The Well East Coal Side Site For West Upper Creep Slope Drainage And Anti Sliding Pile Reinforce Design Research

Open-pit mines of china are numerous, increasing the scale of open-pit mine slopestability relates directly to mining areas of economic development and people’s personalsafety of mining area. In this paper the research object of shanxi coal industry plazasurrounding Wells east steep slope there exist a great number of geological hazardpoints, including the slope, sliding slope creep damage, ground fissures, not only suchdisasters seriously affects the normal production of mining workers activities andproduction order, but also its hidden body once the occurrence collapse, landslides, suchdisasters will be caused large number of casualties and serious financial losses.Therefore, the coal industry plaza surrounding Wells east steep slope hazardmanagement has the important practical significance.In summary this topic at home and abroad on the basis of the relevant researchresults, this paper takes the coal vice drill Wells for upper vermicular slippery slopewest for analysis, an investigation and theoretical analysis, the main research contentsare as follows:⑴Combined creep slope geological data, topographic features and thesurrounding environment, the application of MIDAS/GTS numerical simulationsoftware on the creep strain and displacement of slope is simulated and analyzed andthe slope stability is evaluated；⑵According to the simulation results of slope in the presence of red clay and itseffect on the properties of creep slope was analyzed, the layer of red clay slope creepsliding thing important potential factors；⑶Creep slope for the specific situation to determine the principles of drainageworks proposed to the main groundwater drainage holes, cut surface, drainage,supplemented by a combination of surface and underground drainage slope drainageway；⑷Study of the open pit slope is reasonable, effective reinforcement method,analysis of anti-slide pile reinforcement principle and advantages, determined theanti-slide pile reinforcement creep slope design. Research of anti slide pile designprinciples,content and way of strengthening, studied the anti slide pile working phasestress characteristics and calculation method of internal force and the application ofMIDAS/GTS software to add after the strain and displacement of slope is simulated andanalyzed, the effect of reinforcement and slope stability is assessed reasonably. In this paper, the creep slope drainage patterns and anti-slide pile technology,significantly improve the stability of the slope, to ensure the safe production and minesafety, can provide reference projects of similar slope.
