After the experiments of the foaming ability and the wetting ability to different dust grains with different particle diameters, the results show that the new foaming agent can reduce the surface tension of solid and liquid materials rapidly with good foaming and wetting abilities.
Experimental Materials By comprehensively considering the foaming, solubility, cost, environmental protection and other factors of surfactant, select 12 surfactants from a large number of surfactants, with the active substance content of 92% to 95%.

Space graphical information can accurately describe the spatial location of each mine, this series of work in GIS technology through the coordinates (X, Y) can be well represented; while mine attribute information very large amount of data, it collected a lot of land mines material characteristics, as well as all kinds of mining equipment, not only for the implementation of information technology equipment control, but also on the roadway and other fixed facilities monitor the entire process, reflected in the geometric data model, these are represented by the geometry of production work they are the point, line, surface collection of objects, and through these surface features can be combined into all feature mining environment, and each have their own characteristics and properties of geometric features [2].
With the advancement of science and technology, the study of modern Flex RIA technology has gradually deepened, I believe in the future of science and technology is more advanced, GIS information management model will make more outstanding achievements in the field of coal range, resulting in a more profound impact.

However it doesn’t consider the internal stress and strain relations in rock and soil mass; it needs to assume the critical sliding surface; and it isn’t suitable for the calculation of the non-homogeneous material and complicated slope, etc.
