摘要
根据金川二矿区多中段多盘区同时回采的实际情况 ,采用FLAC数值软件对 7种回采顺序进行了数值模拟 ,结果表明 ,从矿体一端向另一端渐进式下降的回采顺序 ,有助于改善二矿区回采区域的地应力条件 ,减小塑性区面积及围岩的移动。
According to the actual situation of multi-level and multi-panel mining at the same time in No 2 mine area of Jinchuan company.The FLAC program is adopted to simulate seven kinds of mining sequences. It is concluded that progressive mining from one end panel to the other end panel along the strike helps to improve No 2 mining area's deep stress distribution, reduce the plastic zone, and control the vertical displacement of wall rock. Some suggestions are put forward for adjusting the mining sequence of No 2 mining area in the future.
