Combining EH4 geophysical prospecting, TSP203 geophysical prospecting in the cave and early exploration results, we can know that the material composition and boundary of fault zone (the max thickness of fault weakened zone is 26m, and completely weathered granite gives priority to the filling.), from which we can judge to be weathering granite fault.
As calculation parameters are uncertain, a variety of material parameters are taken in calculation, as follows.
Elastic modulus of support material is 22000(MPa), Poisson ratio is =0.2, weight is 25(kN/m3), cohesion is 3000(kPa) and internal frictional angle is 60°.

Along with the rapid development of chemical industry and the progress of science and technology, there exist safety risks for a large number of risk source pipelines.
Introduction Along with the rapid development of chemical industry, many industrial factories, tank farm and warehouse store with a lot of dangerous chemicals, most of the hazardous chemical materials of an inflammable, explosive, toxic and harmful and corrosive.
It can also be used for the rescue sealing for gas, heat, and water pipes; l It is reusable, thereby saving material and energy, making a great environmental improvement.

Study on Single-Pulse Discharges under special Flushing Conditions Markus Munz1, a, David Sternkopf 1, b, Rüdiger Haas 1, c 1Hochschule Karlsruhe – Technik und Wirtschaft, University of Applied Sciences, Institute of Materials and Processes (IMP), Moltkestraße 30, 76133 Karlsruhe, Germany amarkus.munz@hs-karlsruhe.de, bdavid.sternkopf@hs-karlsruhe.de, cruediger.haas@hs-karlsruhe.de Keywords: Single-pulse discharges, volume flow, EDM drilling.
Single discharge experiments are done to explain the effects of the discharge current, the discharge duration, dielectric fluids or properties of used materials.
The more resolidified material is located at the crater edge, the less material is removed from the discharge spot.
Figure 7: Removed material at different flushing conditions After the drop of removed material on the tool electrode at 10 l/h the removed material increases with an increasing volume flow.

Safety of facility materials.
The materials which are used in the external area of hospitals consist of stone, plastic, metal, wood, and concrete.
The materials should be hard wearing, deslick, and anti-rotting, especially the facilities that close to people.
Last, the materials are general.
Therefore, the materials selection should be considered, such as metal garbage can.

Experimental Materials.
All the materials used for the test are offered by a ready-mixed concrete plant.
The Concrete mixing materials presented in Table 1 are shaken through the sieve of 10mm, and the screenings are cast to 40×40×160mm standard specimen respectively.
