Simply monitoring movement of the tailings dam wall does not address the cause of tailings dam failures and will therefore never be an effective method to reduce or prevent failures. Monitoring the causes of failures is more effective. The main cause of tailings dam failure is slope instability, which is caused by too much water in the wrong place. Accurate pore pressure monitoring of the pressure (weight) of water in the tailings storage facility (TSF) slopes and plotting of flow lines beneath and upstream of the TSF can guide and enable early intervention to prevent or delay failure. Remote monitoring linked to artificial intelligence and robotics to turn on pumps and open drains to address and remove the cause of failure can help reduce risk. Installation of multiple point piezometers in an accurate pattern allows the plotting of equipotentials and flow lines in three dimensions. Each TSF is unique and requires its own monitoring design, which should be tailored to match the age, structure, and specific causes of risk. Once understood, the monitoring system can be coupled to a reporting system to significantly reduce the risk of failure at both legacy and active sites.

使用精确的孔隙压力监测降低尾矿坝风险

简单地监测尾矿坝墙体的运动并不能解决尾矿坝故障的原因，因此永远不会是减少或防止故障的有效方法。监控故障原因更为有效。尾矿坝溃坝的主要原因是边坡失稳，这是由于放错地方的水过多造成的。对尾矿库 (TSF) 斜坡中水的压力（重量）进行准确的孔隙压力监测，并绘制 TSF 下方和上游的流线图，可以指导和实现早期干预，以防止或延迟故障。与人工智能和机器人相关的远程监控以打开泵和打开排水管以解决和消除故障原因，有助于降低风险。以精确模式安装多点测压计允许在三个维度上绘制等电位和流线。每个 TSF 都是独一无二的，需要自己的监控设计，该设计应根据风险的年龄、结构和具体原因进行定制。一旦了解，监控系统可以与报告系统相结合，以显着降低遗留站点和活动站点的故障风险。
