Classification method study of joint coal fracture based on Hoek-Brown criterion 作者: Zhang, LS (Zhang Lisong)1; Yan, XZ (Yan Xiangzhen); Yang, XJ (Yang Xiujuan) 編者: Xie, F 來源出版物: ROCK STRESS AND EARTHQUAKES 頁: 447-452 出版年: 2010 被引頻次: 0 (來自 Web of Science) 引用的參考文獻: 9 [ 查看 Related Records ] 引證關(guān)系圖 會議名稱: 5th International Symposium on In-Situ Rock Stress 會議地點: Beijing, PEOPLES R CHINA 會議日期: AUG 25-27, 2010 會議贊助商: Int Soc Rock Mech; Inst Crustal Dynam China Earthquake Adm; Chinese Soc Rock Mech & Engn; Seismolog Soc China 摘要: Calculation formulas of geological strength index(GSI) and jointing parameter(JP) of rock strength index(RMi) are derived, and the GSI-JP modified analysis method for coal fracture in wellbore direction is given. Considering wavelet neural network, coal principal stresses with reservoir plane is analyzed, consequently coal seam plane fracture classification method is presented based on Hoek-Brown criterion. According to GSI-JP value, coal seam fracture coefficient size and energy method, four grades of A,B,C,D are divided for coal fracture degree at wellbore direction and reservoir plane, and coal fracture classification stan-dard is determined. Appling the classification method and standard, the distribution regularity of coal fracture is studied for ZP-1 Well and JinCheng region in QinShui basin. The research results show that coal GSI value of ZP-1 well is among 30-50, and JP value of RMI is 0.1-0.25, so coal fracture of ZP-1 is considered as grade B. Coal seam fracture degree of YangCheng, DingDian, FanZhuang, FanZhuang, ChangYe, ZhangZi in JinCheng block is defined as grade A, but northwest region coal seam is belong to grade D. The prediction results agree well with the measured values, therefore the classification method and standard are proved. Depending on research results, computer program is corresponding developed. 入藏號: WOS:000290973700072 文獻類型: Proceedings Paper 語種: English 通訊作者地址: Zhang, LS (通訊作者),China Univ Petr, Coll Mech & Elect Engn, Dongying, Shandong, Peoples R China 地址: 1.
