    (Wydawnictwa AGH, 2010) Glapa, Wojciech; Stefanicka, Mariola
    This paper, basing on the example of the basalt quarry, describes various issues related to increasing the quantity of the resources of exploited mineral deposits, change of property concentration, management activities and the types of products offered in the period of economic transformation in the years 1989-2009. State of important geological-mining assets especially connected with changes of: resources of deposits (documentation of deposits, purchase of quarry), restructuring of machinery, implementation of innovative technologies and activities for natural environment were described. In the results of these changes, new qualitative mineral aggregates by PN-EN standards are being produced and supply on the market. Lusatian Basalt Quarry »Księginki« JSC in Lubań was established in 2001 as a worker cooperative, in the result of privatization of state-owned undertaking. Currently, productive activity in three quarries operating on the deposits: Księginki Północ, Księginki I and Bukowa Góra (total basalt reserves about 123 Mt) is being realised.

    Nieczynny kamieniołom bazaltu w Strzegomiu - szansa na nowe otwarcie
    (2010) Tokarczyk-Dorociak, Katarzyna; Skolak, Krzysztof; Lorenc, Marek Wojciech
    The paper presents the history, current state and possible future protection, and development of the open-cast mining heritage. An example is the abandoned basalt quarry in Strzegom known under official name »The Żółkiewka Quarry« although local community uses rather the term »basalt quarry«. The rock is an Early Miocene alkaline basalt of K-Ar isotopic age 19.84 - 0,93 Ma. Mining operations had lasted from the XlXth century until 1986. The plans are currently prepared to adapt the quarry for local community and for tourism by development of geological thematic trail and construction of educational infrastructure.
