The maximum main stress of a rotating abrasive ring runs in the tangential direction.

FIG. 3 describes the safety concept of “Loss of the main voltage.”

The results were consistent in showing a NNW-SSE to N-S orientation of the maximum horizontal principal stress SH.

Accordingly, the magnitude of the maximum principal stresses is limited so as not to exceed the maximum principal stress .

These recesses have two central bulges through which the main stress is further relocated towards the axis of rotation of the electrode.

For the purposes of treatment, the injectible preparation is injected directly into that area of the affected tendon at which the main tension occurred.

The present invention has the advantage that the pressurization of the coal seam from which gas is to be extracted with a pressure that is less than the lowest principal stress determined in the seam in question opens the complex fissure system present in the coal in the pore range of macro pores up to micro pore structures, without new fissures in the range of the macro structure opening or having to open.

Subsequent to the opening-up of the pore structure, the micro fissures do not return to their tight or impermeable starting position since due to the longer lasting pressurization with a pressure that is in the range of the principal stress, a low dislocation of the micro fissure surfaces relative to one another is produced, and due to the separation of very fine particles connected therewith, a permanent gap is generated on the respective fissure surface, so that advantageously it is also possible to eliminate the use of support material such as sand, etc.

The basic concept of the present invention is that to open up the coal, pressurization of the bore hole that is effective over a prolonged period of time is established with a pressure that is less than the lowest principal stress determined in the respective seam layer from which gas is to be extracted, whereby the pressurization of the bore hole is effected during the opening-up time period with a cyclically fluctuating pressure.

This long-lasting pressurization with the pressure that is a function of the given principal stress leads to the desired opening-up of the pore structure of the coal without alterations in the mechanical structure of the coal seam developing.

For the present application Tosca Structure.shape modifies the surface of the front notch for minimizing the highest first principal stresses.

As with the vertical section, in the active stress state the larger stresses in the hopper are also acting downwards (major principal stress acts vertically along the hopper axis).

The module has a special output to warn of main supply failure - a classic UPS function.

In the hopper (at least beneath a sufficiently large distance from the vertical section)Â the major principal stress s 1 is proportional to the local hopper diameter (figure 5).

The direction of the maximum horizontal principal stress, SH, was found to have a tectonically plausible azimuth of 131° ± 10°, which is almost per pendicular to the front of the Axen nappe.

To compare various strained states, the simple tension (compression) is accepted as the universal measure, with the principal stress .

The orientation in which the strain gauge is mounted, i.e. the angle relative to the first principal stress direction, is derived from the material-dependent Poisson's ratio.

Normally the low stress directions lie in the horizontal since the perpendicular lithostatic pressure (from the gravity of the supporting rock layers) forms the main stress without further influences.

Therefore, the stresses acting in the horizontal direction become the larger stresses (major principal stress acts horizontally in the hopper axis).

In the approach according to Rankine, it is assumed that failure is caused by the maximum principal stress (see Chapter 8.24).

The coexistence of mechanisms that usually are mutually exclusive is evidence either for a spatially heterogeneous stress regime or for small differences between the magnitudes of maximum and minimum compressive stress.

In the hopper (at least beneath a sufficiently large distance from the vertical section)the major principal stress s1 is proportional to the local hopper diameter (figure 5). It decreases to zero towards the imaginary hopper apex.

The borehole is 3,901 m deep, is at an angle of 30° in the lower section and was diverted in the direction of minimum horizontal principal stress.

The results of the hydrofrac stress measurements gave amounts for the minimum and maximum horizontal principal stress (Sh and SH); these show clear variations and increase with depth in a non-linear manner.

The reason for the switch can be clarified with a consideration of plausibility: A relatively large vertical stress sv acts on the bulk solid in the hopper because in the vertical part of the silo the major principal stress acts downwards.

Consequently, the 1st principal stress is directly related to the fatigue and lifetime of the shaft. During the automated optimization the notch is changed from its original radius to a conceptual different curvature.

Even when communications systems are used to conserve wiring, the protective device must still be connected via wiring, as this wiring ensures that an auxiliary switch on the protective device transmits the report relating to the state of the protective device. However, an auxiliary switch on a circuit breaker does not recognize the lack of power supplied by the mains voltage.
