充填开采条件下上覆岩层变形移动特征不同于全部垮落法,为了获得其上覆岩层变形移动特征的差异,以邢台矿7608充填开采工作面为试验背景,采用相似材料模拟工作面回采和充填过程,采用三维静态变形测量系统对上覆岩层进行了变形观测。通过对比充填率为90%和0时2种不同情况,获得了充填法和全部垮落法管理顶板条件下上覆岩层变形移动特征和充填对覆岩移动的影响规律。
Under the conditions of filling and mining, the deformation and movement characteristics of the overlying strata are different from those of the full caving method. In order to obtain the difference of the deformation and movement characteristics of the overlying strata, taking the Xingtai Mine 7608 filling working face as the experimental background, the similar materials are used to simulate the face mining and filling Process, using the three-dimensional static deformation measuring system overlying strata deformation observation. Through the comparison of filling rate of 90% and 0, the influence of filling and overburden on the movement of overlying strata is obtained under the condition of filling method and full collapse method.
