免费网络研讨会：在不稳定的地质下获得稳定的掘进
如果在混合地质条件下进行隧道施工，隧道横截面上可能存在任何岩土组合，那么您预计该项目将是一个挑战。当变异性是一个常数时，诸如地表沉降、掘进机上的磨损和适当的地质加固是一个问题。尽管存在这些变量，您的项目仍然可以成功。采用正确的技术、人员和操作方法，即使在最可变的地质条件下，也可以实现持续的良好掘进率。
罗宾斯副总裁Doug Harding和工程师Greg Michaelson将在这场免费的60分钟网络研讨会上探讨混合地质的情况，深入研究盾构机和跨模式掘进机在该领域的最新案例研究。Harding和Michaelson将根据我们众多现场服务人员的经验，根据成熟的设计和方法提出建议。无论你是一个操作掘进机的承包商，一个指定设备的顾问，还是一个即将开始的项目的业主，在不同的地质条件下，持续良好的挖掘都是可能实现的。

免费网络研讨会：如何通过挤压地质、岩石破碎等
如果你曾经面对过穿越重山的隧道条件，那么你知道面对未知是什么。大多数深埋高覆隧道都会遇到一些意想不到的情况，无论是断层带、挤压地面还是岩石爆破。如果没有适当的规划、施工经验和掘进机设计，这些挑战可以迅速阻止掘进机在其路径上掘进。从可以有效避免卡住盾体的严重地质，到可以损害掘进机的高压超挖，开挖重山隧道可以掘进的十分迅速。
那么，当情况变得困难时，如何保持隧道掘进机的掘进？与我们的隧道专业人士共度60分钟，在这场免费网络研讨会上学习最好的东西，这是我们2018年系列的第一次。通过实际案例研究，我们将讨论几十年来在现场隧道施工中遇到的一些最困难的条件。了解如何克服障碍，同时尽量减少停机时间，确保施工人员的安全。

免费网络研讨会：降低风险如何管理掘进机隧道中的未知状况
让我们面对现实吧：隧道工程本身就具有风险。即使经过严格的测试，即使是一家高资质的咨询公司创建了岩土基线报告，实际的地质情况也可能存在不可预见的情况。在掘进机掘进的隧道中，机器和操作机器的人员是风险管理策略的关键组成部分。那么，我们如何才能确保隧道作业尽可能地有效地进行呢？
从制造商的角度来看，罗宾斯的首席工程师Dennis Ofiara和项目工程师Elisa Comis将在这60分钟的免费网络研讨会上探讨这个问题，深入探讨合同结构、掘进机设计、案例研究等，以找到答案。无论你是一个操作掘进机的承包商，一个指定设备的顾问，还是即将进行项目的业主，即使是最复杂的隧道也有可能降低风险。

免费网络研讨会：压力下的表现
土压力平衡盾构机（EPB）是目前隧道工程中应用最广泛的一种掘进机，但其在不同地质条件下的合理设计和使用却不常被讨论。粘土、砂、砾石、混合面条件和巨石都需要独特的盾构机设计和专家操作。无论这意味着利用耐磨电镀，重型螺旋输送机，或定制切割工具，今天的盾构机都面临挑战。在操作方面，使用正确的转速、适当的添加剂和详细的监测可以使沉降保持在最低限度，减少停机时间。
在这场免费的60分钟网络研讨会上，罗宾斯工程经理Brad Grothen和罗宾斯盾构首席工程师Shinichi Konda将探讨盾构机的工作原理、各种设计和现实应用。他们将从多种地质类型的现场数据中提取数据，对盾构机的设计和操作提出明智的建议。还将讨论“包括高刀具磨损和适当形成插头的能力”。

免费网络研讨会: 了解您前方面对的是什么。
无论挑战是深埋深、挤压地质、断层带还是涌水，您的项目都必须继续前进。新的地面调查和处理方案可以为您提供工具，以克服您所面临的问题，同时最大限度地提高掘进机性能和安全性。
在这场免费的60分钟网络研讨会上，罗宾斯首席工程师Dennis Ofiara将讨论困难的地质解决方案（DGS），这是一套可用于盾式硬岩石和跨模式掘进机的选项，可使机器在长隧道、深埋深和具有挑战性的地质特征中移动。DGS是关于可视化的：机器的盾体不必阻挡你对周围地面的观察。有了360度长距离超前钻机、收敛测量传感器（提醒操作员挤压地质）和拱顶钻机（用于加固地质）等一系列功能，您可以清楚知道下一个冲程您会遇到什么挑战。

免费网络研讨会: 拥有一台掘进机的总成本？
Subject: What is the Total Cost of Owning a TBM?

Tunnel Boring Machines exist today that have excavated over 50 km (31 mi) of tunnel, and have been in operation for nearly 50 years. These workhorses have been built and rebuilt to satisfy requirements of various tunnels while their durable steel structure endures.
Today’s underground construction contractors often face a higher capital cost during the initial investment for a TBM, but what is the total cost of owning a TBM? Much more than the initial price tag must be taken into account: while a heavier TBM with durable steel structure may cost more initially, reusing it on multiple tunnels will ultimately result in substantial savings. Paying for a custom-designed machine often results in increased efficiency and faster advance rates, with the end result that the tunnel is completed on or even ahead of schedule.
In this complimentary 60-minute webinar, Robbins Vice President-Sales Doug Harding will explore the true cost of owning a TBM, considering the entire lifespan of the machine. He will draw on real project data and cost estimates to demonstrate that a machine designed for multiple tunnels will pay for itself over time.
We invite you to submit your questions beforehand webinars@robbinstbm.com to get a thoughtful and well-researched answer from Doug during the Q&A session at the end of the webinar.

Today’s mine development projects are no longer being done from the surface. Worldwide, easily accessible ore deposits have been spent, requiring mines to aim for deeper ore bodies, often kilometers underground, to keep operations viable.
This changing mine environment brings a need for access tunnels, first to reach the ore, then to provide long-term muck haulage. Tunnel boring machines provide efficient, safe, and fast access to those ore bodies. Mines around the world are accustomed to methods such as drill & blast, roadheader, and other types of conventional excavation. However, TBMs have been proven on multiple projects to complete tunnels two to three times faster than drill and blast; when considering roadheaders that number is often 10 times faster.
In this complimentary 60-minute webinar, Ryan Gratias, Project Engineer at Robbins and Adam Foulstone, General Manager-Grosvenor for mining company Anglo American, will discuss the changing face of the worldwide mining industry. From machine design to application and real-world examples, Gratias will prove that early adopters of the TBM method will be able to better meet increased demand and extend the life of their mine. Foulstone will discuss the recent use of a Crossover (XRE) TBM at the Grosvenor Decline Tunnel in Australia™ wildly successful use of a TBM that resulted in access tunnels bored 14 times faster than the traditionally-used roadheader method.

In the modern-day tunneling industry, one outdated perception remains: Traditional, tested methods are always the best. When presented with difficult ground””from fault zones to water inflows to mixed face conditions””many consultants and contractors rely on decades-old field studies and conclude that conventional excavation methods like drill and blast are the best option. With today’s Tunnel Boring Machine (TBM) technology, this assumption couldn’t be further from the truth. Modern TBMs are highly adaptable and capable of offering all of the same ground support and excavation capabilities of their conventional counterparts””most often with a safer setup and faster performance, not to mention at a lower overall cost.
In this complimentary 60-minute webinar, Robbins President Lok Home will analyze recent tunneling projects in difficult ground conditions where TBMs have proven their worth, including Turkey’s Kargi Kizilirmak Hydroelectric Project and Peru’s Olmos Trans-Andean Tunnel. At Kargi, a shielded hard rock TBM overcame incredibly difficult mixed face conditions with the help of in-tunnel machine modifications””ultimately completing the tunnel at an advance rate more than twice that of a drill and blast operation proceeding from the opposite end of the tunnel. At Olmos, the world’s second deepest civil works tunnel, a TBM ultimately succeeded at boring where drill and blast had failed: below 2,000 m of volatile volcanic rock in the Andes Mountains.
