Mining Face

As mining process in the Mechanized mining face, making it easy come with flap top[1] along the the upward and downward entries. In this paper, through the use of carbon dioxide cannon, we do pre-split blasting experiment on triangular flap top in mechanized mining face, exploring an effective solution to a large area of goaf flap top suddenly breaking down, with the hurricane caused damage and fan-out of toxic and harmful gases, to achieve the purpose of production safety.

AbstractThe synthesis of highly complex two-dimensional (2D) metal nanoframes remains a great challenge. Synthetic strategies for preparing 2D metal nanoframes are few, and rational and systematic synthetic pathways to more complicated architectures have not yet been reported. Herein, we demonstrate a stepwise synthetic strategy for complex 2D metal nanoframes with a high degree of intricacy; the strategy leads to a variety of shapes, including rings, triangles, hexagons, and tripods with tailorable single or double frames in a single entity. These nanoframes of high homogeneity could be obtained through selective combination of four different chemical toolkits consisting of selective etching and deposition on certain facets, and concentric and/or eccentric regrowth by controlling the mismatches of lattice constants of metals. The resulting nanoframes were highly homogeneous in size and shape and had van der Waals interactions that maximized rim-to-rim contact, allowing them to uniquely self-assemble into large-area superstructures.

Mechanical Rigidity

In a footnote to my paper entitled “ The Law of Distribution where one of the Phases possesses Mechanical Rigidity," I attempted to show how the results obtained by Professor Trouton for the absorption of water vapour by cotton could be reconciled with those obtained by me in the case of similar systems, such as carbon dioxide and amorphous carbon. As the apparatus I had employed in the investigation referred to was particularly suited to the accurate measurement of low pressures, I obtained Professor Trouton’s permission to repeat his work, and to investigate the relationship of pressure and concentration for the systems water-cotton and water-wool at the temperature of melting ice. I was particularly anxious to redetermine the lower portions of the curves, for as in Professor Trouton’s experiments the material was dried at the air temperature, it appeared probable that it contained water at the commencement of the experiment, and that the true origin of his curves lay further to the left than the results appeared to show. If this were the case, the true curve representing equilibrium in the system water-cotton might closely resemble those representing equilibrium in the system carbon dioxide and amorphous carbon.
