使用3D钻机解决方案在挪威钻探

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 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.

Meeting the drill operator

弗莱登伦德（Frydenlund）在露面，是一只风化的手，令人印象深刻的胡须，令人印象深刻的胡须，顶部带有矿工大灯的硬帽子 - 钻机操作员奇异的握手。

弗莱登伦德is working 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.

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，他的珍宝之一：1981年起诱人的栗色雪佛兰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，弗莱登德（Frydenlund）在挪威莫拉（Maura）的一个采石场（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。

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

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会首次令人恐惧，但弗莱登伦德（Frydenlund）相反。

“I have experience with Leica Geosystems’ equipment already from my previous job,”says弗莱登伦德。“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，如果有的话，我宁愿称他们为挑战。”反映弗莱登伦德的学习经历。“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!”

Frydenlund反映良好的关系他哈s developed to Petter Heyerdahl, product manager for rig solutions at Leica Geosystems and his experience with Leica Geosystems’ personalised support team.

“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

Fjellsprenger的爆炸经理Magnus Hansen

Fjellsprenger的爆炸经理AS Magnus Hansen居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，就足够靠近他从爆炸中拿出一块零散的岩石，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:

• safety
• 规划
• 环境问题
• 周围地区的考虑
• 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。

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.”

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.

用于缓冲和吸收横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。

The blast sounds dampened and controlled — WHOOOOMP!

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