The disciplines of surveying and mining both date back to ancient times. The ancient Greeks not only developed the science of geometry, but they also developed the first surveying tool: the diopter, an astronomical and surveying instrument dating from the third century BCE. The diopter can be regarded as th…
Image acquisition is the process of capturing analog images and converting them into digital form so that further processing can be done. (Rijwan Khan et al., 2022) It is the first task of the vision system, followed by image analysis. (Rijwan Khan et al., 2022) The process of image acquisition involves three steps: reflecting light from the area of interest, focusing the digital camera on the ...
In this post we share the most commonly used sampling methods in statistics, including the benefits and drawbacks of the various methods. Probability Sampling Methods. The first class of sampling methods is known as probability sampling methods because every member in a population has an equal probability of being selected to be in the sample.
Unlike the traditional geophysical methods (electric resistivity survey, seismic survey, etc.), GPR survey allows extremely high resolution along the trace and in depth, highly-detailed surveys, along with possibility to obtain information about the structure of the studied section and visualization of results during the measurement.

Technological advances have enabled the use of more sophisticated methods for mining surveying. These include satellite imagery, aerial LiDAR (Light Detection and Ranging), …
Mine surveys can efficiently produce results that save time, money, and man power. For example, calculating stockpiles by hand is very labor intensive with lots of potential for error. Modern …
Mine surveyors are responsible for accurately measuring and recording mine workings. They are essential to the design, planning, and safety of the surface and underground mining operations, which must be appropriately reflected on mine plans.
Surveying and mapping are indispensable in mining as geospatial and subsurface data constitute the foundation of any mining project. Miners rely on surveys and mapping throughout the mine …
Types of Data Collection Methods 1. Surveys and Questionnaires. Definition: Surveys and questionnaires involve asking a set of questions to a target audience, either in person, by mail, online, or over the phone. Types: Surveys can be structured (fixed response options) or unstructured (open-ended responses).
Acoustic scanner data indicate the breakout at the depth 283.2-283.9 m (a) along N110° and caving of clay at the depth 284.37-285.55 m of the Barren Measures from Adriyala borehole 1199.

Let's take a look at some of the specific strategies you can use to carry out exploratory research using primary research methods. Focus groups A focus group most commonly contains 8 to 12 people fitting the description of the target sample group and asks them specific questions on the issues and subjects being researched.
Some common types include: 1. Surveys and Questionnaires. Advantages: Online surveys and questionnaires let you reach a large number of people relatively easily. With large sample sizes, outliers are less prominent, making data more accurate and better for your analysis process. Individual surveys are cost-effective thanks to minimal marginal ...
This chapter offers an introduction to corpus linguistics as a methodology for studying language, literature, and other fields in the humanities.
Surveying instruments are used to assist in measuring land, including vertical distance, horizontal distance, and volume of excavated material. A land surveyor uses surveying instruments to make precise measurements of the earth's …
Here, the image registered by the method under investigation is compared (by a proper metric in the image space) with the same image registered by another comparative method. As the comparative method we use preferably 'gold standard method', which is a method commonly believed to be the best in the particular application area or for the ...
Although traditional techniques are still in use in some places, this method has been replaced or accompanied by modern solutions such as aerial mapping and remote sensing. Despite this, the traditional method is still essential for some mining companies and resource management. It gives a detailed, up-close view of the subsurface geology.
Electromagnetic (EM) methods were developed in the 1920s and initially deployed for mineral exploration (de Beer 2011).Recent reviews that discuss EM methods as applied to mineral exploration include Sheard et al. (), Zhdanov and Vallée et al. ().These papers concentrated on the early part of the period 2000–2010, so this review will concentrate on the …
