使用3D钻机解决方案在挪威钻探

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 ASis drilling the bedrock for ground preparations to build a fenced construction site, where they together with another company, Norsk Fjellsprenger, can store equipment and explosives. The team carries out the drilling work with 3D machine control solution from Leica Geosystems.


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是工作ing with drill rigs for eight years, beginning at the company E. Rolstad AS and now at Fjellsprenger AS. Before that, he worked as an excavator operator.

His machine is a Sandvik Ranger DX800 top hammer drilling rig. It weighs 15 tonnes and stands stable on its track, powered by a strong 225 HP motor from Caterpillar. Frydenlund can drill holes with a diameter of 76 to 127 millimetres with this machine. The drill rig is equipped with aLeica IRD3machine control solution for drilling applications, which helps Frydenlund to do the job quickly and with absolute accuracy.

Frydenlund 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(Frydenlund)经常在他的钻机钻机上更改工作网站。Fjellsprenger和许多不同的建筑项目合同,弗莱登伦德(Frydenlund)以及该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.

Comparing with his previous job site, it is easier here on the plane field in Vikersund.

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,”saysFrydenlund. “It gives me total freedom in my work. If I receive an offset height, I can build my drill pattern in the display. It is so easy! Then, I can do the drilling myself accurately. Every hole is drilled to specification with the right depth and angle. I don’t need a surveyor, everything is fast, and the as-built documentation is easy to export from the system afterwards.”

Frydenlund 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。

“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。


Meet the blast manager

Magnus Hansen, blast manager at Fjellsprenger

Fjellsprenger的爆炸经理AS Magnus Hansen住在钻探正在进行的建筑工地附近。如果他的手臂有足够的力量,他足够近的足够靠近的是从爆炸中拿出一块碎片的岩石,然后将其扔到他的房子里。

Hansen is the outdoor type. He is interested in hunting and fishing.

Hansen obtained the license for rock blasting – a 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:

  • 安全
  • planning
  • environmental concerns
  • considerations for the surrounding areas
  • closing of traffic.

“自从我们开始与Leica Geosystem合作以来,我们的生产率和质量提高了,并且由于机器控制解决方案可用,”汉森解释说。“We do not need surveyors on-site to the same degree as before, and that saves us time and costs. Frydenlundcan handle everything himself with the drill rig and work totally independently.”

“一旦尝试了解决方案,就无法回到旧方法和手动计算。今天的钻探比我们以前能做的要准确得多,”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。”

The talking is done now, and it is time for action. The first holes are drilled, controlled and approved. Hansen prepares every hole, handles detonators and wires in such a skilled manner that it looks almost nonchalant, but make no mistake ⁠— the blast manager knows what he is doing.

用于缓冲和吸收侧向冲击的外壳放在要爆炸的区域的顶部,然后是警报器戒指。

爆炸像是ds dampened and controlled — WHOOOOMP!

秋季阳光的光线继续闪闪发光。
