Abstract
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.关键词
