The stress state and mechanical response of the filling body along the remained roadway were studied. Specifically, firstly, the supporting pressure of the coal pillar which is on one side of the gob-side remained roadway was deduced.Also, an equation that is used to calculate the width of the balance area in the stress limit state was acquired. Then, an equation that is used to calculate the roof cutting force on one side of the supporting body was obtained. By using FLAC3D, the authors investigated the displacement field and stress field response laws of rock masses around the roadway with different filling body's widths. The results show that with the filling body's width increasing, the supporting ability of the filling body increases.Meanwhile, the rock mass displacement around the roadway and the filling body deformation decrease.The better the filling body's supporting effect is, the higher the roof cutting force will be. When the filling body's width is larger than 3.0 m, its internal bearing ability becomes stable and the filling body's deformation became non-apparent. Finally, analysis shows that the filling body's width should be 2.5 m.Furthermore, the authors conducted field tests in the supply roadway 1204, using high-water materials and acquired expected outcomes.展开更多

I argue the antithesis: Cage's 433" satisfies Langerian aesthetic theory, and is indeed "aesthetic" music. Cage does something more: he satisfies Langerian aesthetic theory, yet he is not limited by it. He does not simply create music, nor does he offer listeners a musical space. He creates what Gilles Deleuze and Fe1ix Guattari (1987) call a line of becoming that passes between music making and a musical space. In 4 minutes and 33 seconds of silence, Cage presents a sense of emptiness and numbness felt simultaneously with fullness and explosion. In what appears to be stillness, the listener experiences the flux of movement; what appears to be devoid of depth, is filled with complexities. 433" embraces chance, uncertainty, and the unknown; it is an experimental process; it is becoming-music in 4 minutes and 33 seconds.展开更多

Its main idea is providing detailed information about economic events that allow individual users to generate their own input values for their own individual decision model. From existing literature, we can find that this theory has not formed a perfect system, study on it is not deep and the theory itself has some drawbacks. The goal of this paper is to introduce this theory systematically. By analyzing the drawbacks of this theory, this paper proposes some solutions to improve it.展开更多

For the restricted emergency rescue resource in a single city, it has become more and more imminent for the demand of the intercity collaborative resistance to major accident, so as to improve the protection capacity of urban security. In order to find an effective intercity, emergency rescue collaborative system, this paper introduces the concept and analysis method of ecosystem theory into intercity emergency, rescue. Based on the analysis of the formation-process of emergency rescue individual, population and community: a throe-level intercity emergency rescue collaborative system is constructed according to the characteristics of dynamics and structure of intercity emergency rescue ecosystem then the collaboration mechanism of information, resource and process in the interceity emergency rescue ecosystem is also studied in this paper; so as to offer available strategy and method for the ecosystem theory applied to intercity, emergency rescue. Through the studies of intereity emergency rescue ecosystem. it illuminates that the proposed emergency system can not Only cope with the major accident more timely and effectively but also integrate the intercity information resources and emergency rescue resource and process optimization.展开更多
