In order to reduce the touchdown vibration and flying stone splash when the chimney is collapsed, 6 buffer dams shall be built at the vertical collapsed center line within ±6° range of collapsed chimney center line, within 90~170m range away from chimney’s root center, the dam materials are the coal ash, buffer loess, yellow sand etc., upper width is 2m, lower width is 6m, length is 39m~75m, height is 3m, dam spacing is 17m~20m, 2m deep vibration reduction - dust fall auxiliary slot shall be excavated between every two buffer dams, this auxiliary slot increased the buffer dam height and width in disguised form in the practical work.
In order to reduce the ground broken stone splash resulted from chimney touchdown, the buffer dam material should be without brokens, use 2-layer high strength sunshade net to cover the buffer dam so as to form a whole, and the woven bags with yellow sand closed shall be stacked in order at the dam top and the chimney collapsing side, lay 3 layers.
Strictly inspect and accept the quality of blast holes; Ensure the good tamping quality, and strictly prohibit the broken stone mixed in stemming when clogging the blast hole; Determine the appropriate charge quantity based on field test results, to avoid over–charge; Cover the charge parts, use the multi-layer flexible composite materials for cross nearby protection, hanging-cover the charge part by the 20 layers of dense mesh safety net and 3 layers of geotextile to prevent the overflow of flyrocks.
The multi-layer flexible composite materials for cross nearby protection can effectively control the flyrocks.

The starting material for MOS transistor manufacture is thin germanium on insulator.
Bevelling is routinely used in preparation of samples for SRP and can be useful in Raman spectroscopy analysis, where there is a requirement to probe deep into materials.

However, until now the microstructure of raw materials (including ores) is usually still only described qualitatively, whereas the search for systematic relations between relevant processing parameters, product characteristics and inherent textural attributes requires quantification of the microstructure description of raw materials.
Originally this method was used mainly for medical purposes, but in recent years it has being used first in petroleum geology [4, 5], and then in technological mineralogy, enrichment and materials technology [3, 6, 7].

Although independent management has been realized, it cost massive manpower and material resources.
The raw materials of concrete are so many; including cement, fly ash, water, carpolite, grit, additive, etc., the ratio of these materials will affect the compressive strength, flexural strength of concrete.

In order to evaluate different gettering strategies for SOI wafers by using computer modeling, one has to know with sufficient accuracy the diffusivity and segregation coefficient of transition metals in SiO2, as well as material parameters required to describe the gettering techniques typically used in combination with SOI, such as polybackside gettering and internal gettering.
