金川矿区有２５％以上的不良岩层，二矿区节理发育，在过去的开采工作中发生了许多冒顶灾害，威胁井下工人和设备安全，影响矿山正常生产。因此采用声发射技术进行监测，并建立相应的采场冒顶预测预报模式
There are more than 25% of bad rock formations in Jinchuan Mine Area. The joint development in No.2 mining area has caused many roof disasters in the past mining work, threatening the safety of underground workers and equipment and affecting the normal mine production. Therefore, the use of acoustic emission monitoring technology and establish a corresponding stope forecasting forecasting model
