  • 25 years of "Safety at Work and Environmental Protection in Mining
    One of the statutory tasks of the President of the State Mining Authority, resulting directly from the provision of art. 166 sec. 1 point 5 of the Act of 9 June 2011 - Geological and Mining Law, there are promotional and information activities in the scope of issues covered by the material competence of mining supervision authorities. Although in various words and acts of different rank, it has been mentioned in mining regulations since 1954, when, in § 10 of the Annex to Resolution No. 612/54 of the Council of Ministers, among the tasks of the Scientific and Technical Mining Council operating at the time of the President of WUG , listed, among others "issuing opinions on the plans and scope of publishing and popularizing activities regarding health and safety at work and the sound management of deposits ...".
    The promotion of occupational safety and health as well as environmental protection (including mineral deposits) in mining in the activities of the State Mining Authority takes various forms, cross-sectionally characterized earlier in the work. One of them is a variety of publications, and among them, first of all, the scientific and technical journal "Work Safety and Environmental Protection in Mining." The president of WUG has been publishing it continuously since 1992, so simple arithmetic makes him aware that he has already finished 25 years! It seems that this is a good opportunity to recall its roots, evolution and achievements, and above all, the people who created it.
  • Coefficient of exploitation, and type of rock mass
    The article presents the analysis of the value of the exploitation coefficient carried out for the conditions of exploitation of coal seams in the Upper Silesian Coal Basin. The areas assessed were characterized by the use of the same system of exploitation with a roof failure, but with different geological conditions. The rock mass was characterized by the thickness and type of the overburden layer, the type of carboniferous layers, the depth of exploitation and the degree of violation of the rock mass by previously performed exploitation.
  • British experience with a self-supporting anchor housing
    In the article, based on the Golder Associates study, a summary of British experiences related to the application of anchoring technologies in coal mines from 1987 to 1994 (British Coal privatization) and work done by Rock Mechanics Technology team members, their role and leadership experience was presented. this change, including organizational and technical obstacles, how they have been overcome, the technology used and the efficiency and safety benefits achieved. The article discusses in general the fundamental principles of designing a self-contained anchor housing, a way of monitoring and monitoring excavations to ensure safety and indicates what geotectonic and rheological conditions should be taken into account when planning a hard coal deposit to be able to successfully use an independent anchor housing in the excavation workings.
  • Management of surface failures in mining areas in the process of qualification of industrial resources (Discussion article)
    The article describes the management of mining in mining areas of underground mines by qualifying mineral resources for industrial purposes using the elements of the description of failures in the hydromorphological and cartographic method of assessing the threat of unpolluted mining areas. They allow for the mining resources of these parts to be allocated to mineral resources whose mining exploitation does not cause excessive pitting of the land surface.
