What does geological prospecting mean?
Question 2: What is geological prospecting? What's the purpose? There are two points in the geological survey report:
First look at the geological history, including topography, geological structure, stratigraphic distribution, geological structure and so on.
The second is to look at the geological stress, mainly the physical properties of the stratum.
The third is to look at the degree of geological deformation and stratum deformation.
These three are closely related. Finally, for the safety of buildings, safety is mainly considered from two aspects: stress and deformation.
Question 3: What does geological exploration mean? It means that industrial deposits are found in the mineral survey. In order to find out the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and provide the mineral reserves and geological data needed for mine construction and design, it is necessary to investigate and study the geological conditions such as rocks, strata, structures, minerals, hydrology and landforms in a certain area.
Question 4: What does real estate mean? At the beginning of design, the building needs to explore the geology and soil layer to understand the bearing capacity of geology and design the building structure.
Question 5: The difference between exploration and geological prospecting. No matter which school's similar major is this kind of "exploration", there is not much difference in fact. Differentially speaking, geological survey mainly refers to the study of engineering geological problems, such as industrial and civil building survey, highway survey and so on. Geological exploration refers to the study of geological engineering problems, such as geological disaster exploration and mineral exploration.
Question 6: What does this symbol mean in the geological survey report? Engineering geological investigation report is one of the basic data of engineering design and an important basis for design. As designers, we should correctly understand and use the survey report, instead of copying all the geotechnical parameters suggested by the survey unit. Some of them need to be judged before use, while others need to be analyzed and calculated before they can be used in engineering design. As a designer, it is a necessary prerequisite for foundation design to have a comprehensive understanding and mastery of soil (rock) layer structure, engineering properties and engineering problems arising therefrom.
Question 7: What is the basis of geological survey? Of course, besides surveying and mapping, there are many other geological works that need surveying and mapping assistance.
For example, field drilling and final hole measurement in prospecting and exploration stage; Some views on geological field mapping
Actual measurement of inspection points; Accurate measurement of some large structures in the field, etc. Surveying and mapping is very important for prospecting.
The purpose of this paper is to use the collected measurement data after accurately locating the mineralization point.
Data for three-dimensional comparative analysis, so as to roughly infer the occurrence of ore bodies (dip, dip, strike
Arrive and wait. ), which provides some basis for further exploration. If in mine production,
Measurement plays a more important role in geology. Daily measurement of working face and goaf
The measured data provide timely data for geological work and help geologists analyze the vacancy of ore bodies.
Interactive morphology, predicting ore body changes and guiding mining.
Surveying and geological exploration are inseparable! ! ! !
Question 8: What does the geological survey team mean? Mineral geological exploration refers to the exploration of mineral deposits with industrial value that can be developed and utilized in the near future through detailed investigation. According to relevant specifications, reserves at all levels should be explored, among which B+C reserves should account for a certain proportion, and geological exploration reports should be submitted as the basis for feasibility study and design of mine construction. Basic requirements: (1) Detailed geological and structural investigation of the exploration area; (2) The control and research accuracy of the shape, occurrence and spatial position, ore grade, structural structure, industrial type, grade type and its proportion of the ore body (layer) can meet the requirements of exploration corresponding reserve level and mine construction design; (3) Study the ore processing, mineral processing and metallurgical properties, and evaluate whether it can provide industrial architectural design; (4) Detailed exploration of hydrogeology, engineering geology and other mining technical conditions; ⑤ Detailed technical and economic evaluation of the deposit. The person in charge of this work is a geological prospector. Here are some tools used:
Question 9: What is the geological prospecting fee, and what expenses mainly include? engineering geological survey
Geological mapping, exploration, indoor experiment, in-situ test, etc. Study and evaluate the engineering geological conditions of the construction site. It provides necessary basis and parameters for the planning, design and construction of engineering construction. Engineering geological conditions usually refer to the topography, landform, geological structure, stratum lithology, unfavorable geological phenomena and hydrogeological conditions of the construction site.
Survey content
There are mainly the following five items:
(1) Collect and study the existing regional geology, topography, remote sensing photos, hydrology, meteorology, hydrogeology, earthquakes, engineering experience and existing investigation reports. ;
② Engineering geological survey and mapping;
③ For engineering geological exploration, see Engineering Geological Mapping and Exploration;
④ See geotechnical test and field prototype observation, rock mechanics test and test for geotechnical test and observation;
⑤ Data collation and compilation of engineering geological investigation report.
Engineering geological investigation is usually carried out step by step according to the engineering design stage. Different types of projects have different stages. For small and medium-sized projects with simple engineering geological conditions and certain engineering data, the investigation stage can also be merged appropriately.
Investigation methods and workload
It mainly depends on six aspects: project category and scale, investigation stage, complexity and research status of site engineering geology, engineering experience, building grade and its structural characteristics, and special requirements of foundation design and construction.
