Drilling in Norway with 3D Rig Solution

Author: Arne Forsell

Rays of sunlight hit the wooded hillside from the west. The old road seems to lead upwards in an indefinite number of turns. The shadows are long. The water in the mountain lake is sparkling on the other side. The world’s highest ski jump slope with the steepest point of 200 metres peaks up from the woods, and snow-covered mountain tops can be seen on the horizon. We are in Vikersund, Norway, a few hours drive from Oslo, and the entire scene is glowing in autumn colours.

fjellsprenger as正在钻基岩进行地面准备，以建造一个围栏的建筑工地，在那里他们与另一家公司Norsk Fjellsprenger一起可以存储设备和炸药。该团队使用Leica Geosystems的3D机器控制解决方案进行了钻井工作。

Meeting the drill operator

弗莱登伦德（Frydenlund）在露面，从风化的手，令人印象深刻的胡须上牢固的握手，最重要的是带有矿工大灯的硬帽子 - 钻机操作员奇德（Frydenlund）正在展示自己。

Frydenlund与Drill Rigs合作八年，从E. Rolstad公司开始，现在在Fjellsprenger AS。在此之前，他担任挖掘机操作员。

他的机器是Sandvik Ranger DX800顶锤钻机。它的重量为15吨，在轨道上稳定，由卡特彼勒（Caterpillar）的225 hp电动机提供动力。Frydenlund可以用这台机器钻出直径为76至127毫米的孔。钻机配备了Leica iRD3用于钻井应用的机器控制解决方案，可帮助Frydenlund快速准确地完成工作。

弗莱登伦德（Frydenlund）是利物浦足球俱乐部（Liverpool FC）的粉丝，他喜欢赛车运动，在他的车库里，他的宝藏之一是：1981年以来诱人的栗色雪佛兰Corvette。

弗莱登伦德changes job sites frequently with his drill rig. Fjellsprenger AS is contracted for many different construction projects, and Frydenlund, as well as many of the company’s other machines, is moved between construction sites.

就在几周前，弗莱登伦德（Frydenlund）在挪威莫拉（Maura）的一处采石场（Quarly）的边缘将自己的钻机平衡。出于安全原因，能够从机舱外部远程操作机器并将机器固定在支撑土壤中非常重要。

在机器控制解决方案上的远程支持在悬崖上工作。

与他以前的工作网站相比，在维克森德的平面场上更容易。

对于某些在建筑行业工作了很长时间的运营商来说，像GNSS辅助机器控制这样的发明可能首次令人恐惧，但弗莱登伦德（Frydenlund）相反。

“I have experience with Leica Geosystems’ equipment already from my previous job,”说弗莱登伦德。“这使我的工作完全自由。如果我收到偏置高度，我可以在显示屏中构建钻头图案。这太容易了！然后，我可以准确地进行钻探。每个孔都钻出以正确的深度和角度的规格。我不需要测量师，一切都很快，后来易于从系统中导出的文档。”

Frydenlund迅速学习了如何使用新的3D机器控制系统操作钻机。

“我没有在学习系统方面遇到困难，如果我有的话，我宁愿称他们为挑战。”反映Frydenlund的学习经历。“You only need to be a little curious and interested, and then it is just like when you learned to ride a bike – once you have learned it, you don’t forget!”

弗莱登伦德reflects on the good relationship he has developed to Petter Heyerdahl, product manager for rig solutions at Leica Geosystems and his experience with Leica Geosystems’ personalised support team.

“我每周40个小时坐在这里的钻机中 - 这让您想到并获得新的想法！我已经与Petter讨论了我的想法和愿望。他听了我的话，我得到了我想要的大多数功能，”explains Frydenlund.

认识爆炸经理

Fjellsprenger的爆炸经理Magnus Hansen

The blast manager at Fjellsprenger AS, Magnus Hansen, lives close to the construction site, where the drilling is taking place. Close enough for him to take one of the fragmented rocks from the blasting and throw it to his house, if only he had enough strength in his arm.

汉森是室外类型。他对狩猎和钓鱼感兴趣。

汉森获得了岩石爆炸许可证 - 必须每五年续签一次许可证。他在该行业工作了14年。Blast Manager负责的任务包括对网站上工作的总体责任，并包括：

• safety
• 规划
• 环境问题
• 周围地区的考虑
• 交通关闭。

“We have increased productivity and the quality since we have started the cooperation with Leica Geosystem and since the machine control solutions are available,”explains Hansen.“我们不需要与以前相同的现场测量师，这可以节省我们的时间和成本。弗莱登伦德可以用钻机自己处理一切，并完全独立工作。”

“Once you have tried the solution, you simply can’t go back to the old methods and manual calculations. The drilling today is far more accurate than what we could accomplish before,”引用汉森的机器控制解决方案的生产率。

Back then, there could be a difference of 30 to 40 centimetres in the depth of the holes, and that affects the blast result. With the 3D solution, everything is as plane as a house floor.”

谈话已经完成，现在是时候采取行动了。第一个孔进行钻孔，控制和批准。汉森（Hansen）以如此熟练的方式准备了每个洞，处理雷管和电线，看起来几乎是冷淡的，但毫无疑问 - 爆炸经理知道他在做什么。

The shell for cushioning and absorbing lateral impact are placed on top of the area to be blasted, then the siren alarm rings.

The blast sounds dampened and controlled — WHOOOOMP!

And the rays of autumn sunshine continue glittering across the blasted earth.
