摘要
传统铜矿开采方法不合理会致铜矿出现很多不明空区,铜矿开采过程中空区受到采动、时间等因素的影响,易导致空区围岩出现破坏,降低边坡稳定性,不利于铜矿开采作业的安全进行。以乌努格吐山铜钼矿为例,通过3DEC软件模拟分析对矿含空区边坡稳定性进行分析,以掌握空区边坡具体情况,为矿含空区安全开采提供支持。结果表明:对于不受空区影响的坡体,单空区和双空区边坡稳定性系数为1.10和1.128;对于受到空区影响的坡体,单空区和双空区边坡稳定性系数为1.079和1.092;铜矿边坡稳定性系数较高,符合相关规定要求,可保证该铜矿生产作业活动顺利开展。
The unreasonable traditional copper mining methods can lead to many unclear goaf in copper mines.During the copper mining process,the goaf is affected by factors such as mining and time,which can easily cause damage to the surrounding rock of the goaf,reduce slope stability,and be detrimental to the safe operation of copper mining.Taking Wunugetushan copper molybdenum mine as an example,the stability of the slope in the goaf was analyzed through 3DEC software simulation,in order to grasp the specific situation of the goaf slope and provide support for safe mining in the goaf.The results show that for slopes that are not affected by goaf,the stability coefficients of single goaf and double goaf slopes are respectively 1.10 and 1.128.For slopes affected by goaf,the stability coefficients of single goaf and double goaf slopes are respectively 1.079 and 1.092.The stability coefficient of the copper mine slope is relatively high,which meets the requirements of relevant regulations and can ensure the smooth operation of the copper mine production activities.
