Traditional exploration workflows—drill core sampling, lab assaying, and multi-day result turnarounds—struggle to scale when daily drilling costs run $15,000–$25,000 in equipment, fuel, and crew, and when waiting for lab results creates costly delays. Portable XRF analyzers alter exploration economics by moving chemical ...
A comprehensive discussion of the technical aspects of the Cone Penetration Test method and the principles and methods for interpreting these soundings. This monograph includes a range of interpretation methods that allow for the estimation of a number of basic geotechnical ...
When contractors think of truck-mounted soil sampling rigs, they often picture large models mounted on heavy-duty trucks that have difficulty getting into hard-to-access areas. However, Lone Star Drills offers the option to mount some rigs on light- to medium-duty trucks that offer quick setup and more versatility than large truck-mounted drills. ...
Soil sampling often requires drills that can get into delicate and remote locations, whether that’s a back yard, wooded property or rural, rocky area. Our soil sampling rigs offer a variety of transportation options for accessing these challenging jobsites, ranging from trailer-mounted units light enough to pull with an ATV or UTV, to rigs ...
The few minutes it takes to go through daily maintenance is simple but significant to prolong the life of your drilling equipment. It’s important to know what to grease and how often — this minimizes the risk of equipment malfunction. Whether sampling soil or drilling water wells, the following guidelines to regular greasing and ...
Whether it’s choosing the location for a new home or rotating crops that feed an entire country, soil sampling data is used to make important, long-lasting decisions. Recording soil sampling data accurately and properly handling the collected samples can save time, reduce cost and streamline ...
Whether you’re drinking tap water or well water, its quality needs to be monitored regularly. With tap water, the city or local government regularly tests for contaminants like petroleum, heavy metals and other pollutants. However, private water well testing is left up to the ...
Portable soil sampling equipment is gaining traction. Soil sampling contractors will often supplement their fleet of large truck-mounted or tracked drills with compact units that are far gentler to turf and can work in confined spaces. For others who want the convenience of owning soil sampling equipment, such as site prep or ...
Soil sampling is a crucial first step in everything from construction to farming. It provides information about the chemical and physical condition of the soil. Often, the purpose is to test for contamination, nutrients or soil strength to gauge the success of a project. The resulting information helps optimize plant growth, solve soil-related problems or determine the extent of soil ...
Soil Testing and Analysis Geotechnical Investigation Conduct a geotechnical investigation to gather detailed information about the soil properties at the construction site. This involves: Soil Sampling: Collecting soil samples from various depths using drilling rigs. Laboratory Testing: Analyzing the soil samples in a laboratory ...
A bore log refers to a record detailing the in-situ conditions and aspects of geotechnical exploration activities such as drilling boreholes and mining. The log information needed to create a bore log is obtained through visual inspection of samples obtained from the geotechnical process. ...
This approach outlines how materials are described, design of the logs, information types to be collected, applied symbols and terms, and observed standards. During the logging of soil samples, elements considered include classification, naming and description of soils. Descriptions for rocks include rock types and weathering properties. Drilling data collected ...
Now that solar energy has a larger share in our energy supply, it is becoming more important that solar panels are reliable and behave predictable. To be able to predict when solar panels will fail, insight into the failure mechanism is essential. This knowledge is used to improve the quality and longevity. Scientists at TNO Energy Transition and Solliance Solar Research have developed a ...
Our family specialised in reverse circulation drilling which produces rock samples to analyse for mineral deposits. ...
Since the 1990s, however, reverse circulation drilling has been the process of choice for obtaining rock samples in soft to medium consolidated formations. The benefits of reverse circulation drilling are well documented. Samples are protected from cross-contamination since they are pulled up in sequence as the reverse ...
Investigations have been on-going since 2008, including geophysical investigations, outcrop mapping, sampling of drill cuttings, and diamond core drilling. The mineralization is not defined at depth and/or in strike extension. ...
Acids and alkalis used in mining are recorded by the Mine Safety and Health Administration (MSHA) as including wet cement, wet grout, shotcrete, lime-cement dust, trona and rock dust. Exploration drilling Due to its ability to dissolve most oxides and silicates, hydrofluoric acid is used in the analysis of core samples taken during exploration ...
The ability to sample vapor below a building and perform similar tests inside the building and compare the two test sets has become easier with present sampling techniques. The sampling involves drilling into the building foundation to reach the underlying soil. A sealed probe is placed in the opening and attached to a vacuum ...
This can occur in the open air or into buildings, offices, factories, warehouses, vacant, or abandoned. Vapor intrusion testing/sampling is a method of determining if known or suspected ground contamination is a result in these chemical vapors escaping into the building and are they of such concentration that they can cause short term or long term health effects. ...
Creating a Borehole Database A series of exploration boreholes were drilled. Samples were taken every five feet and sieved in order to determine the relative percentages of sand, gravel and clay (or other non-sand/gravel material). These samples were restricted to the interval below the base of the soil profile and the top of the bedrock. ...
