As a result, mankind must turn our attention to new energy structure, explore and research to develop renewable energy vigorously, replace all biochemical resources as renewable energy resources and raw materials.
Similarly, replacing the old building structure also consume energy, such as demolition, piling, recycling, manufacturing new building materials.

Introduction The mass movements, considered to be the most important geomorphological process to shape the terrain, are the downslope movement observed by varied materials under the influence of gravity.
According to [2], these materials are characterized by their highly unstable heterogeneous character and geotechnical behavior, which acts on the weight increase over the slope, thus, helping to spark movement occurrence.
In accordance with [5], the key for risk classification is the presence of instability features that indicate occurrence or imminence of mass movements in slope.

Introduction Medicaments applied in coal preparation technology are mainly collecting agent and foam beater, and regulators is seldom used, but during the process of high-ash-difficult-to-separate coal slime flotation, carried fine slime is key factor affecting concentrate coal quality.
Fine coal slime materials are not easily covered on coal particle surfaces.
Soluble glass itself has viscosity, having some foaming function mixed with materials, increasing the difficulty to furtherly reduce fine coal ash content.
