He proposed a proportionality coefficient of 0.33 whatever the materials.
The effect of the contact geometry and the nature of the contacting materials are dominating factors
These two challenges are close to a precise knowledge of structural materials.
A third body always separates the contacting materials and usually imposes a dominating action.

The diagram of support strength and the peripheral pressure of loose circle On the base of the above analysis, for a thicker roadway in soft rock strata, the initial support of surrounding rock must have high strength, which can guarantee the hulking force of rock mass in loose circle quickly achieve the required numerical and quickly inhibit the development of the loose circle.on the other hand, It can also reduce the length of the bolt, save the cost of materials, achieve the goal of safe and economic.
