In mineral resource exploration activities, the drilling machine required is also called a drilling machine. It is a kind of mechanical equipment that drives drilling tools to drill underground and obtain physical geological data. The main function is to drive the drilling tool to crush the rock at the bottom of the hole, which is used to drill cores, cores, cuttings, gaseous samples, liquid samples, etc., to find out the underground geology and mineral resources.

The rig that the boss had rented from Mount Issa was a big guy in the real sense that it looked like a crane in the light of things. When it has not entered the working state, the drill mast more than ten meters long is flat on the car body like the boom of the crane, and the front of the car is more than one meter long. However, once in working condition, the mast is erected high at the tail of the car body, providing strong power for the drill pipe to drive deep into the underground rock formation.

This drilling rig is a fully hydraulic multi-functional truck-mounted drilling rig from BAUER. As the world's most professional drilling rig manufacturer, Baumer has a high reputation for many of its drilling rigs around the world. The RB-50 is a vehicle-mounted deep drilling rig manufactured by Parkla, a subsidiary of the BAUER Group, and can drill to depths of 1,200 to 1,500 meters below the surface.

Because this drilling operation requires five holes, the leader will choose this vehicle-mounted drilling rig, after all, the mobility of the vehicle-mounted drilling rig is much higher than that of those tracked drilling rigs.

The Pacla drill rig has a very good rate of penetration of up to seven meters per hour, which of course refers to the rate of penetration in the rock layer, which is another reason why the head chose this rig.

This big guy has driven to the designated position at this time, at this time in the roar of the engine, the drill mast up to more than ten meters is slowly erected, once the drill mast is completely erected, then it means that the drilling operation has begun.

Drilling is not a trivial job, not only does it take a long time, but the staff also has to pay attention to the drilling of the drill pipe at any time to prevent the drill pipe from breaking downhole, and at the same time, it is necessary to continuously take the core through the rope to determine the geological conditions of the underground rock formation.

Drilling is the most important part of the survey, so there is a lot of work that needs to be done, and just building a database is a very tedious job.

To establish a solid mineral borehole database, it is necessary to fill in a large number of data, such as the basic information database of mining area, the dictionary database of mining area, the basic information database of boreholes, the bending measurement database, the hole depth correction database, the geological record database, the basic chemical analysis database, the phase analysis database, the specimen sampling database and so on.

Only when these databases are fully established, can we finally obtain detailed data of this borehole through data comparison and analysis, and judge the specific situation of underground minerals based on this.

If the burial depth of solid minerals is relatively large, then it will take several days or even more than ten days to drill an eye, but Tang Feng's mine does not have this possibility, because as early as the condensation of this vein, Tang Feng considered open-pit mining, so the burial depth of this vein is very shallow, so that the drilling operation that began at nine o'clock in the morning, and at one o'clock in the afternoon, the staff broke out in surprise.

"Boss, boss, judging from the extracted core samples, there is a silver deposit about twenty meters below the ground, and the specific data is being analyzed, but this is obviously very good news!" Tang Feng and the head were sitting in the board room drinking coffee, Johnny pushed the door open, ran in and shouted loudly.

Leader Huo stood up immediately, and asked with an excited look on his face, "What is the specific situation?" ”

Johnny steadied himself and said, "Boss, when the first hole was drilled to a depth of twenty meters today, we extracted the core with a rope according to the regulations, and silver ore was found in it, and in terms of fineness, the silver ore below this drilling site is of high grade. Cross has taken the core away for assays, and it won't take long to get the exact data, and now that drilling is continuing downward, we'll have to see how deep this silver vein is! ”

The leader was so excited that he smashed his palm with his fist, and said to Tang Feng with a smile: "Tang, this is good news, let's go to the operation site to have a look?" ”

Tang Feng naturally would not refuse, and the three of them happily came to the location of the drilling rig's operation. At this time, all the employees of the explorer company were already gathered around the drilling machine, and everyone had a happy smile on their faces. After all, this first drill can drill out the minerals, which is definitely a very good start.

Although the driver of the drilling rig is not an employee of Explorer, he is very happy that he can drill precious metals from the first drill, and according to the driver's experience, if nothing else, there is almost certainly a precious metal mine under this land.

The big guy waited for more than two hours, and the drilling depth had reached 30 meters, at which point the drilling rig stopped drilling, pulled the drill pipe up, and used a rope to extract the core in it, which made everyone excited.

The nearly three-meter core is full of silver ore, which means that if there is a silver mine underneath, then the recoverable thickness of this silver ore is almost three meters! You must know that the recoverable thickness of the general silver mining industry is mostly about 0.8 meters to 1 meter, which is already a very good silver vein, and the recoverable thickness here has reached three meters, you can imagine how rich the silver contained in this vein!

The excitement here isn't over yet, and even better news comes with the arrival of inspector Cross.

"Hey, boss, if it weren't for the fact that our equipment is the most advanced testing equipment, I wonder if there is something wrong with our equipment! God forbid, sir, we've found a big guy this time! Cross said with irrepressible excitement as he handed the form to the head.

Tang Feng came over and looked at the form with the leader, and it didn't take long for the leader to say excitedly: "Guys, our work is not in vain, this time we did find a big guy!" Based on the core collected, assays have indicated that the vein is likely to be an extremely rare silver-gold-platinum composite vein. The average grade of silver is up to 880 g/t, and the average grade of gold and platinum group metals is also 83 g/t. Guys, it's a miracle! ”

A group of people suddenly let out a huge cheer, and Tang Feng was naturally no exception. The assay data from the core is a little higher than the average grade of the entire silver mine, but this is no longer a matter of fact, after all, it is impossible to drill only this one hole, and many holes need to be drilled to determine the specific extent of the vein and the thickness of the mine, so as to calculate the reserves of the vein!
