摘　　要：煤层的开采极易导致采动裂隙直接连通地表,引起煤层自燃、地下水流失等灾害现象。掌握煤层上表岩层中裂隙发育特征,是解决上述问题的基础。将氡测量技术引入到煤炭采动裂隙发育研究中,通过实验模型模拟,分析得出了沙基型煤层采动裂隙分布与氡气浓度之间的相关规律。Coal production in seam mining can easily lead fracture in overlying stratum link up to the surface cracks directly, which could cause combustion, loss of groundwater and so on. An important basis to effectively solve the problems is to grasp the characteristics of distribution of mining fracture in overlying stratum. Radon measurement is introduced into researching on fracture development of seam mining,and the correlation of fracture and radon concentration in seam mining is analyzed by experimental simulation.
