【摘要】：基于貴州盤江礦區(qū)生產(chǎn)地質(zhì)條件的復(fù)雜性,為了解決因地質(zhì)構(gòu)造查明程度較低引起的煤礦安全生產(chǎn)問題,采用灰色模糊綜合評價(jià)法,對盤江礦區(qū)煤系地質(zhì)構(gòu)造復(fù)雜程度評價(jià)進(jìn)行了研究,提出了一種地質(zhì)構(gòu)造復(fù)雜程度評價(jià)方法。研究結(jié)果表明:將12號煤層劃分為65個(gè)評價(jià)單元,其中地質(zhì)構(gòu)造復(fù)雜程度評價(jià)結(jié)果為Ⅰ、Ⅱ和Ⅲ級的評價(jià)單元分別有18,7和40個(gè),且垂向分布明顯。評價(jià)結(jié)果與生產(chǎn)實(shí)際過程中已揭露的情況基本吻合,結(jié)合備采區(qū)域的瓦斯含量和瓦斯涌出量特征,有助于該區(qū)域的瓦斯災(zāi)害防治決策。
[Abstract]:Based on the complexity of production geological conditions in Panjiang mining area, Guizhou province, in order to solve the problem of coal mine safety production caused by low degree of geological structure identification, the grey fuzzy comprehensive evaluation method is adopted. The evaluation of the complex degree of coal measures geological structure in Panjiang mining area is studied, and a method for evaluating the complexity of geological structure is put forward. The research results show that the No. 12 coal seam is divided into 65 evaluation units, in which the evaluation results of the geological structure complexity grade 鈪，
