Diamond Drilling has contributed and made revolutionary changes in the mining industry which have directly resulted in the discovery of many mineable ore particles that would otherwise be untapped. Before introducing the mainstream of drilling structure, application, and mechanism that is used in construction projects to penetrate or cut heavy rocks. Diamond drilling is a mechanism that is used by builders or contractors to remove solid cylinders of rocks (core blocks of rocks) from deep within the earth.
Diamond core drilling is a more accurate, faster, and economically efficient method of drilling rocks, heavy slabs or concrete structures. The drilling techniques don’t lead any vibration or damage to the surrounding structure. This technique is completely secured, smart, and noise-free which makes all cuts environment friendly for construction projects. This method is safe as well as effective to reinforce concrete and enable contractors to get holes of required diameters at expected locations and parts of rocks or concrete.
The term diamond core drilling comes with the “diamond bit” drill used during the concrete penetration process. The best and effective group of small, industrial graded diamond sets are used in the production of drill bits. Then this diamond bit is attached to the drill rod that helps to measure around 10 feet in length. More sections of the drill pipe can be attached to the top of the drill rod and allow greater depths to be drilled as required. Therefore, the number of rods attached to the top of the drill rod that determines the depth that can be drilled. Within the drill rod, a core tube is attached to the cable attached to the latching mechanism.
Rotary & Wire Line Diamond Drilling
There are two types of diamond drilling, that includes rotary drilling and wireline drilling process. If you talk about rotary drilling, it is used primarily for borehole drilling, rotary drilling is used to form a deep observation borehole and obtain a representative sample of rocks. This drilling method involves On the other side wireline drilling is used for solid core sampling. Wireline core drilling systems are used for drilling medium to ultra-deep boreholes, which offers the most efficient core sample extraction from the rock mass without pulling the entire drill string.
To extract the core, the drill rod rotates the diamond bit and spins it into the rocks, slabs, or ground. When The drill bits bore through the rock or concrete, solid rock is taken into the circular beginning at the end of the bit, into the core tube, and can then be recovered at the surface as it piles up. Once the core is recovered at the surface, it can break along natural fractures and stored in core trays to await analysis.
The drill bit must be well lubricated with the water in order to avoid overheating or sticking, it helps to keep the drill moving through the rock smoothly. The perfect drilling process helps drillers to evaluate subsurface conditions for optimum core extraction. To ensure that drilling remains effective and sufficient, the rotation speed and efficiency must be restricted and monitored.
Diamond core finds its primary function in the exploration mining industry. It is generally the last stage of exploration, during which the orebody is delineated in three dimensions. This will help determine whether the prospect is economically viable. A diamond drill rig is used to extract long vertical sections of core from deep in the ground which can be analyzed at the surface by contractors.
The core can then be analyzed using a wide range of petrologic, structural, and mineralogical techniques in order to determine the potential mining site is economically viable. Extracted cores are initially washed and macroscopic features are logged on by an exploration geologist. The core is then cut and representative samples are sent for chemical analysis.
Diamond stitch drilling is commonly used by contractors in order to create a series of neighboring holes in any pattern required. This drilling method is also used to prevent large sections of concrete slabs, walls, concrete blocks, or bricks keeping the structural integrity of associated areas intact. Whether it is related to crane base, making holes for life shafts, or creating openings for pile caps, diamond stitch drilling is the best technique for any complex drilling and cutting you must have. If you are preparing for removing the damaged or unwanted structure of any construction blocks, slabs, or creating wall opening channels for the insertion of utility pipes, diamond drills are the best techniques and alternatives.
Regardless of the hardness or depth of concrete, the diamond drilling method can be efficient or effective to cut the wall, slab, concrete through any piece of construction material leaving the sharp edge and smooth ground surface behind. The application and process of diamond drilling involve a site survey, construction process, diamond blade or bit selection, advance planning, and safety management.
