摘要
滇池磷矿区大部分矿山进入深部或地下开采,迫切需要对露天高耸边坡的稳定性进行评定研究,以便开采工作的安全推进。以某磷矿为工程背景,采用FAHP模型对其边坡稳定等级进行评定。根据矿山地质条件及工程实际,选择10项影响因素作为指标层,选用岭形函数作为典型隶属度,同时辅以Karwowski推荐的模糊隶属函数来确定各影响因素的隶属度,采用一致矩阵确定各参数的权重,经模糊矩阵复合运算判断坡体稳定性水平,并结合工程实际进行对比。研究结果表明:该磷矿边坡稳定性为一般稳定,符合该边坡工程实际,需进行必要的预防措施。
Most of the mines in Dianchi phosphate mine area have entered deep or underground mining,so it is urgent to evaluate the stability of open-pit high slope for improving the safety of mining work.Taking aphosphate ore as an engineering background,the stability grade of its slope was evaluated by FAHP model.In the study,according to the geological conditions and engineering practice of the mine,10 influencing factors were selected as index level,and the ridge-shape function was selected as the typical membership degree.At the same time,the fuzzy membership function recommended by Karwowski was used to determine the membership degree of each influencing factor,and the weight of each parameter was determined by the consistent matrix.The stability grade of slope was judged by fuzzy matrix compound operation,and the result was compared with engineering practice.It was concluded that the slope stability of the phosphate ore was general stability,which was in line with the actual situation of the slope engineering,so necessary preventive work was needed.
