摘要
超高水充填开采是近年来发展迅速的绿色开采技术,但对其引起的地表沉陷及预计参数的确定仅有较少的研究。通过建立地表岩移观测站,及时准确获取观测资料,对观测结果进行了分析计算。通过实测数据与预计数值的拟合,获得了某矿超高水充填综采基于概率积分法的岩移预计参数,并对导致地表产生明显移动和变形的影响因素进行了探讨。
Ultrahigh water fill mining is one of the green mining technologies,developed rapidly in recent years. There were few studies about the surface subsidence and prediction parameters caused by this technology. The rock move monitoring stations were set up to obtain the accurate observation data. Based on these data,the prediction parameters of probability integral method was obtained by fitting the measured datas and the predicted datas. At last,the influencing factors which caused the obvious surface movement and deformation were disscussed.
