摘要
本文以高原低山丘陵地貌的11607浅埋深工作面工程背景,进行了工作面开采过程中上覆岩层导水裂隙带高度发育研究,通过现场实测、相似模拟结合数值模拟的方法,研究了采动影响下,覆岩破坏变形规律,导水裂隙带发育高度等特征,三种方法所测得结果相互得到了验证,该项研究对山区内覆岩导水裂隙带发育规律研究起到一定参考借鉴意义。
In this paper, the background of 11607 shallow buried deep working face with low mountain and hilly terrain, the research on the height development of the water-bearing fissure zone in the overlying strata during the mining process is carried out, and the characteristics of the failure deformation law of overburden rock and the development height of the water-conducting fissure zone are studied by the method of field measurement, similarity simulation and numerical simulation. The results obtained from three methods have been verified by each other,and the study has been used for reference for the study of the development regularity of the water-conducting fissure zone in the mountainous area.
