摘要
在对尾矿库回采区域进行网格划分的基础上,规划回采条带和回采线路,形成以排洪井所在横剖面为起点,分别向上下游波形啮合推进的回采策略,同时提出了各回采线路回采能力的计算方法,以及回采边坡安全和排水措施。以具体工程为例对提出的回采方法进行了验证,结果表明本方法可消除回采机械之间的相互干扰,有效提高回采效率;同时可对回采能力进行精确计算,便于施工管理。
On the basis of meshing recovery area,design recovery stripes and recovery routes,forming the recovery strategy of starting from the cross section of flood shaft,advancing respectively upward and downward in wedge and wave shape,and at the same time put forward calculation formula of recovery capability of each route,and slope steady and draining measures during recovery process.The method is then verified by a specific engineering case,the results show that this method can eliminate interference of recovery machines,prominently boost recovery efficiency,and calculate precisely of recovery capability,which is good for recovery management.
