It was also stated in the deal that the backfill
average height shall be up to 2.5 meters.
The paste backfill
plant has been commissioned and paste backfilling has begun in the upper levels of the Turmalina mine.
The influence of the filling mining method on the stability of the mine and the induced surface settlement deformation are closely related to the strength of the cemented backfill
. Therefore, the determination of cemented backfill
strength is a crucial part of the filling mining method.

mining method is commonly employed in the mineral resources exploitation for nonferrous and precious metals.
Clause 53 (Staffing Arrangements) of the Public Health System Nurses' and Midwives' (State) Award 2017 talks about the requirements to backfill
These inspections included a drone flyover, during which the DEP took photographs and turned them into a topographic map to estimate how much backfill
the workers had placed, said department spokeswoman Virginia Cain.
Advantages of micro trenching include increased installation production and reduced backfill
costs associated with the minimal cutting width; avoidance of existing utilities, due to the shallow-depth placement; and a cleaner job site, thanks to the vacuum spoil that removes debris.
To date, studies of the static stability of retaining walls have investigated influences such as wall height, wall width, uniform loads, and the cohesion and internal friction angle of the backfill
on the static stability of retaining walls.
Kerosene-type jet fuels are sometimes required to be stored in bulk in tanks with earthen backfill
. No single code or standard addresses the requirements for construction of such tanks, which needs a multidisciplinary approach.
