摘要
针对地下金属矿山的岩层移动问题 ,以国内无底柱分段崩落法矿山为例 ,进行岩层移动规律调查分析。调查结果表明 ,由于地下金属矿床复杂多变的地质、采矿条件 ,使得采矿岩层移动预测存在很大的不确定性 。
In light of the rock stratum displacement problem of underground metal mines and with China's mines that use non pllar sublevel caving mining as example,the investigation and analysis of rock stratum displacement law were made.The results show that the various and complex geological and mining conditions of underground metal deposits have led to the great uncertainty in the prediction of the rock stratum displacement of mining.There exist various differences between the rock stratum displacement angle designed and that in practical mining.
