Make Underground Roof Support Systems Without Collapse

Roof sag or roof collapse forces.

Make underground roof support systems without collapse.

Provide analyses to develop ground support systems for the most challenging conditions. We include photographs of collapsing wood framed roofs and photo sequences. For both cases mine designers need to be able to predict if and how the failure will occur. While some earth sheltered homes are built completely beneath ground level many are constructed using a technique known as berming.

The cheapest roof making method is leaving it round a square house don t care what shape roof it sits under. I was under the impression that you could make 16x16 rooms under a mountain without it collapsing and i have two 17x17 rooms with one support elsewhere in the base that have never collapsed on me. In your blog about using a membrane as an underground roof you suggested laying a sheet of rigid foam below the surface to keep the ground warm. This is overcome by using concrete.

Extreme weather conditions are the most common cause of roof collapses. The 15x15 rooms where i plan to plce my turrets keep caving in in the middle. Kms uses the roof instability rating rir system along with the latest in proprietary finite element modeling to provide precise and accurate analysis prediction and site specific ground control design. So i have 15x15 interior rooms on either side of a 3x15 walkway that i use for my killbox in my mountain base.

It is therefore very crucial for homeowners to identify and act on signs that a roof is in danger of collapse. These lining systems add a major cost to the tunnel construction. Reinforcing rods mesh is then laid on top which is covered by concrete. While this is a good idea it has its drawbacks.

Rock on the other hand behaves a little bit differently in that it does have some tensile strength. Construction plastic sheeting is laid out in the hole of depth where the roof shall rest. It is imperative to inspect your roof deck regularly and respond accordingly to any structural damage that might cause roof failure. Earth bermed homes are built largely above ground but piles of soil are then pushed up against the walls all the way to the top to form a protective cocoon of earth and vegetation that will separate the outer shell of the home from the open air.

Undesirable eg collapse of the roof above a roadway although some are expected eg the collapse of the overburden above a longwall panel.
