters contamination state of Dombrovsky quarry of Kalush from the launching dates of its exploitation to nowadays. The evidences of an inappropriate exploitation and eco-unfriendly methods of quarry management are depicted. The goals of this research are Dombrovsky quarry hydrogeological environment analysis in terms of modern and historical potassium production of Kalush industrial center with a geo-technogenic system formed. The research reveals an attempt to display the basic factors that negatively influence the environment in terms of long-term polymineral salt extraction and reprocessing. Tracing of process developing mechanisms and tendencies investigation are under consideration. In order to prevent an ecological disaster Antratsit-Plus Ltd. technology is considered to be introduced for Dombrovsky quarry north side area. Antratsit-Plus Ltd. technology is designed for dangerous substances contamination prevention by means of subterranean hydro isolation of open pits, quarries, salt dumps, open and subterranean dangerous and toxic substances depositories, brines and acid waters by means of using absorbing bentonite-cement solvent as packing material.
