Status, Problems and Countermeasures of Mine Shaft Wall Rupture Mechanism
The rupture and deformation of Shaft wall in the vertical topsoil in coal mining, which appears on the common and also is relatively unique phenomenon in China. Today with the increasing of the deep and extra deep Shaft, the destruction of the Shaft wall brings us more difficult task. To solve this basic problem need to figure out the shaft wall rupture mechanism. This paper discusses the current research status of the shaft wall, existence problems and content of the research. We did a lot of engineering investigation and analysis. Focus on the structure design of the wall, the main factors of influence rupture, mechanical characteristics of side wall and etc. Summarizing the shortage that in the study of the shaft wall rupture mechanism, making a supplementary. At the same time, the corresponding relationship between the vertical pressure with the groundwater level, between the groundwater level with vertical additional force. Maximum value of the vertical additional force. The inner link between vertical additional force with vertical pressure, with the depth of surface soil, with the diameter of the mineshaft, the thickness of side wall, the measures for preventing vertical shaft flood. From the five aspects, which reveal the content, analysis the object of study, and show the important significance of research.
