【摘要】：構(gòu)造煤發(fā)育是發(fā)生煤與瓦斯突出的必要條件,常規(guī)構(gòu)造煤識別方法存在效率低和準(zhǔn)確率低等缺點(diǎn).本文以蘆嶺煤礦Ⅱ六采區(qū)8煤層為研究目標(biāo),利用不同結(jié)構(gòu)類型煤體的測井響應(yīng)特征不同的特點(diǎn),識別煤層中不同結(jié)構(gòu)類型煤體.為了提高識別準(zhǔn)確性,利用小波多尺度分析方法提取測井曲線中的低頻分量和中頻分量;再以低頻分量和中頻分量為輸入,利用聚類分析法劃分不同結(jié)構(gòu)類型的煤體.通過識別,可以明顯區(qū)分出目標(biāo)層的原生煤、碎裂煤、碎粒煤和糜棱煤等四種結(jié)構(gòu)類型煤體,同時(shí)也可以識別出煤層中的夾矸.以研究區(qū)中多鉆孔識別的煤體類型為基礎(chǔ),繪制煤體結(jié)構(gòu)三元相圖,并將研究區(qū)劃分為Ⅰ、Ⅱ、Ⅲ和Ⅳ等四類煤體結(jié)構(gòu)組合類型區(qū)塊.其中,Ⅲ類組合區(qū)塊中構(gòu)造煤最為發(fā)育,是煤與瓦斯突出的重點(diǎn)防治區(qū).
[Abstract]:The development of tectonic coal is a necessary condition for coal and gas outburst, and the conventional structural coal recognition method has the disadvantages of low efficiency and low accuracy. In this paper, the target of this study is 8 coal seams in No. 2 sixth mining area of Luling Coal Mine. Different structural types of coal bodies are identified by using the different characteristics of logging response of different structural types of coal bodies. In order to improve the accuracy of identification, wavelet multiscale analysis method is used to extract the low frequency component and intermediate frequency component in the log curve, and then the low frequency component and the intermediate frequency component are used as input, and the cluster analysis method is used to divide the coal bodies of different structure types. Through the recognition, the coal bodies of primary coal, broken coal and mylonian coal can be distinguished obviously, and the gangue in coal seam can also be identified at the same time. Based on the type of coal body identified by multiple boreholes in the study area, the ternary phase diagram of coal body structure is drawn, and the study area is divided into four types of coal structure combination blocks: 鈪，
