Make underground roof support systems without collapse.

Provide analyses to develop ground support systems for the most challenging conditions. It is therefore very crucial for homeowners to identify and act on signs that a roof is in danger of collapse. The collapse of the overburden strata above an underground opening can be subdivided into two groups. While this is a good idea it has its drawbacks.

Extreme weather conditions are the most common cause of roof collapses. It is imperative to inspect your roof deck regularly and respond accordingly to any structural damage that might cause roof failure. For both cases mine designers need to be able to predict if and how the failure will occur. Roof sag or roof collapse forces.

Rock on the other hand behaves a little bit differently in that it does have some tensile strength. This is why many tunnels are lined with materials like steel or concrete to provide support to the tunnel walls and transfer the stresses in the subsurface around the tunnel. 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. This is overcome by using concrete.

Construction plastic sheeting is laid out in the hole of depth where the roof shall rest. The cheapest roof making method is leaving it round a square house don t care what shape roof it sits under. We include photographs of collapsing wood framed roofs and photo sequences. So i have 15x15 interior rooms on either side of a 3x15 walkway that i use for my killbox in my mountain base.

The 15x15 rooms where i plan to plce my turrets keep caving in in the middle. While some earth sheltered homes are built completely beneath ground level many are constructed using a technique known as berming. Undesirable eg collapse of the roof above a roadway although some are expected eg the collapse of the overburden above a longwall panel. 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.

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.
