摘要
为了得到斜沟煤矿18104工作面"两带"的高度,采用理论计算、现场实测和数值模拟的方法,研究分析18104工作面覆岩裂隙发育的演化规律,通过孔巷三维测试方法实测"两带"高度验证理论计算和数值模拟结果的准确性。研究结果表明:18104工作面垮落带高度是9.5 m,断裂带高度是34.7 m,现场实测结果与数值模拟结果基本一致,而理论计算得到的断裂带高度明显偏小;同时得出,FLAC3D模拟方法是采动覆岩"两带"高度研究的有效手段;研究成果为类似条件矿井水灾和瓦斯治理提供了一定的依据。
In order to obtain the height of two zones in 18104 lace of Xiegou coal mine, theoretical calculation,field measurement and numerical simulation are used. The evolution law of overburden fracture development in the lace is studied and analyzed. The accuracy of theoretical calculation and numerical simulation result is verified by measuring the height of two zones by three dimensional test method. The results show that the height for collapsed zone is 9.5m and the height for fault zone is 34.7m. The field measured results are basically consistent with the nu- merical simulation results, but the height of the fault zone calculated by theoretical calculation is obviously smaller
