摘　　要：针对西部风沙区高强度开采动态地裂缝发育特征监测难点以及现有技术存在的问题,开发了一套采动地裂缝发育周期的监测装置,文章详细阐述了装置的组成、使用方法以及数据的处理方法。该装置在补连塔12406工作面进行动态地裂缝监测,监测结果表明,高强度开采动态地裂缝扩展的程度和时间相对较小,在垂直方向上无显著落差,在水平方向上的相对位移呈现两个时长近似"开裂—闭合"的发育周期,地裂缝的发育特征与过程进一步验证了高强度快速开采地表移动变形的特点。Aiming at the difficulties and technical problems in dynamic ground fissure development characteristics monitoring in the windy and sandy region with high intensity coal mining, a new monitoring device was invented, and the operating method and data processing technique was detailed. The device was applied in 12406 working face of Bulianta mine. The result shows that, the expansion degree and expansion time of dynamic ground fissure caused by high tension coal mining are smaller than before, without obvious heads in vertical direction, while the width shows two ＇cracking- closure＇ stages, with approximate equal durations. The development process and characteristics of the dynamic ground fissure further verify the characteristics of surface movement and deformation caused by high intensity and rapid coal mining.
