An inherent problem with using drill cuttings as a stemming material is non-uniformity in terms of particle size and compaction. This sometimes leads to blowouts from the ... and damage structures and equipment. Another prime blasting consideration, in addition to the type of stemming material, is the length (depth) of stemming material. A ...

Drilling-fluid waste, drill cuttings, waste generated by cementing or completion operations, and waste water from the rig must be handled and stored separately. Another option is minimizing the initial volume of cuttings through installation and careful maintenance of high performance solids-control equipment.

Screw Conveyors ( Augers ) are commonly used to move drilled cuttings and associated fluid. They can be arranged to collect the cuttings (usually relatively dry oil-based cuttings) from the individual pieces of solids control equipment and convey them to another area of the drilling rig where they are used to load cuttings boxes (skips). The …

The results showed that compared with no drill cuttings stemming, the amount of explosives was reduced by 6.1–9.7% when drill cuttings stemming was used. Furthermore, the use of drill cuttings can also improve the working environment; for example, rock dust was reduced by 23.1–28.7%, and harmful gases were reduced by …

In order to increase the efficiency of explosive comminution, the borehole pressure must be maximized and pressure losses minimized. The majority of these pressure losses occur from premature borehole venting and through weak layers intersecting the borehole. With the use of proper stemming material and amount of stemming these pressure losses …

Using drill cuttings is a choice of quantity over quality. It is highly unlikely that you will ever get a perfect representative sample, but drill cuttings provide you with an abundance of representation and availability. A good analogy for drill cuttings is to think of a road map and imagine what the world was like before Google Maps.

The Stemming of blasthole collars in surface mines with an inert material redirects blasting energy to the rock more efficiently. The stemming length is a function of many variables, such as stemming material, plug, explosive, etc. Excessive stemming causes increase in stiffness accompanied by excessive confinement and resulting in the …

Among the byproducts of drilling are what we call "drill cuttings"—tiny f fragments of rock or soil churned up by the drill bit as it penetrates the earth's surface. Understanding the nature of these cuttings and managing them effectively is crucial for both the drilling industry and environmental conservation efforts.
