Drilling in Norway with 3D Rig Solution

案例分析

作者:Arne Forsell

阳光的光线撞到了西部的树木繁茂的山坡。这条古老的道路似乎无限期地向上走。阴影很长。山区湖中的水在另一侧闪闪发光。世界上最高的滑雪跳跃坡度,距离树林高达200米的最陡点,可以在地平线上看到雪覆盖的山顶。我们在挪威的维克森德(Vikersund)距奥斯陆(Oslo)几个小时的车程,整个场景都以秋天的颜色发光。

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。


遇见演习操作员

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,现在是Fjellsprenger。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。它重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可以用这台机器的直径为76至127毫米的孔钻孔。钻机配备了Leica Ird3用于钻井应用的机器控制解决方案,这有助于Frydenlund以绝对的准确性快速地完成工作。

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.

Frydenlund经常在他的钻机钻机上更改工作网站。Fjellsprenger属于许多不同的建筑项目,弗莱登伦德(Frydenlund)以及公司的许多其他机器都在建筑工地之间移动。

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.

Working over the cliff with the remote support on the machine control solution.

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.

“我已经有了我以前的工作中的Leica Geosystems设备的经验,”弗莱登伦德。“这使我的工作完全自由。如果我收到偏移高度,可以在显示屏中构建钻头图案。太容易了!然后,我可以准确地进行钻探。每个孔都钻出以右深度和角度的规格。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. “您只需要有些好奇和感兴趣,然后就像您学会骑自行车一样 - 一旦学会了它,就不会忘记!”

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。

“我每周40个小时坐在这里的钻机中 - 这让您思考并获得新的想法!我已经与彼得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,”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.

汉森是户外类型。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:

  • 安全
  • 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,”在机器控制解决方案的生产率上引用汉森

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。”

谈话现在已经完成了,现在是时候采取行动了。第一个孔是经过钻,控制和批准的。汉森(Hansen)以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!

秋季阳光的光线继续闪闪发光。
