ASTM's geotechnical engineering standards are instrumental in specifying, testing, and investigating the physical/mechanical properties and characteristic behaviors of surface and subsurface earth materials that are relevant to a construction project.
Rotary drilling method of boring is useful in case of highly resistant strata. It is related to finding out the rock strata and also to access the quality of rocks from cracks, fissures and joints. It can conveniently be used in sands and silts also. Here, the bore holes are advanced in depth by rotary percussion method which is similar to wash boring technique. A heavy string of the drill rod ...
Drilling Methods Used in Coal Mines Posted by: Jess Peláez in Drilling, Drilling and Drill Results For coal deposits, like most other minerals, drilling is a key to identifying in detail the grade and size of the resource, both prior to mine development, and during operations.
Well drilling methods are numerous and only the basic principles and applicability of selected and conventional methods are presented. A brief Description of Drilling Methods is presented below. Drilling methods can be grouped into two general categories:
JED Drilling is a drilling company that provides geotechnical drilling services to a wide variety of clients. Both auger drilling and direct push drilling are used to drill for geotechnical and civil engineering purposes.
The need for core sampling in geotechnical projects In most geotechnical and environmental drilling, augers are used to drill in the majority of projects. However, the need still arises to perform core sampling for certain geotechnical projects, usually when the presence of bedrock needs to be confirmed.
Environmental projects involve the specialized applications of geotechnical drilling methods to monitor the quality of sub-surface material and assist in the control and remediation of …
Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions.
Geotechnical Drilling and sampling of soils and bedrock provides information about the formation and stability characteristics vital to the construction industry. By studying these characteristics along with ground water and bedrock mapping it allows the process of construction to be carried out in the best manner with no surprises. A 2′ split spoon is the most effective method of retrieving ...
The Proper Equipment Makes A Difference. There are various types of geotechnical drilling, each requiring specific methods. GES maintains state-of-the-art equipment necessary for all types of geotechnical drilling, large jobs and small.
Geotechnical Investigations & Testing Methods What are Geotechnical Investigations? Geotechnical investigations are performed to obtain data on physical characteristics of soil/rock around a site to design earthworks & proposed structures, or to support the repair of distressed earthworks/structures caused by subsurface issues.
For drilling programs where more traditional methods of core orientation are undertaken, the orientation of individual discontinuities and geological structures can be calculated by measuring the alpha (α ) and beta (β) angles of the discontinuity and the orientation of the drillhole at the location of the discontinuity, as determined by a downhole survey data for the core hole.
Our drilling equipment is available for both onshore and offshore projects and is capable of drilling in any terrain or location. MATECO Drilling is known for our ability to complete projects both large and complex without sacing performance and providing quality samples.
