中文摘要：
结合新城金矿开采实际,设计顶板岩移监测方案,分析监测数据,并进行岩移变形时间序列预报。采场顶板监测表明：每2 d岩移量在-2.00～2.00 mm之内,100 d累计岩移量不超过20.00 mm;最大岩移量位于顶板中心,最小岩移量位于采场两帮;岩移量沿采场走向呈现出先增后减的规律;岩移量随时间逐渐趋于稳定,顶板累计岩移量不超过25.00 mm;矿山目前支护方式可确保采场安全;采场支护应在岩层应力完全释放前进行,锚杆网度应根据现场情况适当加大。
英文摘要：
According to mining condition of Xincheng Gold Mine,the monitoring scheme for roof displacement was designed and the results data were analyzed,and then the time series predicting analysis for roof support was made.The results show that the rockbody movement value range from-2 mm to 2 mm every 2 d,with an overall change of 20 mm for 100 d.In the same drift section,the maximum value of roof rock movement amount appears frequently at the middle point and the minimum in the stope’s sides.Along the stope trend,the movement value increases at first and then decreases.Cumulative rock movement amount gradually tends to be in equilibrium,with a maximum value of 25 mm.Based on the results of roof movement monitoring and prediction,the existing support way can effectively ensure that the safety and reliability of the stope roof shall be obtained.It is advised that roof support should be taken before stress release is finished and that the support netextent should be increased according to the practical situation on site.
