The cement industry, as a primary trade, plays an important role in the development of a country's organization. This industry in Iran, however, despite of profuse benefits such as high-value mines, faces many challenges. Problems such as exploitation of the production require the need for doing research into this area. The main purpose of this paper is to examine the Eco-efficiency in Iran's 2...

China’s shallow coal resources are gradually diminishing, and deep have slowly become the main energy source. However, destruction mechanism evolution of rock formation structure not clear, which seriously restricts exploitation utilization energy. Here, optimization physical parameters deformation law overlying in a mine Shandong Province were studied with an integrated approach including simi...

With the increase of mined-out areas and geological disasters, it is necessary to study influence range mining. Moreover, with growth in amount data, machine learning methods are commonly used predict surface subsidence. The 10 mm subsidence boundary an important indicator determine range, FLAC3D suitable for solving nonlinear large deformation problems. Therefore, can be explore relationship b...

Owing to the growing amount of digital information stored in natural language, systems that automatically process text are of crucial importance and extremely useful. There is currently a considerable amount of research work (Sebastiani, 2002; Crammer et al., 2003) using a large variety of machine learning algorithms and other Knowledge Discovery in Databases (KDD) methods that are applied to T...

Anchor cables often break in various forms. Tensile failure can be resisted by using high-strength materials, while there is no good solution for shear failure. A new supporting structure called Cable and C-shaped tube that bear the transverse force was invented a preliminary introduction to mechanism of given. Field investigations in-situ stress tests were carried out on panel 3210 Nanguan Min...
