Discrete element method is used to analyze the working principle of bolt used in gateway excavated in inclined seam,which indicates that it is necessary to adopt comprehensive support system.
Combined with the projects general situation,it introduces the application of combined support technology of slope-cement mixing pile foundation in this project and its construction methods and construction requirement,and represents the detection requirement of foundation,to give the reference to the similar projects.
Under the influence of high stress and mining pressure,deformation law of surrounding rock of in seam roadway in deep mine is researched,and a combined support technique of using belt and bolting wire mesh,adapting to the deformation of surrounding rock of in seam roadway in deep mine,is put forward.
In this paper, an example of successful construction for a comprehensive supporting structure is presented , in which cement mixing piles and bored piles were used and the reinforced concrete ring slab bracing was set at the top of a pile. The paper can be used as reference to deep foundation pit supporings of soft soil grounds.
The practice has proved that all of the supporting systems can play their advantage by using comprehensive supporting system in the design of deep foundation pit in the soft soil layers. And it can make up for the shortcomings of every supporting system, thus the cost can be retrenched and the time can be shortened.
Current results provide the most comprehensive support for the notion of multi-M-mode synergies stabilizing time profiles of important performance variables in motor tasks involving large muscle groups.
In this article, we propose a comprehensive support ofmultidimensional discrete data (MDD) in databases, including operations on arrays of arbitrary size over arbitrary data types.
However, comprehensive support for the integration of interdependent, possibly conflicting concerns related to synchronization behavior is still missing.
