Drilling in Norway with 3D Rig Solution

作者：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

A firm handshake from a weathered hand, an impressive moustache, and on top a hard hat with a miner headlamp – driller operator Odd Are Frydenlund is presenting himself.

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 iRD3machine control solution for drilling applications, which helps Frydenlund to do the job quickly and with absolute accuracy.

弗莱登伦德is a fan of Liverpool FC, he likes motorsport and in his garage stands one of his treasures: a seductive maroon Chevrolet Corvette from 1981.

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.

Just a few weeks earlier, Frydenlund was balancing his rig on the edge of a 30 m tall cliff in a quarry in Maura, Norway. For safety reasons, it was very important to be able to operate the machine remotely from outside of the cabin and additionally anchor the machine into the supporting soils.

与他以前的工作网站相比，在维克森德的平面场上更容易。

For some operators, who worked for a long time in the construction industry, inventions like GNSS-assisted machine control might be scary for the first time, but Frydenlund is on the contrary.

“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。”

弗莱登伦德quickly learnt how to operate the drill rig with the new 3D machine control system.

“I have not experienced difficulties with learning the system, and if I had, I would have preferred to call them challenges instead,”reflecting Frydenlund on his learning experience. “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!”

Frydenlund反思了他与Leica Geosystems Rig Solutions产品经理Petter Heyerdahl建立了良好的关系，以及他在Leica Geosystems的个性化支持团队中的经验。

“I am sitting here in my drill rig 40 hours a week – it makes you think and you get new ideas! I have discussed my ideas and wishes with Petter. He listened to me, and I got most of the features that I asked for,”弗莱登伦德解释说。

认识爆炸经理

Magnus Hansen, blast manager at Fjellsprenger

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。

汉森获得岩石爆破——的许可license that must be renewed every five years. He worked in the industry for 14 years. The tasks that a blast manager is responsible include the overall responsibility for the work on the site and comprise:

• safety
• planning
• environmental concerns
• considerations for the surrounding areas
• 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,”refers Hansen on the productivity of machine control solutions。

那时，孔深度可能有30至40厘米的差异，这会影响爆炸结果。使用3D解决方案，一切都像房屋地板一样像平面一样。”

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.

爆炸听起来受到抑制和控制 - whooocm！

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