The number of paste backfill operations in the mining industry has been
increasing rapidly since the 1990’s. Paste fill operations, when designed and operated properly,supply an engineered, low strength structural fill material for underground backfill purposes. There is a great interest to apply paste technology for surface disposal of wastes in the base metal, gold mining and industrial minerals sectors.
The definition of paste is generally used very loosely in the mining industry. Paste is a densified uniform material of such mineralogical and size make up, that it will bleed only minor quantities of water when at rest, experience minimum segregation and can be moved in a pipeline at line velocities well below that of critical velocities for similar sized materials at lower pulp densities. Pastes can remain sitting in a pipeline for extended periods of time when no cementitious material is present, and its slump can be measured.
At 77 yards in length, St. Vincent Crescent Tunnel which lies just south of the 950 yard Kelvingrove Tunnel almost feels like an afterthought. However, despite the fact that it's seen a fair amount of backfill, the short tunnel still holds a few surprises. Two sewers run along the top of the tunnel and a pipe can be spotted, leading down into the infill.
Just beyond the tunnel, the abandoned railway comes to an abrupt end when the live line passes over at-grade. However, prior to recent flood prevention works, the Glasgow Central Railway passed under the line live before entering the 190 yard long Stobcross Depot Tunnel. This tunnel ends on the live line just west of the Exhibition Centre Station so even if I could have walked in, I probably wouldn't have.
Thanks to the aforementioned flood prevention works, you can walk all the way through Kelvingrove Tunnel but if you go back just over two years, this wasn't the case.
A portion of the cross-cut cavern has once again been backfilled to allow for access to excavate the top headers of the north and south platform caverns.
Simple tube beads with pattern backfilled. Some of these pattern were made using Kor Tools and other free-hand in a technique shown to me by Nikolina
MacArthur Ditch backfill construction is back underway. A rock plug was placed along the length ditch’s southern extent to strengthen the plug and prevent erosion during high velocity flow events
In December of 1994, the River Kelvin burst its banks and the flood waters rushed through the route of least resistance, which happened to be former tunnels of the Glasgow Central Railway. The flood waters tore through the Kelvingrove Tunnel and eventually made their way to the lower level of Glasgow's Central Station.
As a result, measures were taken to prevent this from happening again. These involved backfilling St. Vincent Crescent Tunnel but any excess water was still pooling at the southern end of Kelvingrove Tunnel. As such, this fresh layer of sloping ballast was recently laid. You can see the tops of the refuges just poking up from behind the infill which hopefully provides an idea of how significantly the tunnel has been in filled.
Interestingly, as the tunnel is only just below Kelvingrove Street at this point, a sewer can be seen passing through the top of the bore. Seeing sewers passing over Glasgow's tunnels is quite a common occurrence as they can also be spotted in the Great Western Road, Balgray and St. Vincent Crescent tunnels and no doubt a few more.

To go under or over the new sewer pipes.
Don't knew if they are intended for different parts of the job, or if they are just two kinds of relatively clean gravel that meet the job specifications.

Were all about green. There has not been one load of trash taken
away. Concrete, block, and non decomposing debris used for backfill !
A bulldozer enters the left side drift of the future north platform cavern to temporarily backfill a portion of tunnel.
Position your beads onto the glue. If you can gently backfill the bead holes with more glue to secure better.
Leave UPSIDE-DOWN to dry!!!
Looking north at construction of the MacArthur Ditch contract (B) and borrow site (A). The backfill continues northward into the Kissimmee River Restoration Project Phase I restoration area floodplain.
As fill is added to the trench around the new culvert under SR 532 near Stanwood, workers are continuously compacting it.
The new culvert will improve fish passage in Secret Creek. Right now salmon and steelhead in the creek have to first find and then swim through a 4-foot diameter pipe under the highway. The 18-foot wide and 10-foot tall wider will improve habitat for fish and other wildlife in the area.
Construction crews completed building the structure of the support for the future Evergreen Point Road lid as concrete workers prepare to pump concrete into it from the top.
polymer clay over a scrap clay armature.
backfilled, sanded and buffed.
trying to recreate the night sky. i used a metalic blue polymer clay and glitter.
unfortunately no matter how much glitter i added the effect wasn't nearly as strong as i wanted
Heavy equipment worked in concert to dig a trench and then install a drainage culvert near the SR 520 interchange at 84th Avenue Northeast.
Excavators, loaders, bulldozers and dump trucks worked throughout the day on July 14 to place soil over the newly installed fish-friendly culvert underneath all lanes of SR 520.
A collection of Late Neolithic Grooved Ware pottery that had been backfilled into a shallow pit, animal bone and worked flints were also recovered.

New farmer Leonardo Aguila shows U.S. Department of Agriculture (USDA) Natural Resources and Conservation Service (NRCS) Soil Conservationist Axel Sanchez the progress he has made with the underground outlet pipeline project on his 6.3-acre farm in Fallbrook, CA, on Nov. 11, 2018. Soon the soil they stand on will be backfilled over the black drainage pipe to protect and secure it in place.
Leonardo Aguila is extremely proud of his 6.3-acre farm in Fallbrook, Calif. The mature orchard of avocado trees, on its sunny hillside near San Diego, caught the eye of this Navy veteran three years ago, and he knew he had to buy it. Some of the trees showed signs of stress due to lack of irrigation from the high cost of water and regular drought - it just needed some tender loving care. Aguila knew he was the one to provide it.
Born in the Philippines, Aguila immigrated to Guam, a United States territory, as a young man and promptly enlisted into the U.S. Navy. He served in the military for 17 years and dedicated another 17 years as a civilian employee for the Department of the Navy. Once retired, he saw the avocado orchard and longed to live the life he remembered as a child, growing up near orchards of mango, coconut, and banana farming in the Philippines.
But in the Philippines, the island received plenty of rainfall to nourish plants. In California, farms need efficient irrigation to help the trees stay healthy. And, due to the orchard being on a steep hillside with erosion concerns, something had to be done to prevent the hillside from being washed away when it rained.
âThe greatest challenge I have is during the summer,â said Aguila. âOn average, I paid $800 per month for irrigation water. Even if I do not use a drop, I still get charged a minimum of $200 per month. So, I need to conserve and use as little as needed.â
Looking for help, Aguila discovered the USDA Natural Resources and Conservation Service (NRCS), where he met Soil Conservationists Daniel Holtz and Axel Sanchez. Together, they came up with a conservation plan, and eventually applied for financial assistance through the Environmental Quality Incentives Program (EQIP), to address gully erosion with an underground outlet pipeline, installed a new, efficient irrigation system, and began an irrigation water management (IWM) regimen.
Additionally, Aguila has diversified his crops with dragon fruit and cherimoyas, and propagates the plants himself, producing three varieties of dragon fruit: American Beauty (red flesh), Delight (white flesh), and Physical Graffiti (light purple flesh). In the future, he plans to begin selling these potted plants to help him cover operating costs, while the orchard matures and recovers from a prolonged drought.
Aguila remains committed to learning more and more about farming. Recently, he planted 100 more avocado trees and enjoyed his daily work of watering the potted dragon fruit, removing hungry snails, building more trellis, and various other projects. Additionally, he has been attempting to establish local Asian markets for commercial customers.
âThe best advice I can give to other farmers is to âget your hands dirty,ââ added Aguila. âDon't depend on one crop. Try to diversify as much as possible. And, conserve resources as much as possible as well.â

As designed, spring snowmelt carried by the Columbia River backfills into the historic floodplain at Steigerwald Lake National Wildlife Refuge in southwest Washington, June 20, 2022. USFWS video: Toshio Suzuki
After years of restoration work, Steigerwald Lake National Wildlife Refuge reopened in May of 2022 and is doing exactly what it was designed to do: Allow spring snowmelt from the Columbia River to fill the historic flood plain.
The massive, 960-acre project included levee deconstruction, fish relocations, the raising of a highway, and the planting of more than 500,000 trees and shrubs at the refuge east of Vancouver, Washington.
The two-year project, referred to as the largest habitat restoration project ever on the lower Columbia River, is already creating new space for wildlife.
