摘要
在对矿岩石及矿石进行力学实验的基础上,对其地压分布规律进行了三维数值模拟分析,找出了该矿区地压分布规律,对该矿区部分矿体回采顺序进行了优化模拟,同时,对东西区结合带地压和巷道变形规律进行监测,监测结果表明采用优化的回采方案后采场应力集中程度降低了,采场地压得到了有效的控制,采区巷道也比较稳定,保证了矿山安全生产.
On the basis of the mechanical experiment of rocks and minerals in the ore,ground pressure distribution of the three dimensional numerical simulation were analysed,the distribution of ground pressure in the mine were obtained,some ore of mining sequence is optimized and simulated,while combined with a land area of things pressure and roadway deformation monitoring,which is caused by twoavalanche zone.The stress concentration of the rock mass between the two avalanche zoneis is very high,which cause the mining geostatic pressure abnormality of the stope under the rockmass.Therefore,it is necessary to study the geostatic pressure distribution law and the control measures for ensure the safety production geomechanics.
