Long Hole , also spelled Longhole , is a limestone cave on the south coast of the Gower Peninsula between Paviland and Port Eynon . It is relatively small, measuring about 15 m (49 ft) deep after several excavations. It was first excavated in 1861 by Colonel E. R. Wood. Wood found evidence of a lithic assemblage and faunal remains. The faunal remains included cave hyena , reindeer , Woolly rhinoceros , mammoth , straight-tusked elephant and wild horse. [1]

A second excavation was conducted in 1969 by J. B. Campbell. Analysis of the evidence from the two excavations, including sediment and pollen as well as the lithic evidence, has identified Long Hole as an Aurignacian site contemporary with and related to the site at Paviland , evidence of the first modern humans in Britain.

The Long Hole

Jeong Yeoreum
2021

A detective is led by an accidental postcard to investigate an incident at the USFK (United States Forces Korea) base Camp Long. Camp Long is in ruins and has had no visitors in twenty years. In the process of gathering, defragmenting, and arranging neglected information, the detective discovers that a strange geographic data value called Camp Long ATM occupies all space and time. However, there are no traces of any ATMs or banks at the scene, only bright red bloodstains disguised as evidence. The film is a mystery report of a detective trying to understand the legacy of time.
The Long Hole is one of five films presented by the 19th edition of the Experimental Film and Video Festival in Seoul – EXiS, as part of a special selection on e-flux Video & Film streaming for two weeks from August 18 to September 1, and accompanied by a conversation between EXiS 2022 programmer Inhan Cho and e-flux’s Lukas Brasiskis. See the full program here .
The program is part of the series Festival Forum on e-flux Video & Film, presenting collaborations with established and emerging moving-image festivals from around the world.

Jeong Yeoreum reframes stories about the correlation between space and memory into visual language. Her work is a continuous process of fixated reinvestigation on a narrative, analyzing its mechanisms and dismantling the body from the parts.

The oil well is created by drilling a long hole into the earth with an oil rig.

The application-liquid release section (17) comprises a long hole , a long groove, or a projection-like body.

· In-mine horizontal boreholes: This technology involves drilling short – or long - hole boreholes horizontally into the seam prior to mining.

And he had me look through the long hole in the instrument’s box, the sound box, as he called it.

Fin collars (4) for maintaining the intervals between the plate fins (1) are provided on the rim of the long holes (3).

On a “ long hole ” (par 5) on my second shot the ball came to a stop fifteen inches (40 cm.) from the cup.

So in these long holes are we seeing that one end of the hole is one torpedo impact and the other end another?

More of the long holes with the razor straight top edges are found on both sides of the ship, both fore and aft.

A long hole (23d) is formed in the upper wall (23a), and a rotation connection target portion (23e) is formed on the side wall (23b).

Also there is a long hole , it is believed that when lord Ram lived here this hole was used to keep a watch on invaders.

However, this problem can be solved in polynomial time for certain graph families, such as asteroidal-triple-free graphs or graphs with no long holes .

However, new and innovative technologies such as long - hole in-mine directional drilling and horizontal wells drilled from the surface may offer more effective drainage in some cases

The sieving device (1) is provided with a first sieving section (first sieve (30a), second sieve (30b)) having sieves in which multiple long holes or slits are formed.

However, new and innovative technologies such as long - hole in-mine directional drilling and horizontal wells drilled from the surface may offer more effective drainage in some cases.

Rows of long holes in the steel sections and connectors allow continuous withdrawal of concentrated compound elements . In addition , PERI VARIO GT 24 flattens clamp elements and equating any assembly inaccuracies .

A secondary lever (22) comprises an insertion connection portion (22b) which extends downward from a longitudinal end thereof and is assembled with the long hole (23d) by being inserted therein from above.

Moreover, the DB plate fins (3) and the FB plate fins (4) are combined and arranged, and the refrigerant tubes (2) are passed through and fixed to the long holes and the half long holes .

The second long hole does not pull the release cable when the output lever rotates from the initial position in the first direction, and pulls the release cable when the same rotates in the second direction.

On the outer circumference section of the reinforcing member, a plurality of long guide holes are formed.

He felt as though he had been stripped raw and tumbled down a long black hole .

Long Hole Drilling

Perseverance Drilling, Underground Pty Ltd has a range of Top Hammer rigs as shown in the Equipment List . These rigs can be utilised for production drilling, drilling long hole rises, sludge and probe drilling, drilling cable bolt holes as well as drilling with drilling foams and mud in bad / broken ground conditions.
With a range of long hole rigs in the fleet and a philosophy to always have a rig up our sleeve, there is normally a machine available to fill a client’s requirements. With a flexible workforce including a management team that all drill if required we are in a good position to move quickly if required.
Our Top hammer rigs drill holes from 51mm using a R32 drill string up to an 89mm hole using a T51 drill string, including everything in between. This allows us to complete work from thin vein mines to bulk mining operations. All of our rigs are capable of drilling both up holes and down holes and our operators are competent in both. All rigs have capabilities to drill on an air-water mist as well as drilling using drilling foams and muds.
We have extensive experience drilling in thin vein ore bodies, and have techniques, particular procedures and specific drilling consumables for thin vein drilling to achieve the accuracy required to drill out thin vein stopes. We have specific procedures for differing length holes which include techniques and consumables. We have developed our own guide system which has also improved accuracy.
We use our fleet of Simba H157’s to complete production drilling in thin vein orebodies. We have a range of rails that are available to suit some of the smallest drives. The Simba H157 is ideal for these situations as the rail without a carousel can be set up, very close to the hanging wall, which is especially important if you have developed the drives with a Shanti profile. You can see some examples of this in the Gallery .
We also have two systems that we can use to align the rail, our own Laser Clino for dumped holes, or a laser stick system if there is no dump on the holes. Both increase the accuracy over electronic systems as they ultimately rely on measuring the orientation of the actual guide tube, rather than the angle of the rail holder. In one particular case the client later told us that our drilling had produced half the tonnes at twice the grade than what they had budgeted on.
We also have a lot of experience in drilling in bulk mining situations. Again we have started to introduce the guide system that we have produced and are getting better accuracy results. For drilling in the larger bulk mining stopes, we can drill 64mm holes with a T38 drill string, 76mm holes with a T45 drill string or 89mm holes with a T51 string.
Whether part of a production drilling program, or sometimes as a single job, we are often required to drill Long Hole Rises. These can be slot rises or ventilation rises. In most situations we drill the blast holes as well as the reamers, however we have also been brought in to drill around existing raise drills to strip them out for a larger ventilation rise. When these raise drills exceed the optimum drill length of a long hole rig, we will drill them top and bottom. The up holes at the bottom of the rise will be fired, then the down holes around the top of the rise will be fired.
We have developed equipment and techniques using drilling foams and muds to drill in extremely broken ground. In the worst cases we may also resort to using cement grouts or gypsum. All of our rigs can be fitted with systems to use foams and mud. We have used these techniques for production drilling as well as drilling holes for cable bolts in broken ground. The technique uses the cuttings to form a crust around the circumference of the hole. With less fines removed from the surrounding rock and a crust formed, we have been able to make the holes in broken ground stand up until they are used.
When we have rigs on sites we often complete a number of tasks, rather than just Production drilling. These other jobs include drilling cable bolt holes and drilling service and probe holes. We have been required to do a lot of sludge drilling in the past, to a range of procedures, depending on the geologists requirements. From drilling holes and recording ore encountered in Nickel that will later have a probe used, to high level capture of all cuttings then sample splitting and chip sampling in Gold. We can tailor our procedure to suit a clients requirements.
