One of the most frequently used pieces of equipment in geologists is the backpack core sampling rig, which is known for its small size and excellent portability, and although its structure is simple, it plays a lot of roles in geological work.
Generally speaking, this kind of backpack-type core sampling drilling rig is mainly used in prospecting and prospecting, and I need to take this kind of drilling rig to participate in different geological projects almost every year in my more than ten years, some of which are for geology students to teach the use of equipment, and some of the work is to follow the geological team to do geological mapping or prospecting.
In addition, this equipment will also be used in engineering survey, transportation, power and other directions, of course, these will not be talked about today, which day a separate article to share. Today, I would like to share some of the application cases of backpack core sampling drilling rigs in the geological field that I have participated in.
1. Geology students practice field sampling.
This is a job that I am more impressed, when a teacher of geology at a university took students to the field to carry out the collection of outcrop samples, the original plan was to use the geological hammer to sample, but after arriving in the field, I found that the actual situation was not as easy as imagined, coupled with many students are not good at manual labor and hot weather, resulting in very slow sampling progress, and even unable to take out samples. Therefore, the teacher gave Deyan Technology a ** when he returned to his residence, hoping that a professional driller master would come to support him with equipment. Therefore, our group was sent to Luoning, Henan Province to participate in this teaching practice.
At that time, the temperature in the field was nearly 40, and the places we went to were low bushes, basically no shaded places, and the rocks were indeed very solid on site, but fortunately, we carried a backpack-type core sampling drilling rig and collected enough samples according to the teacher's requirements, and directly in the field to the students involved in this project for a real sense of equipment operation training, of course, the process is not much here.
2. Plateau geological research.
This was a project a long time ago, when I joined the team to participate in this expedition shortly after I came to work, and our task was to drill and hand over the collected core samples to the experts. Of course, it took a lot of effort to get to the sampling site, which is basically a shale mountain, where the slope is relatively large, and it is difficult for large drilling rigs to deploy, and the backpack-style core sampling drilling rig is suitable for this environment.
At that time, we took samples at many points, and even took samples above the snow line. Although the diameter of the sample is not thick, it is still time-consuming and laborious to use a large drilling rig to sample and build a platform in this kind of place, and the inherent advantages of portable drilling rigs can also be reflected at this time.
3. Replace the groove with drilling in the field.
Trenching should be clear what is dry geology, trenching as a means of investigation certainly has its straightforward benefits, but trenching on the environment is still there, especially now the country's attention to environmental protection, so trenching is slowly being replaced, and drilling instead of groove is to replace trenching in the form of drilling rigs.
Of course, the drilling rig can be a large drilling rig or a backpack drill, the advantages of the large drilling rig are obvious, the depth of the drilling, the sampling is coarse, but the disadvantages are also obvious, the volume is large, the transportation is difficult, the construction is time-consuming, the transition is difficult, etc. In general geological exploration, as long as the drilling depth does not need to be too deep, we will bring a backpack core sampling drilling rig and use it anytime and anywhere.
I think that although the backpack core sampling rig may not be a very high-performance equipment, it is like a miracle in the field, because you have no choice, unless you have the time and money to hire a large number of people to carry hundreds of kilograms of large drilling rigs back and forth.
