[Abstract]:How to better mine the "three down" coal compaction has become an important research content in the field of coal mining, and the filling mining technology is to fully and effectively exploit the "three lower" coal compaction. This paper, based on the basic properties of ultra-high water materials and the application of ultra-high water material filling mining in CG1301 face of Yineng Coal Mine, analyzes the relevant theory of filling mining according to the green mining technology of improving the mining rate of coal resources and controlling the surface subsidence. By means of numerical simulation analysis and field measurement analysis, the movement law and control mechanism of surrounding rock in super-high water filling mining in medium and thick coal seam are preliminarily analyzed. The main conclusions of this study are as follows: (1) the present situation of filling and mining of medium and thick coal seams at home and abroad is summarized, and the research content and technical route are determined. (2) by analyzing the characteristics of filling and mining of ultra-high water materials in medium and thick coal seams, The filling method suitable for filling mining in medium and thick coal seam and its advantages, disadvantages and applicable conditions are summarized. The relevant theories of overburden control in goaf filling mining are summarized as follows: filling mechanics, key layer theory, equivalent mining height theory and void volume conservation theory. The control mechanism of overburden deformation controlled by ultra-high water material filling body is expounded from three aspects. (4) the control mechanism of overburden mining with ultra-high water material bag filling in medium and thick coal seam is analyzed in detail, and the surrounding rock movement law is obtained by numerical simulation. It is concluded that the physical capacity of ultra-high water material filling can effectively control the surrounding rock movement, and with the increase of goaf filling rate, the better the control effect of surrounding rock is, through the analysis of the application of super-high water material filling mining engineering in medium and thick coal seam. It is concluded that the technology can not only control the wall rock movement in goaf, but also have remarkable economic and long-term social benefits.
